Introduction

Welcome to RayTech Navigator

This User’s Guide describes how to use Raymarine^®’s RayTech

Navigator marine navigation software (Figure 1-1). RayTech

Navigator operates within a standard Windows^®environment, and

enables you to utilize the latest digital charts and Global Positioning

System (GPS) instrumentation to help you pilot your vessel to virtually

anywhere in the world. Navigator easily interfaces with your boat’s

onboard navigational systems, offering you the flexibility to allow

Navigator to autopilot your vessel to any destination you choose to

plot. Navigator also incorporates the capability to download the latest

weather and oceanographic information and display it on any chart,

thus keeping you apprised of foul weather near you or your destination.

Furthermore, Navigator is the perfect choice for the serious sailor

or fisherman, offering advanced optional modules that enhance

Navigator’s route-plotting and fish-finding performance. The subsec-

tions that follow detail the sophisticated capabilities and features of

RayTech Navigator.

RayTech Navigator User’s Guide

Easy Marine Navigation Using Routes and Waypoints

RayTech Navigator takes the guesswork out of marine navigation by

enabling you to easily chart, plot, and execute simple or complex

routes. A route is composed of a series of waypoints that you select

on the screen, with each waypoint denoting a certain position along

the path of the route. A route typically has a starting waypoint and an

ending waypoint, and as many intermediate waypoints as you need or

want. Using Navigator, you can create a route to any destination with

a few simple clicks of the mouse, and then follow it manually or

enable your vessel’s autopilot to follow the route/waypoints you have

designated. Routes and waypoints can easily be changed “on the fly,”

should weather or other factors necessitate a change in course.

Multiple Chart Formats for Flexibility

Navigator uses the latest digitized versions of the paper charts

traditionally used in marine navigation, and supports a variety of

popular chart formats:

· C-Map^®NT

· Maptech^®NOAA/BSB

· Maptech PCX

· Maptech Photo Regions and Topographical Charts

· SoftCharts^®Nautical Charts and PhotoNavigator

These charts fall into three basic types:

· Vector –

A paper chart that has been digitized

into a format consisting of line segments.

Vector charts can be easier to read than

a rasterized chart, but may not include

the level of detail found in Raster charts.

The C-MAP chart is an example of a

vector chart.

Introduction

· Raster –

A paper chart that has been scanned into

a high resolution image. A raster chart

has the advantage of being virtually

identical to the original paper chart from

which it was scanned. The MapTech

NOAA/BSB and PCX charts are

examples of raster charts.

· Aerial Imagery – A high resolution, geo-referenced rasterized

photograph taken from aerial or satellite

sources. You can overlay your vessel’s

position on such an image, and get a

visual estimation of your position with

reference to actual, photography-based

landmarks. The MapTech Photo Region

chart is an example of an aerial imagery

chart.

Comprehensive Weather/Oceanographic Reporting

Navigator offers you the capability to download and display the latest

weather and ocean conditions, and then superimpose this information

upon your charts in several layers. Weather and oceanographic (sea

tides and currents) files (in GRIB format) can be downloaded directly

from the internet or requested via email. After you have acquired your

files, you can fully animate them to show the predicted weather and

ocean currents over a specified period of time. Typical weather files

contain information in 6, 12, and 24 hour intervals, covering a period

of several days. Navigator can further break this information down

into intervals as small as 30 minutes, giving you a comprehensive

presentation of atmospheric and marine conditions.

RayTech Navigator User’s Guide

Advanced Graphical User Interface with

Customizable Toolbars/Displays

You operate Navigator via an easy-to-use Graphical User Interface

(GUI) complete with many customizable Toolbars, Function bars, and

“floating” Databoxes (Figure 1-2). Using an intuitive menu hierarchy,

you can display only those tools that you commonly use, or customize

screens to show you only pertinent information, with just a few mouse

clicks. You can zoom deeply into charts to display the maximum level

of detail for the region you are in, animate weather and oceanographic

files to monitor the meteorological events in your area, and create

comprehensive logs containing virtually every piece of data that you

might encounter and collect on a voyage. Navigator’s flexible GUI

enables you to tailor its powerful resources to suit your needs quickly

and easily.

Toolbars, Function bars, and Databoxes can

be moved and displayed anywhere you need

Introduction

Integrates with Raymarine’s SeaTalk^®and NMEA 0183

Data Output Devices

Navigator is designed to work transparently with Raymarine’s SeaTalk

data communications package, or any other device that outputs data

in NMEA 0183 format. This enables parameters such as Heading,

Wind Speed/Direction, Sea Temperature, and a variety of others to be

accessed and displayed within Navigator. Navigator can also connect

to such onboard systems as Ockam, B&G, and KVH via a standard

RS-232 data cable. This enables the information collected by

Navigator to be relayed and displayed on your vessel’s standard

onboard instrumentation systems.

Navigator also connects to Radar systems that are capable of

outputting Cursor Range and Bearing, and also to ARPA Radar

systems. This allows targets identified by Radar to be plotted on

directly onto Navigator’s chart displays. You can also connect

Navigator to a variety of proprietary instruments, and generate

comprehensive log files which can then be analyzed from within

Navigator or saved and exported for future external analysis.

3-D Contour Display

Navigator’s advanced 3-D Contour Display shows your vessel, the

ocean floor, and other related information using a 3-D vector-style

display. This enables you to view any area, such as favored fishing

and sailing spots, harbor entrances, and so forth, within a full, 3-

dimensional window. Images can be rotated 360° so you can view

your vessel’s position from virtually an angle. 3-D Contour gives you

useful navigational perspectives that you might not be able to ascertain

from a conventional display.

The 3-D Contour Display includes:

· Past navigational markers

· Depth markers

· Transducer cone images

RayTech Navigator User’s Guide

Optional Modules

RayTech Navigator offer two comprehensive optional modules to

increase Navigator’s capabilities: Sail Racer and Fishing Pro.

Sail Racer Module

Navigator’s Sail Racer Module is targeted toward the professional

sailboat racer, and includes DataTrak, Polars, Route Optimization,

Advanced Weather Routing, Pre Start display, Navigation Numbers,

and a specialized Racing toolbar.

· DataTrak is an instrument-recording program that captures a

variety of incoming navigational and performance-related data

and displays it on time-based graphs in multiple windows.

· Polars uses a group of variables (such as apparent/true/

corrected wind angles, boat speed, heel/pitch, and so forth)

to determine what heading you should set your boat upon to

achieve the best possible speed under varying wind conditions.

Analysis results are displayed using multiple graph plots which

you can modify (edit) to suit your needs.

· Route Optimization determines your ideal route based upon

ocean current, wind speed and direction, in addition to your

vessel’s Polar characteristics, then plots this route upon the

chart you desire.

· Advanced Weather Routing consists of detailed, 7-day

animated weather files, text-based advisories for North

American coastal regions, and offshore forecasts/advisories.

· The Racing toolbar displays special icons that are used within

racing environments such as The America’s Cup, and enables

you to set marks and courses quickly and accurately based upon

GPS or laser-guided input.

Introduction

Fishing Pro Module

The Fishing Pro Module enables you to use Navigator to easily locate

the world’s best fishing areas using up-to-the-minute, satellite-based

oceanographic data.

The module includes:

· The latest ocean temperature data presented as overlays

upon your navigational charts to aid you in finding the

warmer locations where fish may be hiding.

· Plankton content areas of the ocean presented as overlays

upon your navigational charts so that you can easily

identify clear, fish filled waters.

· 3-D bathymetric charts to precisely identify ocean bottom

contours, enabling you to readily pinpoint the areas where

fish are more likely to concentrate.

· Complete engine monitoring capability, which displays

a realistic on-screen gauge cluster (including tachometer,

oil pressure, turbocharger boost, and more). This feature

allows you to easily check your vessel’s engine-related

systems from within Navigator.

Using Navigator’s Interface

Overview

This chapter shows you around Navigator’s user interface, illustrating

and explaining the functions and components of the following:

· Navigator main interface

· Main drop-down menus

· Toolbars

· Functionbars (Standard, Radar, and Sonar)

The sections that follow give you details about all drop-down menu

hierarchies/submenus and how to access them, as well as how to

display the various Toolbars and Functionbars and what they do.

