Sea state filter
The Sea state filter is used to reduce rudder activity and autopilot
sensitivity in rough weather. Setting options are:
•
OFF
Seastate filter is disabled. This is the default setting.
•
AUTO
Reduces rudder activity and autopilot sensitivity in rough
weather by an adaptive process. The AUTO setting is
recommended if you want to use the seastate filter.
•
MANUAL
Linked to the steering response control settings described
previously. It may be used to manually find the optimum
combination of course keeping and low rudder activity in rough
but steady sea conditions.
Sailing parameters
Ú
Note:
Sailing parameter settings are only available if the boat
type is set to Sail in the Autopilot Commissioning dialog.
Tack time
When performing a tack in WIND mode, the rate of turn (tack time)
can be adjusted. This gives single-handed sailors time to handle the
boat and the sails during a tack.
A turn performed without shifting wind side, is also made at a
controlled turn rate.
Tack angle
This value is used to preset the course change used when tacking in
AUTO mode. By pressing the port and starboard indicators in the
autopilot pop-up the course changes as much as this value.
Wind function
With wind function set to AUTO, the autopilot automatically selects
between apparent and true wind steering. AUTO is default and
recommended for cruising.
When the boat is running, it is also surfing on the waves. This may
lead to significant changes in boat speed, and thereby also changes
in apparent wind angle. True wind steering is therefore used when
running, while steering to apparent wind is used when beating or
reaching.
