4.1 Registering Waypoints
In navigation terminology a waypoint is a
particular location on a voyage whether it be
a starting, intermediate or destination
waypoint.
The GP-150 can store 999 waypoints,
numbered from 001-999. Waypoints can be
registered four ways:
• by cursor
• by MOB position or event position
• at own ship's position
• by range and bearing from position, and
• through the waypoint list.
Registering waypoints by the cursor
1) Press the WPT RTE key. The
Waypoint/Route menu appears.

3) Press the cursor pad to place the cursor
on the location desired for the waypoint.
4) Press the NU/CU ENT key.
A window similar to the one shown in
Figure 4-3 appears. The waypoint's
position and date and time registered
appear on the first and second lines.
Waypoints are automatically given the
youngest empty waypoint number and
this number appears on the third line.
You may, however, assign a different
number. If the waypoint shares the same
position with a mark, the mark's position
and date and time entered are registered
as waypoint data.
If the waypoint memory is full, the
waypoint number line in the window is
blank. In this case waypoints cannot be
entered unless a waypoint is written over
or deleted.
To assign waypoint number, go to step 5.
If you do not want to change the
waypoint number, go to step 6 to select
mark shape and enter comment.
