Corsair 760 Speed Polar

Not an F-24 (a bit faster), but relatable. [Note. This was generated by a velocity prediction program, not testing, so that is that. Typically, they are optimistic, assuming flat water, perfect sails, an empty boat, and glass-smooth hull with no anti-fouling paint. You can subtract 0.5-1 knots, depending on the point of sail, although I've been very close to this.]
