I started playing around with the calculator to see how to improve the capsize results for the M-15. http://www.image-ination.com/sailcalc.html Sail area, LWL, LOA had minimal affect on the results. Displacement had some influence. More was better. Beam had a big impact. However, smaller was better. It seems a lead canoe would prevent capsize. Steve R. M-15 #119 Lexington, KY
