What rules are they not using? Our area''s PHRF committee has some safety requirements that vary according to where the race takes place -- open ocean or protected sound. Not much else, rule-wise, from them. I have heard that some areas have weight/crew number limits, too. Class rules are determined by each individual class association - not by PHRF committees. PHRF and USSA generally OK whatever the class allows, within the bounds of safety, as above. What kind of rules are we talking about?
