The offset value to be entered should represent the distance between the face of the depth
transducer, and the lowest part of the boat below the waterline, or the distance between the
face of the depth transducer and the water surface.
Sea Temperature
If a suitable temperature sensor is fitted, the system will monitor the current sea temperature.
The offset value to be entered should adjust the temperature reading from the sensor to
match a calibrated thermometer when submersed in the water
Apparent Wind
This provides an offset calibration in degrees to compensate for any mechanical misalignment
between the masthead unit and the center line of the vessel.
To check the masthead unit alignment error we recommend you use the following method
which involves a sailing trial.
Sail on a starboard tack on a close hauled course and record the wind angle, then repeat the
process on a port tack. Divide the difference between the two recorded numbers and enter
this as the wind angle offset.
33º 27º
WIND
Starboard Tack Port Tack
Starboard tack = 33º
Port tack = 27º
Difference: 33º - 27º = 6º
Offset: 6º/2 = -3º
If the starboard apparent wind angle is greater than the port angle then divide the difference
by 2 and enter this as a negative offset. If the port angle is greater than the starboard then
divide the difference by 2 and enter this as a positive offset.
