Interior Accommodations 

Beginning forward is the guest cabin with en-suite head. The V-berth style bunk is 6’2” long with 6’1” of standing headroom. The hull sides are lined with wood battens creating a warm atmosphere. The overhead is paneling covered in white vinyl and held in place with teak battens. Daylight easily finds its way in through the large overhead hatch and two opening portlights on either side of the hull. Soft lighting is available through indirect LED strip lights hidden behind shelves along the hull. Storage is plentiful in this space; six small drawers, two larger drawers below the bunk, and a cedar lined hanging locker. The en-suite head is just aft and to starboard. The space is quite generous for a guest head and features a Raritan manual flush toilet, navy blue Corian countertops, two storage lockers and 6’ of standing headroom.  

Situated centrally is the main salon. Here, there is 6’5” of headroom and enough seating for a dinner party. The port side has a linear 6’ 3” settee with book storage, built-in cocktail bar, and media storage at the forward end. A Dickinson Antarctic heater warms the cabin effectively and offers a cozy atmosphere on chilly days. The starboard side of the salon has an L-shaped settee and a large, custom fixed table with storage below. The settee has storage outboard along the hull and above there is a large cabinet for storage. The main salon is bright, spacious and accommodating for dinner parties or large scale projects while cruising.  

The U-shaped galley is part of the main salon just aft on the port side with Corian countertops throughout. The large stainless single basin sink is to the left when entering the galley with storage below and concealed access to the engine. There is a large stainless drainboard for a dish rack to the right of the sink. The adjoining countertop at the bottom of the ‘U’ is ideal for food and plate prep with three drawers for cooking utensils and one cabinet for dinnerware, making for ease in meal preparation. On the outboard side of the galley is countertop access to the refrigerator, a three-burner stove with oven, and another spacious countertop with a trash compactor below. Above and along the hull are three cabinets that hinge down for extra counter surface, and are excellent for food and spice storage as well as for other frequently used items. A microwave oven is built into the bulkhead over the countertop at the aft end of the galley space.  

The companionway separates the galley from the navigation station and conceals the engine. The entrance into the main salon has five steps and its design keeps the main salon feeling spacious when entertaining a large group down below. The navigation station is on the starboard side opposite the galley. It features a large flip up chart table, and a swing out seat with front and center access to the electronics. Three drawers are to the right including a filing cabinet for important ships papers, tools or quick grab items. Along that face and farther aft is a top loading freezer compartment and a hanging locker or pantry. The main AC/DC electronics panel is opposite the nav station.  

Through the passageway and aft is the master cabin and en-suite head. This large aft stateroom has a walkaround queen berth with custom Tempurpedic mattress, tons of light, and a generous amount of storage. A large hanging locker is immediately to the left when entering the cabin and three drawers for storage with a small countertop follow next aft. Two drawers are below the bunk and on the port side of the cabin there is another countertop with a mirror above and three drawers below. There is also a Dickenson Newport propane heater for cold nights.  

The en-suite head is accessed through a cherry trimmed doorway on the port side of the cabin. There is a manual flush, Raritan toilet separated from the shower stall by a half bulkhead and the sink is almost on centerline. The shower stall has a teak grate and built in seat outboard with a brass towel bar and hand hold along the forward bulkhead of the compartment. There is a handheld shower nozzle with a single faucet for temperature adjustment. There is storage outboard, a singular opening portlight and two light fixtures overhead.

Deck and Hull 

The topsides of Thumper III are a white gelcoat that has been recently cut and waxed. There is a dark blue boot stripe at the waterline with black Seahawk Sharkskin bottom paint applied in February of 2023. A rub rail runs the length of the topsides which is visually pleasing to the eye because of the large freeboard. A freshly varnished teak toe rail makes the transition from hull to deck well and adds function when sailing. The decks have molded-in non-skid, and the cabin top is white gel coat. A varnished teak eyebrow trim accents the cabin house just above the house windows.  

Both the hull and deck are laid with a fiberglass skin and Balsa core. Vinylester barrier resin was used in construction and Tillotson-Pearson took care in the build process to eliminate any voids. Balsa core lends excellent thermal and acoustic insulation properties. Taking care to properly install deck fittings and additional fasteners is imperative. The hull and deck are fastened together by stainless fasteners and permanent adhesive caulk, or 3M-5200.
