Sorry Jack.... when I crewed at the mini macho man (you raced against me and Catman) was about the extent of my willingness to travel to race (yes at my local beach).
But i am 100% behind you guys who live/love to race. I think one of my biggest hesitations is my lack of knowledge of the rules (that and because i am slow...

).
I did agree to race again at the Liberty Race (even skipper) because my 74 year old crew is holding me to my word.... he has promised to "learn me" some rules...
Not knowing the rules shouldn't keep you from racing Andrew. 99% of the race you are not close enough to anyone for it to matter. Especially where you race. If someone yells at you, so what. Use that as a learning experience.
If you are uncertain about your rights, just keep away from close encounters. The only place it gets close is at the strat. Just give everyone space until you know what you are doing. If you lag back a little, you may even be better off than some of the guys fighting for position.
You are not going to be racing in a race where it matters. JUST DO IT!
