gets opposite to the set wind angle. More rudder will be
commanded to prevent an unwanted gybe.
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.
1.9 Wind steering and navigation
(sailboats)
The autopilot can also steer the boat given both wind
data and track data from a GPS/chart plotter. In this
mode called WIND
NAV
mode the automatic steering is
based on a set of criteria (see below). Wind steering and
navigation is activated by pressing the NAV key when in
Wind mode [1]. The initial course change (CHG) needed
to navigate towards the active waypoint, is calculated by
the autopilot. The autopilot will utilize the current wind
direction in these calculations and the change of course is
accepted by pressing the
softkey [2].
