Mast angle
Mast Angle measurement is required for yachts with rotating masts as the wind sensor rotates
with the rig, which introduces errors into the wind calculations. To correct for this issue a mast
rotation sensor is fi tted to the system, which provides the angle information.
When Mast Angle data is available all wind data is corrected to ensure that all angles are
relative to the bow of the boat. In addition a new function, Wind Angle to Mast, is created.

Measured wind angle
Measured Wind Angle is the angle measured by the masthead unit, no calibrations are
applied except the basic off set value for alignment.
Measured Wind is not used whilst sailing, but is a useful function for checking the operation
and alignment of the wind instruments before additional corrections are applied to the data
during the calculation of the True Wind and Apparent Wind.

Measured Wind Speed is the wind speed measured by the masthead unit, no calibrations
are applied except the factory set off set and Hz/Kt values. Measured Wind is not used whilst
sailing, but is a useful function for checking the operation of the wind instruments before
additional corrections are applied to the data during the calculation of the True Wind and
Apparent Wind.
