The gybe prevent function will be activated when the measured
apparent wind angle becomes greater than 175° or when the
wind angle gets opposite to the set wind angle. Additional rudder
will be commanded to keep the wind on the same side as the set
wind angle.
Caution ! The tack and gybe prevent functions are not a guarantee
against getting into a hazardous situation. If the effect of the
rudder and/or drive unit is not adequate, it may happen. Pay
particular attention in such situations.
2.19 Wind steering and navigation
The autopilot can also steer the boat given both wind data and
track data from a GPS/Chartplotter. In this mode called
WIND
NAV
mode the automatic steering is based on a set of
criteria (see bullets below). Wind steering and navigation is
activated by pressing the NAV/WIND/SETUP button when in
Wind mode. There are two sub-modes under this key: NORMAL
(default) and RACING (see below). The initial course change
(CHG) needed to navigate towards the active waypoint, is
calculated by the autopilot. The autopilot will maintain windside
in these calculations and the change of course is accepted by
pressing the PORT or STBD button [1].
