About the Doughdish Sailboat

Designed by the legendary Nathanael Herreshoff, this compact 15.83-foot sailboat represents classic American small boat design at its finest. Built by Doughdish Inc. from 1972 onward, with 100 hulls constructed, the Doughdish embodies traditional sailing characteristics through its gaffhead sloop rig and long keel configuration with transom-hung rudder. The boat's substantial displacement of 1,500 pounds, nearly half of which is ballast, creates exceptional stability for its size. This weight distribution, combined with a comfort ratio of 16.39, makes the Doughdish remarkably seaworthy for coastal cruising and day sailing. The traditional long keel provides excellent directional stability and predictable handling characteristics that novice sailors will appreciate. With 140 square feet of sail area and a hull speed of 4.74 knots, the Doughdish prioritizes comfort and safety over speed. The capsize screening formula of 2.04 indicates good stability, while the wood and fiberglass construction offers both traditional aesthetics and practical durability. This design excels as a protected waters cruiser and sailing trainer, where its forgiving nature and Herreshoff pedigree shine. The gaff rig adds character while remaining manageable for single-handed sailing.