All menu levels and functions are illustrated and described,

enabling you to work smoothly and efficiently within Navigator.

Main Interface Component Descriptions

This section illustrates the main user interface, and identifies its

various components. The interface is composed of standard drop-

down and pop-up menus, Toolbars and Functionbars. You simply

point-and-click to access most functions, and you can right-click on

most any component to display context-sensitive help. Toolbars and

Functionbars can be moved around the Navigator screens and charts

(by clicking and dragging), and “docked” (positioned) wherever you

need them to display. Navigator retains your settings from session to

session, and re-displays the interface the same way each time.

Working With Charts And Routes

Overview

This chapter explains how to use RayTech Navigator to chart and

plot courses for nautical navigation. The chapter is intended to

have you navigating with the basics in the shortest possible time,

and leaves the more complex Navigator operations for Chapter 5,

“Advanced Navigator Functions.” Refer to that chapter if you

already have a working knowledge of Navigator. This chapter

covers the following areas:

· Installing, displaying, and manipulating the various chart types

· Creating, editing, and implementing waypoints and routes

· Getting and using the latest weather and oceanographic reports

Installing Charts

This section explains how to install and load the various chart types

that Navigator uses.

About Using Charts with Navigator

Navigator supports all of the popular chart types, including:

· C-Map NT

· Maptech NOAA/BSB

· Maptech PCX

· Maptech Photo Regions and Topographical Charts

· SoftCharts Nautical Charts and PhotoNavigator

Important: Navigator automatically loads a default World Chart

on each start-up. You cannot close this window or uninstall this

chart — simply open a new window over it.

4-1

Download from Www.Somanuals.com. All Manuals Search And Download.

RayTech Navigator User’s Guide

Working with charts in Navigator consists initially of installing the

charts, after which, you can open and display as many or as few as

you need. The more charts you decide to install, the longer the overall

installation process takes; however, once installed, you can display

those charts at the moment you need them without waiting.

It’s important to keep in mind the difference between

installing the charts into Navigator, and installing the charts

onto your PC from the original manufacturer’s CD. The chart

installation instructions in this chapter describe installation

from a Navigator point-of-view, leaving the explanation of

installing the charts onto your PC to the chart manufacturer.

Refer to the instructions that came with the CD.

Where to Store Charts

The best place to store your charts is on the hard drive of the PC that’s

running Navigator. By loading your most commonly used charts onto

the PC, you always have virtually instant access to them, they load

faster, and they are easier to read under rough conditions (CD drives

can skip tracks if tossed about). The charts, especially photographic

charts, will consume disk space, but with today’s large-Gigabyte hard

drives, it should not be an issue.

Installing MapTech PCX and NOAA/BSB Charts

To install MapTech PCX and NOAA/BSB Charts:

1. Insert the chart CD into the PC.

2. From the File menu, select Settings. The RayTech Settings

dialog box (Figure 4-1) is displayed.

3. Double-click on the Raster Charts icon. Chart Manager

screen 1 is displayed (Figure 4-2).

RayTech Navigator User’s Guide

Working With Routes

This section explains how to plot and edit routes. A route is a path

from location A to location B, and is composed of a series of

waypoints that you “place” on a displayed chart. Each waypoint

represents a certain position along the path of the route. A route

typically has a starting waypoint, an ending waypoint, and as many

intermediate waypoints as you need or want.

The distance between any two waypoints is known as a leg. The leg

of the route your boat is currently traversing is called the active leg.

An active leg consists of an origin waypoint (the waypoint you just

departed) and a destination waypoint (the waypoint you are moving

toward). In Navigator, the active leg of a route is represented by a

dashed line and a blinking gray circle around the destination waypoint.

Plotting a route requires just a few mouse clicks, and you can easily

move/adjust your waypoints after placing them on the screen. Routes

can be as simple or complex as you need, and by offering a wide range

of icons and display colors, Navigator allows you to customize each

route (and individual waypoints) for easy recognition and navigation.

Navigator stores all your favorite or most commonly used routes, and

you can create several backup routes for any destination, should

inclement weather or other circumstances dictate you take a different

course. If you have Navigator connected to a GPS and Autopilot, the

route you chart on the screen can be run automatically.

Note: The subsections that follow presume that you already

have charts installed and displayed within Navigator.

(properties govern how a waypoint appears and behaves on the

screen). Editing routes and waypoints covers the following topics:

· Adding, moving, and deleting waypoints

· Modifying waypoint display characteristics

· What are, and how to place, relative waypoints

· Creating and editing waypoint groups

· Using the waypoint recycle bin

· Adding, moving, renaming, and deleting routes

Setting Relative Waypoints

This subsection explains how to set a waypoint so that it is always

displayed the same relative distance from another waypoint.

To set one waypoint as relative to another:

1. As explained previously, create two waypoints, or, decide

which two existing waypoints you want to use. For the sake

of this example, we’ll call the first waypoint WP1 and the

second WP2.

2. On the chart, double-click WP2. The Waypoint Properties

dialog box is displayed (Figure 4-20).

3. Click the Relative checkbox. The Pinged checkbox appears

to the right of the Relative checkbox.

4. Click the Pinged checkbox to “uncheck” it. The Pinged

checkbox disappears and a drop-down menu with a list of

waypoint names appears. Observe that the Latitude

and Longitude fields also switch to Range and Bearing,

respectively.

5. Click the drop-down menu, and select WP1 from the list.

6. In the Range field, type the range at which you want WP2 to

remain relative from WP1. For example, if you enter 300

miles, WP2 will always remain at a range of 300 miles from

WP1, no matter where WP1 is repositioned on the chart.

7. In the Bearing field, type the bearing at which you want WP2

to remain relative from WP1. For example, if you enter 90

degrees, WP2 will always remain at a bearing of 90 degrees

from WP1, no matter where WP1 is repositioned on the chart.

8. Click OK to save your changes and close the Waypoint

Properties dialog box.

To temporarily set one waypoint to specific coordinates:

1. Double-click on WP2 to display the Waypoint Properties

dialog box (Figure 4-20).

2. Make sure that the Relative and Pinged boxes are checked.

3. Type the specific coordinates for WP2 into the Latitude

and Longitude fields.

4. Click OK to close and save your settings. WP2 is then

displayed at the new coordinates, while WP remains in its

originally position. The previous relative settings for WP2

are stored by Navigator, so you can return the waypoint to its

relative setting when needed..

To return a waypoint to its relative coordinates:

1. Double-click on WP2 to display the Waypoint Properties

dialog box (Figure 4-20).

2. Click the Pinged box to uncheck it.

Advanced Navigator Functions

Overview

This chapter covers the more advanced Navigator functions such as

Radar and Sonar. It also includes information about using Polars

data and graphics to analyze and fine-tune your racing sailboat’s

performance.

Using Radar With Navigator

This sections explains how to use the various Radar functions within

Navigator. Data from your hsb²Series Pathfinder Radar can be

transferred and displayed (repeated) in a Navigator. The radar

output can be displayed in a separate window or overlaid on a chart.

Connection is made from the hsb²connection via a special cable that

inputs to a PCMCIA card in your PC

When a scanner is connected and the radar is in Transmit mode, the

radar picture provides a map-like representation of the area in which

the radar is operating. Typically, your ship’s position is at the center

of the display, and its dead ahead bearing is indicated by a vertical

heading line, known as the Ship’s Heading Marker (SHM).

The radar picture can be viewed with a variety of fixed or customized

range scales. The color of the radar returns (echoes) indicates their

intensity: the strongest returns are shown in yellow and the weaker

are shown in shades of blue. A status bar at the top of the radar image

displays range, current heading and mode indicators for the various

options you can set.

The radar display can show additional information, depending on

your currently selected options, set up selections and the data available

from other equipment. The example displays on the following pages

show some of these features.

RayTech Navigator User’s Guide

The hsb²Series Pathfinder Plus Radar system includes the following:

· Range scales: 1/8nm to 24nm up to 72nm (scanner-dependent).

