what an interesting idea....make a BIG triangle course (2 to 3 miles) and make everyone sail X number of laps (more for the big boats) - like an automobile race! Man, that would be fun! A Big long reaching leg right in front of the spectators too! Have two or three races in a weekend so you have a chance to catch up. Now to think of a name....
Take your biggest sponsor and honor them by calling it the "West Marine 10 miler" or something. Or perhaps each race (three in a weekend) could be named after each sponser.
