Manual track acquisition
If your navigator only provides cross track error information, you must acquire the
track manually:
1. Steer the boat to within 0.1 nm of track.
2. Bring the heading to within 5° of the bearing to the next waypoint.
3. Press
auto
.
4. Press
-10
and
+10
together to enter Track mode:
• the autopilot will start tracking to the waypoint
• the display will alternate between cross track error and the locked pilot
heading
Manual track acquisition at low speeds
Using manual acquisition at low speeds requires additional care as tidal streams
have a far more significant effect at lower speeds than at higher speeds.
In general terms, if the tidal flow is less than 35% of the boat’s speed, you will not
notice any difference in the tiller pilot’s performance in Track mode. However, you
should take extra care during manual acquisition, as follows:
• before you select Track mode, make sure that the boat is as close as possible
to track, and that the direction made good over the ground is as close as pos-
sible to the direction of the next waypoint
• positive checks of the boat’s position at regular intervals are vital, especially if
you are close to potential navigational hazards