· Automatic and manual control of tuning, gain and sea clutter.

· Two Variable Range Markers (VRMs) and Electronic Bearing

Lines (EBLs), allowing target range and bearing measurements.

· Target wakes and target expansion mode.

· Add marks to record important or dangerous locations.

· 10 Target MARPA for target tracking and risk analysis.

You can use this chapter with the radar display set to simulator mode,

or on the water after you have installed and set up your hsb²Series

Pathfinder Plus Radar system.

Note: Until you are familiar with interpreting the radar display,

you should take every opportunity to compare the

radars display patterns with visual targets, such as

other vessels, buoys and coastal structures. You should

practice harbor and coastal navigation during daylight

and in clear weather conditions.

You can identify objects using either the radar/chart overlay or the

cursor echo feature: With cursor echo on you can select an object on

the radar display, the cursor is repeated on the chart display so you can

check the objects identity.

Using the Range Control

The radar display can be viewed at various scales by using the range

(zoom) control. The shortest range scale gives a maximum range of

1/8 nautical miles, measured from the default center to the top of the

radar picture. The longest range scale gives a maximum range of

between 24 and 72 nautical miles, depending upon the type of your

scanner.

· The long range scales provide the best overview of your

vessel’s relation•ship to land masses, weather fronts and

large ship targets in or beyond view.

· The short range scales provide greater detail of the radar echoes

close to your vessel, and should be used as you approach the

coastline, harbor or other vessels in the area.

The Pathfinder Plus Radar display includes concentric range rings,

that you can use to help you to judge distances on the radar picture.

Their number and spacing are adjusted automatically if you change

the range scale.

Changing the Range

Each time you click the RANGE button on the Pathfinder Panel,

the range changes to the next available setting.

The range scale and range ring interval indicators, at the left-hand

end of the status bar, are updated whenever you change the range.

Interpreting and Adjusting the Radar Picture

Navigational echoes may be large, small, bright or faint, depending

not only on the size of the object but also on its orientation and

surface. Different objects reflect the radar signals in different ways.

For example, vertical objects such as cliffs reflect signals better than

sloping ones such as sandbanks.

High coastlines and mountainous coastal regions can be observed at

the longest radar range. However, the first sight of land may be a

mountain several miles inland from the coastline. The actual coastline

may not appear on the radar until the vessel is close to the line of sight

distance.

The radar indication may not be similar to your visual observation; a

nearby small object may appear to be the same size as a distant large

object on the radar. However, with experience the approximate size of

different objects can be determined by the relative size and brightness

of the echoes.

Some targets, such as buoys and small boats, can be difficult to

differentiate, since they bob and toss about in the waves and do not

present a consistent reflecting surface. Consequently, these echoes

have a tendency to fade and brighten and, at times, to disappear

momentarily. Buoys and small boats often resemble each other, but

boats can usually be distinguished by their motion.

Not all radar echoes are produced by hard navigational items. Some

echoes may be received from irregularities on the surface of the water,

particularly at close range (sea clutter), or from rain or snow either

around the vessel or in the distance. In addition, some echoes may be

indirect returns to the radar scanner, providing false echoes or multiple

echoes.

The effects of many false echoes can be minimized, and the target

presentation clarified using the controls summarized below. This

section explains how to interpret the radar picture and how the

controls affect the display. It provides instructions for adjusting the

settings, describes the circumstances in which they should be adjusted,

and how they interact with each other.

Identifying False Echo Returns

Not all echoes are direct returns to the radar antenna. Occasionally

signals appear at positions where there is no actual target. These are

called false echoes, and may be caused by side lobes, ghost images,

indirect echoes or multiple echoes.

This subsection briefly describes the echo patterns that can be

produced by false echoes and the likely cause. It should be noted that

the radar operator, through observation, practice, and experience, can

generally detect these conditions very quickly. These effects can

usually be minimized using the radar controls.

Advanced Navigator Functions

Side Lobes

A small part of the RF energy from each transmitted pulse is radiated

outside the single narrow beam. This produces side lobe patterns,

shown in Figure 5-2. Side lobes have no effect on distant or small

surface objects; however, the echo from a large object at short range

may produce an arc on the radar screen similar to a range ring or a

series of echoes forming a broken arc. Side-lobe echoes normally

occur at ranges below 3nm, and can be reduced by adjusting the SEA

control.

Figure 5-2. Radar Side Lobe Echo Affects

Indirect (False) Echoes

There are several types of indirect echoes or ghost images (Figure 5-3).

These sometimes have the appearance of true echoes, but in general

they are intermittent and poorly defined.

RayTech Navigator User’s Guide

Multiple Echoes

Multiple echoes (Figure 5-4) appear if there is a large target with a

wide vertical surface at a comparatively short range. The transmitted

signal will be reflected back and forth between the target and your

own ship. Multiple echoes therefore appear beyond the true targets

echo on the same bearing, as shown in the figure below. This is not

very common.

Figure 5-4. Radar Multiple Echo Affects

Blind Sectors or Shadow Effect

Funnels and masts located near the antenna, may cause shadows.

In shadow areas beyond the obstruction there will be a reduction of

the beam intensity, although not necessarily a complete cut-off.

However, there will be a blind sector if the subtended angle is more

than a few degrees. There may also be multiple echoes that extend

behind the obstruction. This should be avoided by careful selection

of the scanner site prior to installation.

Radar Gain Control

The Gain control adjusts the level of the display of signals received

from the scanner; it is equivalent to a volume control on a radio.

The Gain control can be set either to Auto or Manual modes.

In Auto mode, the Pathfinder Plus radar optimizes the setting.

In harbors or close proximity to land different auto settings may

be necessary to cater for the effects of land clutter.

Alternatively, set both Sea Clutter and Gain to Manual mode, and then

adjust the settings to ensure that all close small targets are visible.

When the Gain control is set to Manual, you should check it every

time you change the range scale. On long range settings, the gain

should be set to give a slight speckle in the background of the radar

picture. On shorter ranges, you may wish to reduce the gain slightly to

reduce the speckle and therefore improve target definition. Do not set

the gain too low, or you may miss small or weak targets. The new

Gain mode (auto or manual) and values are also retained each time

you turn the radar off or on.

Note: Gain can only be adjusted if the control is set to

Manual adjustment. Because the SEA control affects

the gain, you may need to manually readjust it if you

manually change the Gain setting.

To adjust the Gain:

1. Select a range appropriate to the adjustment you want to

make.

2. From the Pathfinder Panel, click the GAIN button.

The Gain Functionbar buttons are displayed.

Click the right mouse button and select View/Control

Panel. The Control Panel appears.

Manual Gain. Important: Because the changes to the

settings are made immediately, you cannot revert to the

previous setting by clicking CLEAR.

5. When you have set the controls to the levels you require,

press ENTER, CLEAR, or BACK to return to the default

level of soft keys.

Sea Clutter Control

Radar returns from waves around your vessel can clutter the center of

the radar picture, making it difficult to detect real targets. Sea clutter

(Figure 5-5) usually appears as multiple echoes on the display at short

range scales, and the echoes are not repetitive or consistent in position.

With high winds and extreme conditions, echoes from sea clutter may

cause dense background clutter in the shape of an almost solid disc.

Figure 5-5. Radar Sea Clutter Display

The Sea Clutter control reduces the gain level in the areas near your

vessel, extending up to 3 to 5nm depending on the wave and sea

conditions. This has the effect of reducing the sea returns to

intermittent small dots, while small targets are still visible. Gain

levels further from your vessel remain unchanged. You can use the

Gain and Sea Clutter control to help minimize the effects of side lobes.

Advanced Navigator Functions

Note: On short range scales, do not set the Sea Clutter

control so high that all clutter is removed, since this

could prevent you from seeing close-echo targets.

The SEA control can be set to Auto-Harbor (default), Auto-Offshore

or Manual mode. In Auto-Offshore mode, the Pathfinder Plus Radar

optimizes its settings to account for the effects of sea clutter. In

harbors or close proximity to land different auto settings may be

necessary to cater for the effects of land clutter. To avoid losing small

targets it is therefore advisable to set the Sea control to Auto-Harbor

mode. Alternatively, set both Sea and Gain to Manual mode then

adjust the settings to ensure that all close small targets are visible.

