The Stuart Knockabout is an American trailerable sailboat that was designed as a daysailer, by L. Francis Herreshoff and first built in 1932. The boat is L.F. Herreshoff design number 53.
The boat was a commission for a single boat to be designed and built for Willoughby Stuart in 1932. Stuart was seeking a large daysailer with a shallow draft that had ease of handling, capacity and comfort. The boat only entered production in 1989, some 17 years after the designer's death.
