• mast length is 12.5m

I'm not entirely certain I've put in the correct numbers for all the calculations correctly, but here are our general performance & stability numbers (from sailingcourse.com):

• The maximum speed of the boat is: 6.29 knots (22ft. at water line)
• The Sail Area Displacement Ratio is: 15.57. The sailboat is a cruiser-racer.
• The Displacement to Length Ratio is: 332.75. The sailboat is a heavy displacement cruiser.
• The Motion Comfort Ratio is: 27.68
• The Stability of the boat is: 1.74 (Stability is predicted !!) (anything less than 2 is considered stable)
• The screening stability value of the boat is: 14.81
• Angle of Vanishing Stability is 193.09 (estimated a 0.7m draft of hull without keel, will try to measure this season) (anything above 120 is good, above 140 is better)
• Ballast Displacement Ratio: %44
