Adjusting apparent wind speed

Adjusting the Apparent Wind Speed (AWS) reading compensates for any small errors which may exist in the apparent wind speed reading.

Prerequisites:

  • To apply an offset to your AWS readings an accurate reference for AWS must be used to compare the instrument’s AWS reading against.

  • Conditions should be calm (i.e. a slight sea) and a steady breeze. Try to ensure the vessel is not rolling or pitching too much.
