Join the Family

Membership in the largest one-design catamaran class in the world provides many benefits, both tangible and intangible. In addition to supporting noble causes, like the Guest Expert and Youth programs, a healthy class association helps maintain the resale value of your boat!

The IHCA Class Rules require at least one crewperson on each boat be a class member to participate in class-sanctioned events (Points Regattas). Membership is also required to be included in the North American Competitor Ranking System. At the North American Championships, all crewpersons on each boat are required to be class members. Fortunately, there are several levels of membership, most of which cost less than a night at the movies!
