If you don't want to sail in class regattas and it makes the old Fairwind tub go faster I'm with you all the way. We have about eight Fairwinds on our pond but the club is very informal. We have four rules. #1 is no formal meetings, just come to the pond on Thursday mornings. #2 is NO OFFICERS. #3 is no dues of any kind. #4 is no racing.
I put all the "go fasts" that the class allows on my boat and it didn't go enough faster to make the extra work worth the trouble. Sold it to a guy in another state who races. He's happy and I have the money to build a third Soling 1M which I like. Not really fast but a good boat in a breeze.
Keep on having fun !
