??C30 Points of sail, trim and tuning??
Ahoy, boardroom. It sounds like you equate heeling with speed. It is an illusion. A boat sails faster and better on her feet. Twenty knots of wind is a lot. Remember that the pressure on the sails increases as the square of the wind speed. That is, if the wind speed doubles, the pressure quadruples. At 20 knots you should have a jib up, not a genoa, and should be reefed. It helps to visualize what is happening and to understand the forces acting on your boat conceptually instead of academically. If you don''t mind doing some reading, I have several discussions on the board that will help you understand balance, heeling, sail trim etc. in a visual way. Look back and find the following discussions:
Under Learning To Sail, Aerodynamics of Sailing, Feb. 10, dhartdallas, Pt.1 and Pt 2.
Under Learning To Sail, Heeling Paranoia, Jul. 29, 4:24 PM, and Aug.28,4:21 AM.
Under Learning To Sail, Sail Trim For Beginners, Jul. 23, l:04 AM, and Dec. 12, 4:26PM.
Under General Discussion, Mast Rake For Cape Dory 30, Jul. 31, 12:59 AM.
You have two fundamental problems. You are over canvassed, and you are sheeting in too hard. These discussions will help you.
