On a calm day with the boat lying at slack warps in the
dock, head to wind, all the gear stowed in its normal place,
and anyone onboard standing on the centreline the heel
angle should be recorded, under these conditions it should
be zero, any error can be taken out by the heel angle
calibration, by adding or subtracting the error from the
existing calibration.
Heel angle calibration is to be found in the system menu

3.6.2 Leeway
Calibrating leeway is a notoriously difficult thing to do; it
may be easier, and as accurate, to consult the yachts
designer who may have a theoretical value for leeway
coefficient, as it is to try to measure it. Should that not be
possible then we can calculate the Leeway coefficient from
the following formula:
L = K x H
Bs x Bs
where, Bs = Boat Speed
K = Leeway Coefficient
H = Heel Angle
L = Leeway Angle
K then is the constant that needs to be entered, and to
establish a value for leeway coefficient we need to measure
the leeway angle at a particular heel angle and boat speed
shown in Fig 13 below.
