with the luff and foot spars at roughly 13'8" each , the leech could not be over 12'2.52" in order for the sunfish sail to have an area of 75 square feet, unless the area of a triangle is no longer 1/2 bh (base x heighth). Most of the diagrams of the sunfish sail show the leech to be about 1.08 (x) the length of the foot(or luff, being the same),for a length of 14.76', which would put the actual area of a sail at around 84.94 sq.ft. My question i guess would be: is the calculation for the sunfish sail area determined by some new math?
