This 1992 Duffy 31 is a classic Downeast lobster boat built by Duffy & Duffy Boatbuilders in Brooklin, Maine. The 31-foot hull, constructed from fiberglass, carries the 11-foot beam typical of the design—a form proven for strength and seaworthiness in coastal conditions. The boat is powered by a Cummins engine, offering the reliability and simplicity that defines this style.
The Duffy 31 was designed for serious work in rough waters, with straightforward systems and rugged construction that support both commercial lobstering and recreational cruising. The traditional Downeast layout prioritizes function and durability, making it a practical platform for extended time at sea.
