Designed by Sparkman & Stephens in 1946, the InterClub, or "Ick", is a sturdily built, relatively dry 11.5 foot dinghy created for winter sailing or "frostbiting" as it is commonly known. Sailing legend Cornelius Shields introduced the one-design at Larchmont Yacht Club, Long Island.
Soon frostbite fleets sprang up in coves and harbors between Boston, Massachusetts and Annapolis, Maryland. Each IC fleet operates autonomously. However, when fleets come together for yearly Midwinters and National regattas, IC technical regulations are strictly enforced. Frostbite courses are short, with multiple races per day. This sharpens boat handling and tactical skills, giving these "off season" sailors an edge when summer regattas begin.
