...if you do not change the position of the sail.
as weatherhelm is not a direct result of aspect ratio but of a poor
balance between CE and CLR I'd say.
with running luff parrels you can move your sail back and forth on your
mast for minor adjustments. if that's not sufficient, you'll have to
move your mast. or maybe you can make changes to the lateral plan of
do you have a drawing of your boat somewhere we can look at? so one can
see the position of the CLR etc. ?
