Simrad AP26, AP27 manual Wind steering and navigation

Installation

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.

2.19Wind 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

WINDNAV 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].
