31' Casco Bay

     Eastern’s 31' Casco Bay runs on another thoroughbred Downeast hull from famed designer Royal Lowell.  Her graceful sheer, flared bow, clipper stem, and full keel have given her legendary seaworthiness.  Unlike most of Lowell’s hulls, though, our 31' has hard chines, giving her excellent speed, efficiency, and stability both underway and at rest.  With a modern 370-400-hp diesel, she will cruise comfortably at 16-18 knots even in rough seas, while her classic flare and forward spray rail keep her windshield dry.


     Over 450 of these 31′ hulls are running on all three coasts and the Great Lakes today.  Some are fishing commercially, many are carrying fishing charters or hard-core recreational anglers, and more are cruising with their families.  We can finish one for you as a basic workboat, a Coast-Guard-certified passenger vessel, a state of-the-art sportfisherman, or a lobster yacht with all the teak trim. Our standard Casco Bay model adapts well to any of these uses, with or without a flying bridge.  Accommodations below include a roomy forward V-berth, an enclosed head with shower, and a hanging locker.

      Her pilothouse offers comfortable helm and companion seats, a settee/dinette that converts to a double bunk, and a galley with two-burner stove, countertop, sink, and refrigerator.  Her roomy cockpit can host picnics or adapt for fishing action.  Options include heating/air conditioning, a 3.5 kW genset, a molded transom platform, and a transom door, but we have broad experience with custom installation of other equipment requested by owners. How can we fit out an Eastern 31 for you?
