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 possible 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

Returning to Auto from Track mode

To return to Auto mode from Track mode:

press auto, or

press -10and +10 together.

Cross track error (XTE)

Cross track error (XTE) is the distance between your current position and the planned route. This is displayed in nautical miles (nm) and is taken directly from your navigator.
