Wind Offset
Note ! This offset only applies if you have a wind transducer directly connected to SimNet (IS12TW) or a wind transducer that outputs data on NMEA2000 format.
The Wind Offset feature allows you to correct for a fixed wind angle offset. Steer the boat directly into the wind with a damping of 15s. Keep the bow a steady heading for
The Offset value can be either positive or negative.
Wind damping
Damping of the apparent wind angle is made by the Advanced Wind Filter (AWF) in the Autopilot Computer.
The inputs to the AWF are heading, boat speed, apparent wind angle and wind speed. Verify that these inputs are available in User Setup/Source Select.
Heading sensors, speed sensors and wind sensors have variable performance. The measured wind angle can be very erratic when the boat is rolling heavily. In such conditions the AWF gives a better result when the calculations are based more on heading and boat speed inputs to achieve the correct apparent wind angle. Increasing the ‘Wind damping’, will make the AWF depend more on heading and boat speed to calculate the correct apparent wind angle. Decreasing the ‘Wind damping’, will make the AWF depend more on the “raw” apparent wind angle data.
The boat speed input to the AWF is primarily Speed Over Ground (SOG). If this is not available, the AWF will use speed through water. If none of these are available, the AWF will use a boat speed that is 1.5 times the the Transition Speed set in the Installation/Seatrial menu.
