3 Navigation: Chart

The chart window shows the chart, the boat’s position course and navigation data.

3-1 Introduction to navigating

The 657 has two ways of navigating, going straight to a point or following a route.

3-1-1 Navigating to a point

When the 657 is navigating to a point, the chart and highway displays show navigation data:

AThe boat position .

BThe destination point marked with a circle. C The boat’s plotted course to the destination.

DTwo CDI lines, parallel to the boat’s plotted course, which indicate the maximum expected deviation from the plotted course.

D

C

AD

For more information, see appendix C.

If the 657 is connected to an autopilot, the 657 will send data to the autopilot to steer the boat to the destination. Start the autopilot before starting to navigate to the point.

If the 657 has no autopilot, steer the boat manually:

ause the boat position and destination on the chart or highway displays

bor use navigation data displayed on the data header (see section 2-7-3)

cor use COG and BRG on the compass (see section 2-7-4).

Note:

1If the XTE alarm is enabled, an alarm will sound if the boat deviates too much from its intended course (see section 17-9).

2If the arrival radius alarm is enabled, then an alarm will sound to show that the boat has reached the destination (see section 17-9).

3-1-2 Going to a waypoint or to a point on the chart

A waypoint is a position that you can set on the 657 chart, for example a fishing spot or a point on a route (see section 5).

Going to a waypoint from the chart window

1Go to the chart window.

2Move the cursor to the waypoint:

either use the cursor keys or use Find (see section 3-2-5).

3Press and select Goto.

Going to a waypoint from the waypoints window

1Go to the waypoints window.

2Press or to highlight the waypoint to goto.

3Press and select Goto.

Going to a point on the chart

1Switch to a chart window.

2Move the cursor to the destination point: either use the cursor keys or use Find (see section 3-2-5).

! WARNING

Make sure the course does not pass over land or dangerous waters.

3Press and select Goto cursor.

Navigating

The 657 navigates to the point as described in section 3-1-1.

Cancelling navigating

Go to a Chart window, press and select Cancel goto.

Tip: Before starting, create waypoints at points of interest. Create a waypoint at the start of the trip for you to navigate back to (see section 5-2-1).