Note: Because the SEA control affects the gain, you may

need to manually readjust it if you manually change

the Gain setting.

To adjust Sea Clutter control:

1. Select a range appropriate to the adjustment you want.

2. From the Pathfinder Panel, click the GAIN button.

adjustment. Important: Because the changes to the

settings are made immediately, you cannot revert to the

Rain Clutter Control

The radar can see echoes from rain or snow. Returns from storm areas

and rain squalls consist of countless small echoes that continuously

change size, intensity, and position (Figure 5-6). These returns

sometimes appear as large hazy areas, depending on the intensity of

the rainfall or snow in the storm cell.

The RAIN and FTC controls are used to reduce this clutter, so that

targets masked by the clutter can be seen on the radar picture.

· The RAIN control is used to reduce large clutter masses around

your vessel caused by rain or snow.

· The FTC (Fast Time Constant) control is used to reduce rain

clutter at a distance from your vessel, such as that shown below.

Figure 5-6. Radar Rain Clutter Display

When the FTC control is turned up, only the leading edge of large

(rain clutter) echoes is displayed, while the effect on smaller (ship)

echoes is only slight. This means that you can also use the control on

shorter ranges to distinguish between two very close echoes on the

same bearing, which may otherwise merge and appear as one echo.

When the FTC control is turned up, the receiver is less sensitive, and

there is a reduction of background noise and fill-in returns from land

and large targets. You should therefore turn the control down when its

use is not required. Since storm cells are usually visible for long

distances due to their extreme altitude, you may wish to leave them

displayed so that you can observe the location of bad weather.

If you turn the RAIN or FTC control Off (equivalent to setting the

level to 0%), the actual setting is stored, and restored when you turn

Tuning the Receiver

The TUNE control is used to fine-tune the receiver in the scanner for

maximum target returns on the display. In Auto mode, the radar tunes

itself automatically on all range scales. Raymarine recommends

that you leave the TUNE control in Auto mode.

If you set the TUNE control to Manual, you will need to adjust it

about 10 minutes after you have turned on the radar, since the required

setting changes after the magnetron has warmed up.

Adjust the control to obtain the maximum signal strength, as indicated

in the 8-step signal strength bar above the slider.

To tune the radar:

1. Select a range appropriate to the adjustment you want to

make. The optimum Tune setting varies slightly for

different ranges, depending on the pulse width used.

2. On the Pathfinder Panel, click the MULTI button.

3. Press the TUNE button. The button toggles the control

between Auto and Manual mode.

4. Select Manual mode to display the arrow control buttons

and signal-strength meter. Use the up/down arrows to

increase/decrease the Manual TUNE adjustment to obtain

the maximum reading on the meter. Important: Because

the changes to the settings are made immediately, you

cannot revert to the previous setting by clicking CLEAR.

Interference Rejection

Mutual radar interference is likely when two or more radar-equipped

vessels are operating within range of each other. This usually appears

as a series of small dots moving to and from the display center in a

straight line or a long, sweeping curve (Figure 5-7). This type of

interference is most noticeable at long ranges.

Figure 5-7. Radar Interference Rejection Display

The Pathfinder PLUS Radar includes a mechanism that automatically

reduces such interference. This mechanism is normally left switched

on. However, if you wish to detect the presence of other radars in the

vicinity, you can turn off the interference rejection.

Target Expansion

You can make targets easier to see by expanding them. The scanner type

determines the range at which target expansion is available. Target

expansion overrides the normal pulse length, thereby increasing the size

of the target seen on the screen. However, this is at the expense of range

resolution.

RayTech Navigator User’s Guide

Note: When using VRM/EBL, you may want to turn off the

range rings to make the VRMs clearer. To do this,

use the Color control in the Control Panel to change

the color of the range rings to the same color as the

background.

When a VRM/EBL pair is active, its bearing and range are displayed

in its associated data box, which can be moved, deleted or reinstated.

VRMs move if you change the range scale, so that the actual range

you have marked is maintained. VRM/EBLs also move if you offset

the center.

The bearing information is displayed as either the bearing relative to

your vessels heading or (if heading data is available from a position

fixer or compass) the actual bearing in degrees magnetic or degrees

true. These are controlled by the setup parameters.

The VRM/EBL functions allow you to perform the following tasks:

· Measure the range of a target or point from your vessel's

position, using a VRM.

· Measure the bearing of a target or point from your vessel's

position, using an EBL.

Note: Range and bearing measurements are displayed in

the Data box. You can determine the range and

bearing by moving the cur•sor over the target and

checking the Data Box readings. You can also

estimate the range to a target by reference to the

range rings.

When you turn on a VRM/EBL, it is displayed in its last-used

position.

Note: If the VRMs last-used position is outside the radar

picture at the current range setting, it is placed at its

default position instead. This is one third of the range

for VRM1, and two-thirds for VRM2.

Introduction to MARPA

The hsb²Series displays include a Mini Automatic Radar Plotting Aid

(MARPA) function for target tracking and risk analysis. MARPA

improves the standard of collision avoidance by obtaining detailed

information for several automatically tracked targets. MARPA

provides continuous, accurate, and rapid situation evaluation.

You can acquire up to ten targets, which are then automatically

tracked by the MARPA system. MARPA calculates target bearing

and range, true speed and course, CPA (Closest Point of Approach),

and TCPA (Time to Closest Point of Approach).

Each tracked target can be displayed with a vector depicting approxi-

mate target speed (vector length) and course (vector direction). The

target data can be shown on the screen, each target is continually

assessed, and you are warned if one becomes dangerous or is lost.

Effective MARPA operation is dependent on accurate own ships

heading, plus SOG and COG. The better the quality of the heading

data, the better MARPA will perform. (MARPA functions without

SOG and COG data but only relative vector, CPA and TCPA are

shown; target course and speed cannot be calculated).

Safety Notices

MARPA can improve collision avoidance when used wisely. It is the

users’ responsibility to use common sense in navigational judgments.

There are conditions where acquiring a target may become difficult.

These same conditions may be a factor in successfully tracking a

target. Some of the conditions are:

· The target echo is weak.

· The target is very close to land, buoys or other large targets.

· The target or your own ship is making rapid maneuvers.

· Choppy sea state conditions exist and the target is buried in

excessive sea clutter or in deep swells.

· Choppy sea state conditions exist yielding poor stability;

own ship’s heading data is very unstable.

· Inadequate heading data is available.

5-26

Download from Www.Somanuals.com. All Manuals Search And Download.

Advanced Navigator Functions

Symptoms of such conditions are that acquisition is difficult and the

MARPA vectors are unstable; the symbol wanders away from the

target, locks onto another target or changes to a lost target symbol.

If any of these conditions are present, acquisition and tracking may

need to be re-initiated or, in some cases be impossible to maintain.

Improving the quality of the heading data will reduce the effect of

the other conditions.

Risk Assessment

Each target is monitored to see if it will be within a certain distance

from your own vessel within a certain time. If so, the target is

designated as dangerous and you are warned with an audible alarm in

addition to a warning on the screen. The target symbol changes and

flashes to indicate that it is a dangerous target. Pressing any key

silences the alarm and removes the warning, but the target symbol

remains dangerous.

Both the distance (Own Vessel Safe Zone) and the time (Time to Safe

Zone) are selectable.

If a target is lost, either because the MARPA software has lost contact

with it, or because it has moved out of range, you are warned, again

with an audible alarm and an on-screen warning. Pressing any key

silences the alarm, removes the warning and removes the lost target

symbol from the screen.

Target Data

All MARPA targets are stored in a MARPA database list, which

shows bearing, range, course and speed of each tracked target.

For any one target a pop-up data box can be placed on the screen, this

shows bearing, range, course, speed, CPA (Closest Point of Approach)

and TCPA (Time to Closest Point of Approach). The target for which

data is displayed is indicated by a circle around its symbol.

