Interlake (dinghy)

The Interlake is a 19-foot, one-design sailboat class recognized by US Sailing. Designed by Francis Sweisguth in 1932, it is a popular choice for recreational sailing and racing, particularly in inland lakes and protected coastal waters. The Interlake is known for its stable hull, good handling characteristics, and active class association.

The boat features a hard-chine hull, meaning the hull has a distinct angle between the side and bottom. It typically carries a crew of two to four people. The Interlake class rules emphasize strict one-design specifications to ensure fair competition. These rules cover aspects of the boat's construction, including hull shape, weight, and sail dimensions.

The Interlake's construction has evolved over time, originally built of wood and later transitioning to fiberglass. Modern Interlakes are typically constructed of fiberglass. Regardless of the material, the one-design rules maintain a consistent platform for racing.

The Interlake Class Association provides support to sailors, organizes regattas, and enforces the class rules. Many local fleets exist throughout the United States, offering opportunities for both casual sailing and competitive racing. The class promotes a welcoming atmosphere and encourages participation from sailors of all skill levels.
