The INTERNATIONAL SUNFISH® CLASS ASSOCIATION (ISCA) was formed to bring together sailors with an interest in Sunfish sailing. In 1984, the Sunfish Class was recognized by the International Yacht Racing Union and granted International Status. Under the new organization, Class members enjoy all the privileges of being an International Sailboat Class, including consideration for Pan-Am and Olympic status. ISCA ensures equal opportunity for all sailors preserving the Sunfish as a true one-design sailboat. Activities are organized for all sailors at the local and international levels. ISCA members enjoy all these benefits and more. The United States Sunfish Class Association (USSCA) is the ISCA-recognized authority within the USA. By joining USSCA, members are automatically members of ISCA.
All USA Sunfish owners are urged to become members of USSCA. Upon receipt of the registration form and fee, USSCA will assign an official sail number. A sailor who buys a new boat may retain their original sail number if the old sail is not sold with the number on it. Replacement or newly assigned numbers are to be in accordance with ISCA Class Rules. Note that as of January 1, 2015, any new or replacement numbers shall be a minimum of 300mm or 11 13/16”, easy to read, and either rounded in shape or digital "8" style. These styles of numbers may be purchased through most marine suppliers. If further information is needed, contact the class office for assistance.
For USSCA, a Family membership is available to sailors living at the same address and provides an ISCA membership card for each member. Youth membership is available at a discount. A Youth is defined as an individual who is not 19 years old or older during the calendar year. USSCA membership entitles sailors to race in sanctioned events at the regional, national and international levels. Members are also given a voice in the organization, including voting privileges at the Annual Class Meeting held each year at the North American Championship site.