As shown in Figure 5-9, each target is displayed as a symbol to

indicate its status, dangerous and lost symbols are shown flashing:

Target Vector and History

The MARPA targets can be displayed with a vector line showing

where they will be at a certain time in the future, (assuming present

course and speed). You can select a relative or true vector and the

vector length.

You can also select to view the targets history, this appears as a series

of dots that are dropped by the target as it makes way. The interval

between them is selectable.

A relative vector indicates the targets motion related to your own ships

motion. The targets relative course and speed are calculated to produce

a vector that is displayed on the target only. This mode is used for

collision avoidance and threat assessment.

A true vector indicates the targets motion over ground. In this mode

true vectors for the target and your own ship are displayed. MARPA

measures the direction in which the target and own ship are actually

moving over the ground. The result is the vessels true course, the rate

of motion is the vessels true speed. Consider this motion as if you

were in a helicopter looking down watching the targets move across

the water. This mode can aid navigation.

Radar Range Scales

MARPA target acquisition is only available at radar range scales of up

to 12nm, although tracking continues at all ranges. If you change to a

lower range scale, targets may be beyond the range of the scanner and

will be lost.

Using Sonar With Navigator

Data from your hsb²Series Fishfinder can transferred and displayed

(repeated) in a separate Navigator window. The hsb²Series

Fishfinders use sound waves (sonar) to find fish and show the bottom

of a lake or sea. The transducer sends high-frequency sound waves

down into the water; these sound waves strike fish, the bottom, or

other objects in the water and return as echoes. The Fishfinder

interprets these echoes to present an image of the fish and bottom.

The strength of echoes is indicated by different colors. You can use

this information to determine the size of fish and the bottom structure.

Other objects in the water, such as debris and air bubbles, also return

echoes; these echoes are generally weaker than the fish or bottom

echoes and produce background noise or clutter on the display.

Navigator provides controls to reduce the background noise and to

adjust the way in which echoes of different strengths are displayed and

let you select the background color and remove the display colors for

weaker echoes. There is also a White Line feature which helps to

distinguish between the bottom and fish (or other items such as weed)

that are close to the bottom.

Connection is made from the hsb²output via a special cable that inputs

to a PCMCIA card in your PC.

To display sonar data in a separate Navigator window:

1. Make sure the Fishfinder is operational and correctly

connected to the RayTech Navigator PC.

2. Power-on the Fishfinder unit.

3. Click File/Open, then double-click the Sonar icon.

Fish Indications

When the Fishfinder detects a fish, it displays an arch-shaped mark.

In general, a larger arch indicates a larger fish, though this is not

always true. For example, if there are two fish of the same size:

one is close to the surface, the other is near the bottom. The fish that

is close to the surface has a larger arch because, being closer, more

sound waves are returned to the Fishfinder.

The sound waves are actually reflected by an air sac near the center of

the fish, not by the body of the fish. The size of this air sac is different

for different kinds of fish and this can affect the size of fish arches on

the image. A fish with a large air sac produces a large fish arch, while a

fish with a small sac produces a small arch. Several arches together

show a school of fish. Figure 5-11 shows some example target images.

To display the depth of the fish:

1. Click MENU on the Pathfinder Panel

2. Click TARGET DEPTH ID.

Advanced Navigator Functions

Effect of Frequency and Boat Speed

The return from a fish has a different appearance depending on the

frequency used: 50kHz produces a wide beam, so a fish spotted by this

frequency gives a broad arch; the 200 kHz beam is narrower so the

same fish produces a narrower arch.

The shape of the arch is also affected by the speed of the boat. If the

boat is moving slowly, the arches tend to be longer; if the boat is

moving more quickly, the arches are short and peaked. If the boat is

moving very fast, a fish may be indicated by a single vertical line.

In Bottom lock mode the fish arches may appear distorted as the

bottom topography is removed from the image.

Bottom Indications

The bottom usually produces a strong echo, so it is easy for the

Fishfinder to see a lot of detail. The Fishfinder can indicate many

different kinds of bottom conditions, as shown in Figure 5-12.

A hard bottom appears as a thin line. An uneven bottom which is

covered with rocks or coral produces a complex display; the bottom

image is irregular, with long tails pointing upward. A wreck produces

a similar image.

A softer bottom or a bottom covered with seaweed produces a wide

line, as the sound waves reflect from different layers of the bottom. In

Figure 5-12, the Fishfinder is getting a good echo from the bottom, so

the upper layer of the bottom is shown as dark gray.

Notice that the lower layer of the bottom is shown as a lighter gray,

this indicates a weaker echo. This could mean that the upper layer is

soft; some sound waves may get through this layer and be reflected as

a more solid layer below.

It is also possible that the sound waves are making two complete trips

— hitting the bottom, bouncing off the boat, then reflecting off the

bottom again; this can happen if the water is shallow, the bottom is

hard, or gain is set high.

Selecting the Power Setting

The POWER MODE Functionbar button allows adjustment of the

transducer signal. When AUTO is selected (default), the Fishfinder

automatically determines the power setting based on the current depth.

LO power (10 W) is used in depth ranges less than 20 feet and HI

power (600 or 1000 W, depending on your transducer) is selected for

depths greater than 20 feet. When AUTO is selected the current

automatic power setting is indicated in the top status line by an L

(low) or H (high). If you want to manually adjust the power to suit

current conditions, you can select either LO or HI power. The power

setting is retained when the unit is powered off.

To change the power setting:

1. On the Pathfinder Panel, click MULTI to display the

associated Functionbar buttons.

2. Click Power Mode. A drop-down menu appears.

3. Click to choose between AUTO, LOW, or HIGH power.

The selected setting is highlighted.

4. Click ENTER, CLEAR, or BACK to return to the top-level

Functionbar menu.

Selecting the Frequency

The hsb²Series Fishfinders use dual frequency sonar. The two

frequencies used are 50 kHz and 200 kHz. The Fishfinder

automatically selects the appropriate frequency. Alternatively, you

can manually select either frequency, or both frequencies

simultaneously. Each is suitable for a particular purpose:

50 kHz Frequency – When using this frequency, the transducer scans a

wide area. The 50 kHz signal penetrates water well, and is good for

use in deep water.

200 kHz Frequency – When using this frequency, the transducer scans

a narrower area, but produces a more detailed view. The 200 kHz

signal is good for finding fish near the bottom or close together, and is

better suited for use in shallow water.

Split Frequency – The transducer can operate in both 50 kHz and 200

kHz frequencies at the same time. If you choose split frequency

operation, the scrolling bottom display is split horizontally; the upper

half shows the 200 kHz detailed view and the lower half shows the 50

kHz image. You can also choose the split frequency display with the

Fishfinder display options: Bottom Lock, A-Scope, or Zoom.

To change the frequency:

1. From the Functionbar’s top-level menu, click Frequency.

2. Click 50 KHz, 200 KHz or Split. The scrolling bottom is

displayed in the selected frequency. If you choose split,

the scrolling bottom is dis•played in both frequencies with

200 kHz in the upper and 50 kHz in the lower window.

3. If necessary, click Frequency/Auto to toggle between

automatic and manual frequency selection.

4. Click ENTER, CLEAR, or BACK to return to the top-level

Functionbar menu.

Adjusting Display Gain (Sensitivity)

The Gain, or sensitivity, of the display adjusts background noise by

varying echo strength for display. The value of the GAIN control

determines the strength above which echoes are displayed: If the Gain

is low only the strongest echoes are displayed; as the gain is increased

more, but weaker echoes (from, say air bubbles) are displayed.

The display Gain should be set high enough to see fish and bottom

detail, but without too much background noise. Generally, a high gain

is used in deep/clear water; a low gain in shallow/murky water.

The Fishfinder provides automatic or manual Gain adjustment.

Automatic adjustment is based on depth and water conditions. As

conditions change the auto-gain adjusts to display fish with a

minimum of background noise. You can manually add a bias to the

auto-gain setting. If you select manual adjustment, you will need to

re-adjust the Gain as conditions change.

To adjust the Gain:

1. On the Pathfinder Panel, click GAIN. The Gain function

buttons appear.

