Depends on how serious you guys are at your club, and who is racing. At our beach, when all the F18's are on the water, it tends to be more serious (but not very... more about yuks than anything else) than when its a Heinz 57 start with every imaginibale one of a kind out there. Heck, we raced last weekend and were the only F18 out there, and the RO gave an order to one of the mono hulls to shorten the course, right as we were on approach to round it for the second time. We chased down, and rounded the moving mark on port tack laughing all the way!
