40 | Operation

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.
