Why don't you borrow an A Cat and go and sail it at a regatta, you will almost certainly end up with a bunch of people who enjoy the same sport you do, get to sail a fabulous boat and hopefully go home realising that it does not really matter which cat class you sail in, its all good fun and its your choice. I am guessing you built your own F16 so that you could "improve" a few things on it. All new cars still have 4 wheels and an engine, but they are getting better. Be nice!
