Boat length and solo sailing
When you say,"Boats with heavier displacement but still higher performance numbers for SA/D were of personal interest: Dufour 31,Islander 32, Island Packet32, Morgan 324, plus Ericson32 and Sabre 34."
I have to question your idea that this group represents "still higher performance number". Some do and some don''t. For example, I want to point out that Island Packet in particular publishes sail area numbers that are not consistent with the usual practice for calculating sail area. The normal published sail area and the area that is used by convention to calculate SA/D is the 100% foretriangle. Island Packet uses the sail area of their genoa. This results in an artifically high published SA/D.
