Dear All,
for a sailboat wind instrument it is known that heel narrows measured apparent wind angle by 1 /Cos(Heel).
Upwind, with a 30º heel, apparent wind AWA is narrowed about 3.5º or 13%.
Since there is no mention of this fact anywhere in the docs
Nor in the excellent summary here:
http://forum.raymarine.com/showthread.php?tid=987
I wanted to know assuming there is a heel angle provider on the nmea2000 bus would the I70s compensate/account for it?
What is Raymarine strategy to calculate polar and performance in presence of this parameter.
