I could never live with 14.9. B/D is .29. Sweet motion, but that explains why SA/D ratio is only 14.9. Give her a tad more ballast, put the ballast deeper, and then make the rig bigger. Of course, then you would have something similar to my boat. . . . "Sail Area/Wetted Surface 1.85" IIRC, the Pardeys recommend something close to 2. OTOH, I think they use all sail area and not just 100% triangle. Been awhile since I read their stuff.
