autopilot. The autopilot will utilize the current wind
direction in these calculations and the change of course is
accepted by pressing the
softkey [2].
Operating in WIND
NAV
mode
Refer to
Figure 1-2 which shows a scenario with a sailboat
that enters Wind
NAV
mode to sail the most efficient way to
waypoint WP1.
1. The autopilot is still in Wind mode approaching mark
2 and waypoint WP1 has been entered on the chart
plotter.
2. The Wind
NAV
mode is entered and the autopilot
prompts confirmation for a course change of 71
degrees to starboard.
3. The boat is now on the leg to mark 4 where a
starboard tack is required to avoid running on
ground. The distance to tack DTT is displayed and so
is VMG to wind. Furthermore the autopilot displays
course to steer and heading.
4. The tack has been initiated on the autopilot and the
tack display is presented.
5. The autopilot now presents you with information
about the new leg and the next tack.
6. You are about to cross the layline and the autopilot
“recommends” a new tack to Port.
7. The new tack is performed.
8. You are on the last leg directly to the waypoint. The
autopilot is now keeping the boat on track (XTE) and
displays bearing and distance to the waypoint.
