John,
I live in Greenville, SC and sail mostly competively all over the U.S. east of the Mississippi (Key Largo to Sandusky, OH). I sail about 12-16 regattas a year where I now race a Nacra 6.0NA (soon to be the New England chute configuration following ratification of the proposed class modifications). I also own a Nacra 5.2 and I keep a Hobie 18 on Folly Beach, SC for recreational sailing.
I would be glad to help you set up a database form on a website that people could log in this information to be systematically recorded. I should own a website capable of hosting that form in about two or three months.
