One Design Principles

Since it's founding, the International Class has remained committed to the tradition of testing sailing skills in equally equipped yachts. The Class' extensive one-design rules endeavor to ensure that the hulls, rigs and sails of the racing yachts are near equal as possible. All International owners agree to honor this Class principle. To keep costs low and ensure the most equal sails possible, the fleet votes each year on what sail, if any, will be purchased. (Typically, mainsails are sailed for six seasons, and jibs and spinnakers are sailed for three seasons each before replacement) The sails are ordered in a single lot from the local fleet's official sailmaker, who pledges to make them as near equal as possible. No recutting, or use of alternate sails is permitted.

To further equalize the playing field during International and Interfleet regattas, a change-boat series is presented by the host fleet. Competitors do not bring their own boats to such an event, rather they are invited to sail in the boats of the host fleet. The local representative is prohibited, by rule, from sailing their own boat. Boats are rotated after every race, or at some events, each day.
