sail light, powerful boats
General racing trend is toward relatively lighter and faster boats with bigger kites. So, try to sail lighter more high horsepower boats to get a feel for how these go. In small boats try 505, 49er, Int. 14, google them for class/fleet sites. in bigger boats try Melges 24, melges 32, Mumm 30 etc. Buy/borrow/steal a copy of Frank Bethwaite's book High performance Sailing. Read "Sailing Anarchy" website. Go to the 3 closest sail lofts, give them your info, tell them you are ALWAYS available for sail testing on race boats, any weather, any time. Your phone will ring.
Be the first guy to the boat on race days. Clean stuff. be the last guy to go home. Clean stuff.
Never ever give up.
