3.3.2 Apparent Wind Angle Calibration (AWA)
To discover the AWA alignment error we can employ one of two techniques.
The first is simply to go head to wind and read the value of the Apparent
Wind Angle. If it reads anything other than 0, you have an error. For example,
if the Apparent Wind Angle reads 4° then you should enter -4 as the
calibration value. If it is less than 0 then the opposite applies.
The second method involves a sailing trial as shown in Fig 3.2 - Masthead
Unit Alignment.

(1) Whilst monitoring APP W/A on a display, sail upwind at the
optimum close hauled angle.
(2) When conditions are steady, write down the mean APP W/A
reading.
(3) Tack the vessel and sail at the optimum close haul position as
before.