2. Click the Gain button for the appropriate frequency:

50KHz or 200KHz.

3. Click the large button to toggle between Auto or Manual

Gain.

4. Click the arrow keys to adjust the level.

Adjusting Color Gain

The Color Gain determines how echoes of different strengths are

displayed. Seven colors per palette are available and the echo strengths

are divided into seven bands to correspond with each shade of color.

The Color Gain control sets the lower limit for the top color band:

All echoes with a signal strength above this value are displayed in the

strongest shade/color. All echoes weaker than this value are divided

equally between the remaining shades/colors.

Setting a low value produces small band for the strongest color, but a

wide signal band for the other colors; setting a high value gives a wide

band for the strongest color, but a small signal band for the other colors.

The Fishfinder also provides automatic or manual Color Gain

adjustment. Automatic adjustment displays colors based on current

conditions, with as many colors as possible, while minimizing noise

and clutter. As conditions change the auto-color gain adjusts. You can

manually add bias to the auto-color gain settings. If you select manual

adjustment, you will need to re-adjust the gain as conditions change.

To adjust the Color Gain:

1. On the Pathfinder Panel, click GAIN.

2. Click the Gain control for the appropriate frequency:

50KHz Color Gain or 200KHz Color Gain.

3. Click the large button to toggle between Auto or Manual Gain.

4. Click the arrow keys to adjust the level.

Using Bottom Lock

The scrolling bottom display provides a top-down view, referenced

from the surface of the water. Bottom Lock shows a water column of

fixed height, referenced from the bottom, that appears flat. It removes

bottom detail to provide an image of objects directly above the bottom,

and is useful when you are looking for fish that feed close to the bottom.

You can select the Bottom Lock image to be vertically split with the

scrolling bottom display, or it can replace the scrolling bottom display.

The bottom is shown as a straight line. Notice that some bottom

features may extend above this line. The actual depth reading is given

in the bottom left hand corner of the Bottom Lock display.

Range intervals on Bottom Lock are measured up from the bottom

(rather than down from the surface). Thus, the bottom is shown as

zero and the top number indicates the maximum distance above the

bottom being displayed. You can adjust the Bottom Lock range.

If the A-Scope or Zoom image is displayed, selecting Bottom Lock

automatically switches off A-Scope or Zoom. If split frequency

selected, the Bottom Lock image is displayed in both frequency

windows. If Target Depth ID is on, the target depth is displayed as

distance from the bottom.

To display the Bottom Lock image:

Using Alarms

The ALARMS Functionbar button is used to set up alarms: three

alarms are available to alert you to the presence of fish, shallow water,

and deep water. Each alarm can be toggled On/Off, and you can set

the depth at which shallow and deep water alarms are triggered

(between the ranges 2–3000 feet/0.5–500 fathoms/1–1000 meters).

You may want to use the shallow and deep water alarms when you are

anchored. Set the limits to just above and below your anchor depth;

the Fishfinder triggers an alarm if the anchor drags and the boats

moves into shallower or deeper water.

· Fish Alarm – If this alarm is On, the unit sounds a buzzer

whenever it finds a fish.

· Shallow water – You set depth at which the shallow water

alarm triggers. When the depth is less than that set, the

buzzer sounds and a pop-up window describing the alarm

is displayed. You cannot set the shallow alarm to be

deeper than the deep alarm.

· Deep water – You set depth at which the deep water alarm

triggers. When the depth is more than that set, the buzzer

sounds and a pop-up window describing the alarm is

displayed. You cannot set the deep alarm to be shallower

than the shallow alarm.

Using Polars to Optimize Your Performance

This section explains how to use Navigator’s Polars plotting

functionality to analyze and fine-tune your boat’s performance.

Intended primarily for the experienced sailor, Polars uses a group

of variables (such as apparent/true/corrected wind angles, boat speed,

heel/pitch, and so forth) to determine what heading you should set

your boat upon to achieve the best possible speed under varying wind

conditions. Analysis results are displayed using several graph plots

and data matrices, which you can modify (edit) to suit your needs.

A typical Polars plot screen is shown in Figure 5-13.

Collecting Data

The accuracy of the analysis presented by Polars depends upon the

volume and accuracy of the data collected. There are two primary

areas within Polars where you can enter and modify data: the Polar

tab and the Data tab (Figure 5-13). The Polar tab displays the Polar

Parameters screen, which contains variables/values used to plot the

Polar graph. The Data tab displays the Data Tests screen, which

enables the input of advanced, boat/weather performance-related

information that you can use to further fine-tune the analysis.

While these screens come pre-loaded with default data, it is essential to

replace as much of this information as possible with real performance/

atmospheric-specific data. You can use Navigator’s DataTrak and Data

Logging utility programs to record a wide variety of performance-

related data that is ideal for use with these secreens. Data for these

screens can also come from such sources as your boat’s manufacturer

and local nautical organizations.

How to Graph and Read a Polar Plot

This section lists the basic steps you must perform to graph and read a

Polar Plot screen (Figures 5-14 and 5-18). The Polar Plot screen

graphs the theoretical headings your boat should take toward specified

targets (both upwind and down) when encountering various wind

conditions. As discussed earlier, the accuracy of these graphs depends

primarily on the volume and accuracy of the boat- and weather-

specific information you’ve entered into the Polar Parameters and

Data Tests screens. After you have entered your data, that information

is displayed as a polar graph in the Polar Plot screen. Placing the

cursor anywhere along the Polar plot yields a small pop-up window

that displays the wind angle/boat speed correlation at that point.

To graph a Polar plot, do the following:

1. Enter all requisite data into the Polar Parameters and Data

Test screens as described in the previous subsections.

2. Click the Polar tab to display the Polar Plot Screen.

3. As shown in Figure 5-18, select the boat speed scale (bottom

axis) you want displayed by clicking on the Boatspeed (kts)

up/down arrows or by entering numbers directly.

4. Select the range of True Wind Speeds to be plotted by

clicking on the Tws (kts) up/down arrows or by entering

numbers directly.

RayTech Navigator User’s Guide

To read a Polar plot, refer to the example in Figure 5-18 and the

following plot component definitions:

· The bottom axis shows boat speed range in knots, with the

minimum/maximum speed and speed interval determined by you,

depending on the scale you want plotted.

· The top axis describes an arc of 180° representing your boat’s

direction with respect to the wind. At 0° you are sailing directly

into the wind, at 180° you are sailing directly with the wind.

· The lines that lie precisely on the 70° and 110° axes (in this

example) correspond to the settings of the Twa1 and Twa2

variables found within the Polar Parameters screen. These lines

are displayed in blue on the screen.

· The lines that diverge between 30° and 50°, and 130° and 160°,

represent the correlation between True Wind Angle (Twa)

upwind and downwind (respectively) and boat speed.

These lines are also displayed in blue on the screen.

· The line that describes a semi-circle (beginning from 0°, 0 Kts

on the example plot) plots the optimum heading and resultant

speed relative to the True Wind Speed (Tws) range you enter at

the bottom of the screen (see Figure 5-18). As you increase

the Tws range, additional lines are plotted onto the graph,

showing the heading you should take to make optimum progress

as wind speed increases. These lines are displayed in black.

· The dot and coordinate-pop-up show the current boat speed and

heading, as entered into the Data Test screen. The dot is

displayed in red, and will only appear if the value entered can

be plotted on the current graph.

The Vmc Plot screen (Figure 5-21) displays the Velocity Made good

on Course toward a specific mark or target. Although similar in

concept to Vmg, Vmc is equal-to Vmg only when the bearing to the

mark and wind direction are identical. Vmc is used when you expect

the wind to change between your present position and the target

(primarily in long course racing). In such an instance, it may be a

smarter tactical move to sail toward your target at the fastest possible

speed, even if that heading isn’t directly toward the target.

To use the Vmc plot, select the Course and True Wind Direction and

True Wind Speed to be plotted by clicking on the Course, Twd, and

Tws up/down arrows or by entering numbers directly. By default,

Course and Twd are initially derived from instrument input, but the

Calibrating to Ensure Data Accuracy

The accuracy of the data generated by your instruments and

performance evaluation systems depends on accurate calibration.

