The CE of the sailpan is the center of its area point
on most standard type sails take a point from the tack and clew up diagonally 2 /3 of the way up on the luff and leach ,---where they intersect is close to the CE -


Darryl / Carl,

Virtually all designers use the centroid (center of area) as the CE. Since in a beach cat the sails work as arfoils in a laminar flow almost all the time, I imagine that a more precise position of the CE could be calculated using airfoil theory, like when designing a wing.

Likewise, since the CLR position is important mostly when the underwater shape is working as a foil, it is also not exactly in the centroid and could be calculated more or less the same way.

Do you think this is wrong or only too complicated for practical puroses?

Thanks,


Luiz
