Layout and Design

Built by Lyman-Morse Boatbuilding craftsmen with an uncompromising attention to detail,TUMBLEHOME represents Maine boatbuilding at its finest. The classic feel of the exterior, which uses teak to cover most horizontal surfaces and Awlgrip finishes on all vertical surfaces, is complimented by an interior that has been designed and selected specifically for function, quality and comfort.The upper level is paneled in cherry. The aft end of the salon showcases built-in furniture with a bookcase separating the dining area. A “pass-through” from the galley on to a side board makes it easy for the cook to service the dining guests.

The lower level contains two guest cabins, a master cabin, two crew staterooms and sitting/operation areas for the crew. The birch paneled master cabin uses the full beam of the boat to achieve a spacious functional area including king-sized bed, day bed and writing desk. The two guest cabins are identical with birch paneling, separate showers and entertainment centers.

The main helm station is spacious with an elevated sitting area for visibility and a comfortable helm chair.

The flybridge has a centerline helm with full instrumentation. All built-in flybridge furniture is constructed in fiberglass and Awlgrip finished.

This elegant 90′ vessel represents the best of boatbuilding design, craftsmanship and performance. No better statement can be made.

The 1997/2013, 90 ft. custom Motor yacht TUMBLEHOME was built by Lyman-Morse at their Thomaston, Maine shipyard . This luxury vessel’s sophisticated exterior design, styling and engineering are the work of C. Raymond Hunt Associates.A comfortable family cruiser, TUMBLEHOME has lots of “outdoor” spaces that include an inviting aft deck and top deck flybridge with spacious seating.  Cherry, teak, holly and red birch accentuate the interior. There is a spacious owner’s stateroom with a four-poster bed, roomy guest accommodations and ample crew’s quarters.

Having been repowered during her 2013 refit, motor yacht TUMBLEHOME is capable of a top speed of 27 knots, and comfortably cruises at 23 knots.

Designer Comments

The client who commissioned Tumblehome had previously owned a 60-ft Hunt-designed yacht. Her experience with that boat convinced her to move up to a larger Hunt design. At the time of construction, this was the largest FRP hull moulded by the SCRIMP resin infusion process, a technique which controls resin flow to produce a particularly strong and lightweight laminate. A comfortable family cruiser, Tumblehome has lots of “outdoor” spaces, including an aft deck the owner intended for her games of gin rummy. Cherry, teak, holly and red birch make up the interior spaces and recall the Maine roots of the owner. Roomy guest accommodations and a spacious owner’s stateroom with a four-poster bed (which holds up the deck) and ample crew’s quarters are below decks. Though conventional in many ways, Tumblehome was designed to have a distinctive teak sheathed deckhouse, but this detail was never completed owing to the owner’s untimely death during construction.
