Montgomery 12
Description
The Montgomery 12 is an American sailing dinghy designed by Lyle Hess (the renowned naval architect behind many pocket cruisers like the Bristol Channel Cutter) as a daysailer and one-design racer, first built in 1972 by Montgomery Marine Products (founded by Jerry Montgomery in California). It was produced in fiberglass from the early 1970s into the 1980s, with several hundred hulls built (exact numbers not precisely documented but common in West Coast fleets). The boat features a centerboard dinghy hull for shallow draft and easy trailering/launching, a fractional sloop rig for responsive and forgiving handling, built-in flotation for unsinkability, and a simple, open cockpit ideal for club racing, family daysailing, or light exploring—praised for its nimble performance, stability in chop, and classic lines that make it a cult favorite among small-boat enthusiasts.
