Chapter 2: Using the Wheel Pilot 19

2 Using the Wheel Pilot

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 wheel 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
