2018 Eastern 31 Casco Bay

location icon Hingham, Massachusetts
Year 2018
Length 31 ft

This Eastern 310 Casco Bay is set to show off a custom interior layout, comfortable helm and double mate seating, generator, air conditioning, and a number of additional items, meant to provide you with comfort, handling, and performance.

Eastern’s 310 Casco Bay runs on a Downeast thoroughbred 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 310 has hard chines, giving her excellent speed, efficiency, and stability both underway and at rest.  With a 330-400-hp modern diesel, she will cruise comfortably at 16-18 knots even in rough seas.  Over 450 of these 31′ hulls are running on all three coasts and the Great Lakes today.  We can finish one for you as a basic work boat, 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.  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 310 for you?

All of the boats start with 3 ounces of mat wet out in vinylester resin (not just sprayed on) over the gelcoat to help prevent osmotic blistering and improve the cosmetic finish by reducing print-through.  All of the hulls are supported by female-molded fiberglass grids, which produce a consistent hull support structure and foundation for the deck and fuel tanks while providing a tooled bilge back aft. The grids are also designed to double as rigging tubes, which allow wires and hoses to be routed. Once they are bonded in place, the grids are filled with foam to add flotation, stiffen the grid structure and quiet the ride. The Eastern 31 and 35 hulls, decks and bulkheads are cored with Nida-Core, a high-end plastic honeycomb structural core that also does a great job of reducing noise in the hull bottom and sides. Two layers of 1808 (a non-woven fiberglass reinforcement) go on inside and outside of the core. The hull is solid glass at the sheer, chines and keel to accept fasteners and resist compression. All of the boats get Nida-Core cored bulkheads and decks, and it’s this use of relatively high-tech materials that makes the boats so much lighter than they would be with solid fiberglass or plywood cored structures.

Cabin Layout

One of the truly remarkable features of the Eastern 31 is the ability to have the boat built to suit your needs and intended use. The factory takes great pride in its ability to provide semi-custom versatility at a very reasonable price. These are not cookie-cutter boats that "must" be built a certain way, because that is how the tooling is built.  The 31 can be arranged for Lobstering, Fishing, Cruising, or a combination of uses.