While the following subsection presents an introductory explanation

of instrument calibration, you must refer to the manuals that came with

your instrumentation systems for the specific calibration procedures.

The subsections that follow explain the calibration methodologies for

the following variables:

Boat speed

Compass

Apparent wind angle

True wind angle

True wind speed

Boat Speed Calibration

Boat speed calibrations are entered directly into your instrumentation

system (refer to your system’s manual for the procedure). While it

may not be practical to check boat speed calibration on a daily basis,

we encourage you to check this variable on a measured mile as often

as possible, as the paddle-wheel impellers that generate boat speed

data can change their physical characteristics markedly over their

lifespan due to the environment in which they operate. When making

a measured mile calibration, perform three consecutive runs over the

known distance, to eliminate any tidal current effects.

RayTech Navigator User’s Guide

Compass Calibration

Compass calibration involves two procedures: Deviation and Heading

Error calibration. Calibrating Deviation corrects compass error around

the different points of the compass. Keep in mind that some instru-

mentation systems have the ability to swing (calibrate) the compass

automatically.

Heading Error calibration ensures that the heading the compass

indicates always reflects your true heading. Calibration of this kind is

usually achieved by piloting the boat along a known line of transit.

For best results, you should have your compass professionally swung.

Apparent Wind Angle Calibration

You must perform Apparent Wind Angle calibration after the mast

head wand is initially installed on your boat. Since the wand may not

lie exactly on the fore and aft line of the boat, Awa calibration is

necessary to compensate for this. The Awa should read zero when the

vane is on the centerline of the boat. If you don’t get a zero reading,

you must enter an offset value into the instrumentation system.

The amount of Awa alignment error can be established in two ways:

Take the boat head-to-wind and read the Awa angle. If the

Awa value is not zero, you have a calibration error. This

method is less accurate than the following one.

Perform two or three tacks upwind in even wind strength,

then compare the average Awa tack-to-tack by using

Navigator’s DataTrak utility.

The calibration must be performed under even wind strength, as

differing wind strengths will result in different Awa readings tack-to-

tack. It is also important to calibrate Awa offset in the absence of

wind shear and wind gradient; however, calibration in light air (such

as a sea breeze filling in) is not recommended.

5-66

Download from Www.Somanuals.com. All Manuals Search And Download.

Advanced Navigator Functions

Here are some important guidelines for successful Awa offset

calibration:

Choose a day with no wind shear, minimal gradient, and a

steady True Wind Speed.

Ensure that Navigator’s DataTrak utility is online and

operational.

Sail upwind at your optimum close-hauled angle.

Complete four to six tacks in steady wind conditions.

Use the “wand method” of averaging in the charts to ascertain

the difference in Awa on each tack.

Once you have determined the Awa offset, enter it into the Mast head

Unit offset parameter within your instrumentation system. Use half the

difference between the wind angle on each tack. This keeps the Awa

symmetrical tack-to-tack, because Laylines are predicted based upon the

Awa.

True Wind Angle Calibration

True Wind Angle must be calibrated because of the way

instrumentation systems measure Awa. Since Awa is measured

relative to the top of the mast, errors can be introduced by the mast-top

twisting under various wind conditions as a result of mainsheet,

topmast, and runner loads. Awa calculation accuracy is also affected

by air flow over the sails (and would be entirely different in the

absence of sails) and by wind shear as discussed in the previous

subsection.

To calibrate Twa, begin by performing at least six tacks/gybes each

day to correct for Twa and Twd. The simplest way to arrive at a value

is to watch the Twd before and after a tack, halve the difference, then

add or subtract this value to/from the wind correction table for that

wind strength. You can use the Twa Corrections screen (Figure 5-22)

within Polars to keep track of these corrections.

5-67

Download from Www.Somanuals.com. All Manuals Search And Download.

RayTech Navigator User’s Guide

Figure 5-22. Twa Corrections Screen

It’s important to note that depending on your instrumentation system’s

damping, the Twa value can take up to 30 seconds to “settle down”

after a tack/gybe. Whether you add or subtract the value depends

upon whether the instruments have either lifted or headed during the

tack. The same convention applies to a downwind gybe, whereby a

lift takes you away from, and a header takes you closer to, the bottom

mark. If you apparently get a lift after tacking, you must subtract that

correction and add a header correction to the table.

Here’s an example of Twa calibration:

After tacking five times, the average wind direction changes 6 degrees

tack-to-tack in 10 knots of wind. This has the effect of showing a lift

and therefore 3 degrees can be subtracted from the upwind correction

table for 10 knots of wind. Keep in mind that some tacks/gybes can

yield an incorrect calibration value if the wind has actually shifted, so

this must also be factored into the calculation process. Additionally,

calculations will be affected if the boat has been set up differently

tack-to-tack (such as varying runner loads, more backstay, etc).

True Wind Speed Calibration

True Wind Speed calibration assumes that the True Wind Speed

upwind reflects the correct value. However, when sailing downwind,

airflow over the masthead unit is affected by the spinnaker. Therefore,

downwind Tws must be corrected so that your instruments show the

same Tws value upwind and down.

The simplest method to achieve this is to measure wind speed upwind

and then calculate an average using the wand method. Once the

spinnaker is up and the boat is stable downwind, take another wand

method reading and average it. The difference between the two

values is the correction to be subtracted in the Tws Corrections

screen (Figure 5-23). Enter your corrections into the 180° column

for the wind speed you are experiencing.

Basic NMEA and RS-232 Cabling Principles

This section explains some of the basic principles involved with

National Marine Electronics Association (NMEA) and RS-232

electrical connections. Knowledge of this information is not required

to connect Navigator to the various peripheral devices; however, it is

provided for the advanced user as pertinent technical background.

NMEA Basics

Most marine electronic devices that output data do so over NMEA

ports. NMEA ports are known as a “balanced pair,” which means that

the data signal is carried over two wires (via an RS-422 electrical

layer, in computer/datacom terminology). The signal level is

determined by calculating the voltage difference between the two

wires, hence the NMEA output signal is called a Differential Data

Signal (not to be confused with Differential GPS, which is a GPS

system error correction method).

Differential Data Signals are designed to be error-resistant by keeping

the positive and negative leads close together for the entire cable run.

This means that they both pick up the same levels of noise, which is

ultimately subtracted from the signal, preserving the signal’s data

integrity. NMEA ports typically have four connections (two for each

lead): Transmit (positive/negative) and Receive (positive/negative).

Some devices may use a single-direction port, meaning that they can

transmit or receive only.

When connecting one NMEA device to another:

1. Connect Device A’s positive Transmit (Tx+) lead to

Device B’s positive Receive (Rx+) lead.

2. Connect Device A’s negative Transmit (Tx-) lead to

Device B’s negative Receive (Rx-) lead.

A-12

Download from Www.Somanuals.com. All Manuals Search And Download.

Appendix A – Connecting Peripheral Instruments

Important: when performing the above connection, be sure you

connect the devices directly; do not use the vessel’s DC ground circuit

to carry the Transmit (negative) signal. You may encounter devices

that do not properly implement the NMEA specification, and share

their Transmit (negative) lead with the device’s DC power ground

circuit. In this case, you must still run a cable directly between the

Transmit (negative) and Receive (negative) leads as previously stated

— do not share the DC power ground circuit.

RS-232 Basics

Most desktop and laptop computers have RS-232 ports. An RS-232

port uses a 3-wire interface, in which the transmit and receive leads

reference the same signal ground. It is important not to confuse the

RS-232 cable’s signal ground with the vessel’s power ground circuit.

While the vessel’s power ground may coincidentally be at the same

level as the RS-232 signal ground, there is no industry standard that

requires this. Since the RS-232 transmit and receive data signals

reference a common signal ground to maintain their integrity,

you must connect the signal ground circuit directly between the

two RS-232-linked devices.

To wire an RS-232 device to another RS-232 device, connect:

1. Device A’s Tx lead to Device B’s Rx lead.

2. Device A’s Rx lead to Device B’s Tx lead.

3. Device A’s Signal Ground (SGnd) lead to Device B’s

SGnd lead.

