instead of racing around a triangle, why dont you have a scavanger/treasure hunt kind of competition? have organizers take participants and team them up. try to even the teams by taking boat construction, ability, ect into account. dont let anybody have the "treasure maps" until the start. do a shotgun start. it would be pretty cool having all of those boats going in different directions. have them go to different points and have to get out of the boat and "find" the whatever as proof as being there. there would be all kinds of strategey to contemplate. and this would make for an excellent ice breaker as far as sailors working together. at the end, have a bbq. hand out awards for those who do well in the scavanger hunt but also an equal amount of recognition awards. ie best pirate, oldie but goodie, best floating wreck, ect. everybody should get some kind of participation thing ie pin or t shirt. the main thing is to have fun and lots of it with fellow sailors.
