Hi Franz,
There is fleet 448 located in Rhode Island which does 8-10 events during the season, mostly fun sails but I'd like to think with more interest, we can get more racing going. There is also fleet 207 in Maine who is going to host a regatta at Lake Sebago this sept. Check the fleet 448 website for events
www.fleet448.org. For really competitive racing you would have to drive down south to NJ or upstate New York ( fleet 204 ). Let me know where you are exactly and I can point you in the direction to point you in for beach launching areas.
Welcome to the area!
Blair