RS-232 uses a common ground, which differs in electrical

specification from the NMEA’s transmit/receive-pair arrangement.

Because of these signal level differences, the way you interconnect

an RS-232 device and an NMEA device varies with the application.

Note: You may also encounter voltage differences

when interconnecting older RS-232/NMEA

hardware - use care.

Device’s Rx+ lead.

2. Connect the RS-232 Device’s SGnd lead to the NMEA

Device’s Rx- lead.

To wire an RS-232 device to receive input from an NMEA device:

2. Connect the RS-232 Device’s Rx lead to the NMEA

Device’s Tx+ lead.

3. Connect the RS-232 Device’s SGnd lead to the NMEA

Device’s Tx- and Rx- leads.

There are some infrequent cases where binding the NMEA device’s

Tx- and Rx- leads together may cause difficulties. If you do encounter

problems, you’ll need to use an RS-232-to-NMEA converter between

the two devices. A converter is typically required very rarely (in less

than 1% of applications; however, the modern Furuno radar systems,

for example, do require them), but is still a good place to begin trouble-

shooting if problems arise with the RS-232/NMEA interconnection.

Appendix A – Connecting Peripheral Instruments

Circuit Grounding Issues

By far the most important issue in electrical connections is proper

circuit grounding. In addition to all the other electrical gremlins that

poor grounding gives rise to, instrument signals are easily scrambled

if they are badly grounded, resulting in erratic and unreliable displays.

Installations with both AC and DC current have separate ground

circuits for each. In such cases, the use checklist that follows to

ensure that the AC and DC ground circuits are kept fully isolated:

þ Use isolating transformers or a separate power-inverter to

run PC, monitors, and other sensitive electronic instruments

or devices.

þ Use an isolating transformer with weather FAX audio cables.

þ Use an RS-232/NMEA converter with optical isolation on

the signal lines.

þ Use PCs and other devices that are directly DC powered.

Proper Cable Shielding

For all but the shortest length cable runs, data cables must be shielded

to prevent them from picking up electrical noise from other devices

and to keep them from radiating potential interference. If you

encounter a data corruption problem, a good place to begin trouble-

shooting is with the cable’s shielding, especially on longer runs.

Make sure the cable’s shielding hasn’t been scrapped off by being

squeezed through a tight area.

Preventing Interference and Crosstalk

You should always run data cables as isolated as possible, and as far

away from high current carrying AC and DC power lines and antennas

as possible. While it may be convenient, bundling power and data

cables together causes crosstalk between them, resulting in scrambled

and unusable data. If you must cross power cables when running data

cables, try to make the crossing as close to 90° as possible; never run

power and data cables parallel within the same bundle. If you have

long runs planned for your data cables, and are using NMEA equip-

ment, use shielded twisted-pair cable to eliminate the danger of

interference and crosstalk.

Charting Enhancements

C-Map Chart Server/Client

With V4.1, RayTech can be a server or client of C-Map cartography

transmitted over the hsb²network. As part of a hsb²network, RayTech is

capable of serving C-Map cartography stored on the PC or read from a C-

Map NT card reader. In this same configuration, RayTech can be a client of

C-Map cartography served from Raymarine hsb²chart plotters.

To use this feature, the RayTech PC must be connected to the hsb²network

via the RayTech hsb²PC kit (Raymarine part number E80019).

Quilting On/Off

With Quilting off, only the chart that is in focus is displayed. When you get to

theedge ofthe chart, you see its border. When you turn on Quilting, allquilted

charts are viewable in that chart window. Chart borders are not displayed;

when you pan to a chart’s edge, RayTech transitions to the next chart.

RayTech V4.1 features additional mechanisms for controlling quilting. In

the Chart Info dialog, there is acheckboxforincludinga chart inthe quilt and

a button for displaying a chart alone. In the Chart Layers Toolbar is a new

Quilting button for turning the feature on and off.

New Databoxes

Databoxdisplaysenableyoutoplacevitalnavigationdatawhereyouwantit.

The databoxes can be customized for content, size, color, position, and font,

ensuring a bright, clear view.

New to RayTech V4.1 are additional databox radar channels for MARPA,

VRM, EBL, radar bearing/range and radar cursor latitude/longitude.

Position Reporting

New in RayTech Navigator 4.1 is the capability to send and receive

automated vessel position reports. The position reports are compiled on a

user-selectabletimeintervalandareautomaticallydepositedintoyourMAPI

compliant e-mail client (such as Microsoft Outlook, Outlook Express) for

transmission by cellular, satellite or SSB e-mail. Upon delivery to the

recipient, the position report can be automatically decoded and plotted on

any other PC running RayTech Navigator 4.1. Over time, RayTech

Navigator will develop a plot right on screen of where the vessel has been.

This feature is particularly useful to the offshore cruiser, racer, fishermen, or

anyone who wants to easily and effectively communicate their vessels

position to other boaters, to friends and family at home, or to a race safety

committee. RayTech 4.1’s position reporting is the backbone of the vessel

reporting system for the 2002-2003 Around Alone offshore sailing race.

Position reporting works in conjunction with RayTech’s automated

weather services.

Raymarine Interim Sheet

➤

To set up your position report:

1. Click on the File menu and select Get Weather from the Internet.

The RayTech Internet Weather window appears.

2. Click the Advanced button of the E-Mail Request tab to set up position

reporting and advanced weather services.

3. Find the Automatic Position Report section under advanced setup.

4. In the Send To field, enter the address to which you would like the posi-

tion report sent. If there is more than one address you want to send to,

enter all of them, separated by commas.

5. In the Frequency drop down box, select how often a position report will

be sent. Standard intervals range between 1 and 24 hours.

6. In the Boat name field, enter the name, call sign, or other identification

for your vessel.

7. Send a position report immediately by clicking the Send Now button.

For the automated position (and weather) functions to operate, you leave the

Internet Weather application and your e-mail client open. At the interval

specified, a newposition report is generated, and passedtothe e-mail client’s

outbox for transmission.

If your e-mail system is not automatic, the position report will remain in the

outbox until you reconnect to your e-mail. At that time, any outgoing traffic

is sent and any incoming reports or weather files are received.

Auto Processing of Incoming Position Reports and Weather

RayTechNavigator4.1canautomaticallyprocess, decodeandplotincoming

position reports and GRIB weather overlays from your e-mail inbox. To do

this, you must make sure the RayTech Internet Weather application and your

e-mail client are running.

It may be beneficial to add shortcuts to the weather and e-mail programs to

your Windows ‘Startup’ group, ensuring that they run every time the PC is

rebooted. The setup for this feature is located within the Advanced weather

dialog, outlined in the preceding section Position Reporting.

To schedule RayTech to automatically check the e-mail inbox for new

message traffic, specify a time interval in the Frequency drop-box, located

under the Automatically Send Files section.

Other Vessel Tracking

The Other Vessel Tracking feature has been enhanced to enable you to delete

the scheduleofanytrackedvessel andfilterentriesby boat nameand by time.

Raymarine Interim Sheet

Other Vessel Tracking works in conjunction with the Position Reporting

system, enabling the navigator or racer to monitor the positions of other

vessels traveling in company or under race conditions. It is accessed by

clicking on the Tools menu and selecting Other Vessel Tracking.

DataTrak Enhancements

The DataTrak module is a time-based, graphical recording system included

with RayTech Sail Racer and RayTech Fishing Pro Suites. DataTrak script

charts can be resized to fixed time intervals for quick data capture. This is

invaluable to the navigator in capturing data for target and polar calculations

or trying to ascertain minute changes in any recorded variable overtime.

Navigator 4.1 now allows for the display of DataTrak wand times. When

capturing data from the DataTrak, vertical frames can be inserted in the chart

delineating start and end points for the data capture. These lines, called

wands, represent a particular segment of time on the graph. The time interval

is reported at the top of the graph, in the blue status bar.

Animation Enhancements

When displaying weather layers on the chart you can animate the

informationtoviewweatherchangesovertime. Toanimate thisdata, display
