Forces on sails (3 m) = 5-m/s (≈10-knot) wind at 3 m above the water would be approximately "V" (15 m) = 6 m/s (≈12 knots) at 15 m above the water. In hurricane-force winds with "V" (3 m) = 40-m/s (≈78 knots) the speed at 15 m would be "V" (15 m) = 49 m/s (≈95 knots) with "p" = 0.128. This suggests that sails that reach higher above the surface can be subject to stronger wind forces that move the centre of effort ("CE" ) higher above the surface and increase the heeling moment. Additionally, apparent wind direction moves aft with
Sixty Sails Handicap Sixty Sails Handicap The Sixty Sails Handicap is an American Thoroughbred horse race held annually during the third week of April at Hawthorne Race Course in Stickney/Cicero, Illinois. A Grade III event open to Fillies and Mares, age three and older, it is contested on dirt at a distance of one mile and one eighth (9 furlongs).

Since inception, the Sixty Sails Handicap has been
