Used Interlake Sailboats for Sale

The Interlake sailboat, an 18-foot fractional sloop, was originally commissioned by the Sandusky Sailing Club in 1933. Designed by Francis Sweisguth, renowned for his work on the Star class, the Interlake was specifically created to navigate the distinct waters of Lake Erie and Sandusky Bay. It quickly gained a reputation as a fast, maneuverable one-design racer, designed for two to three crew members, and capable of both competitive sailing and family day-sailing. Over the years, Customflex, a builder with a strong legacy in one-design racing dinghies, became notably involved in the production of Interlake class boats, contributing to the class's enduring popularity.
