Length and beam rules are as stated in the announcement. Because the wind often blows straight on to the beach in Texas at that time of year, it would be difficult to safely manage larger catamarans in the surf. Therefore, we imposed the 10 foot beam limit. In addition, we wanted approximately the same speed boats, thus, we chose 18-22 foot boats. No boat restrictions are ever perfect, however, based upon our experience in sailing in the surf, in Texas, and in long distance races, we felt these were appropriate limits for this race. I thank you for your interest in this subject.
