The EC-12 would be the way to go if you want to race. They recently had their big regatta in Lawrenceville (April 16-17), and you are in the PRIME spot for competitive racing. Skip Allen recently retired from manufacturing the boats there and is enjoying life again on the pond... their club is quite active and you are in the perfect spot geographically for the "Dixie Cup" which is about a 7 regatta circuit that travels through NC (Raleigh, Elon last weekend) to GA (Lawrenceville) and coming up it goes to SC for (Blufton, Charleston, Columbia)
You would have several HUNDRED registered and raced boats within a few hours drive of your local club.
