1996 Brooklin Boat Yard 32' _{(9.75 m)} Center Harbor 31

Center Harbor 31, SENSHIN

SENSHIN is hull #2 of the highly acclaimed Center Harbor 31 class, designed by Joel White and built by Brooklin Boat Yard as fine daysailers and weekenders. An early example of the Spirit of Tradition genre, the class was inspired by L. Francis Herreshoff’s classic QUIET TUNE design, but designed to be much more user-friendly than her classic cousin, incorporating low-maintenance wood/epoxy composite construction, modern rig and underbody, and much-reduced displacement for sparkling performance, both on the race course and in casual daysailing.

The focal point of the design is an expansive cockpit, long enough to seat a crowd on nine-foot-long, ergonomically-shaped teak benches. Pocket accommodations invite weekending, with galley area, enclosed head and vee-berths below.

SENSHIN features a longer bow overhang than her sisters, for a more sweeping profile and an additional foot of overall length, making her 32 feet long. She also features an additional three inches of freeboard for more interior volume and a drier sailing experience. 

Lovingly maintained by her current owner over more than a decade, Senshin underwent an extensive refit in 2019. Optimized by Stephens Waring Design, with construction performed by Rockport Marine, the refit included a custom deeper, narrower fin keel with bulb and modern foil design as a significant upgrade from the original 1990’s fin keel, and a sleek new spade rudder with roller-bearings, as well as a refresh of deck hardware with addition of a Code Zero headsail to the inventory. She has seen considerable racing success under current ownership in both PHRF fleets and in classic regattas, partly due to her owner keeping her sail inventory up-to-date with modern sail technology.

Description:

Deck and Cockpit:

Deck is painted with Awlgrip, non-skid. Joinery is varnished Honduras mahogany, including toe rails, cockpit coamings and cabin trunk, companionway slide and drop-boards, primary winch plinths. Custom chrome-plated cast bronze chocks at bow and stern. Chainplates of custom-fabricated stainless steel.

Cockpit is self-bailing with painted non-skid Awlgrip. Engine hatch in forward end of cockpit sole. Four opening cockpit seat lockers offering capacious storage for sails and gear; aft starboard locker is insulated and drained to serve as ice chest. Painted footwell sides and cockpit sides below varnished coamings, with storage cubbies outboard of seats for winch-handles and other small gear. Cockpit seats are quarter-sawn solid teak, raked and carved to shape for comfortable seating. Curved laminated varnished mahogany tiller. Lazarette accessed through aft bulkhead of cockpit.

Accommodations:

The companionway is offset to starboard, providing airiness for galley area and extra room for enclosed head to port. The enclosed head uses a curved door for easier access and provides privacy for using the manual marine toilet. The galley offers stainless steel sink with fresh water via hand pump, counter space for prep or cooking using a single-burner free-standing butane stove, and cabinets for dish and dry-goods storage outboard.

Next forward, two upholstered seats face each other, carefully crafted for comfortable sitting, with storage outboard. Forward of the seats is a vee-berth. An open anchor/sail locker is forward of berths.

Construction:

The hull is built of wood/epoxy composite construction. Hull skin is ¾-inch strip planking of northern white cedar, epoxy-glued and fastened to laminated frames with bronze screws. The strip planking is sheathed on the outside with two layers 1/8-inch mahogany, laid in opposing diagonals and vacuum-bagged to strip planking. All is thoroughly epoxy-coated. Frames are laminated Douglas Fir. Floor timbers are 1-1/2 inch mahogany. Bulkheads and longitudinal panels are 12mm and 18mm mahogany marine plywood. Sheer clamps and deck beams are laminated clear northern spruce, varnished. Deck is 12mm (12-inch) marine plywood, sheathed on top with Dynel and painted with Awlgrip. Keelson is laminated Honduras mahogany. Cabin sides are 1-inch Honduras mahogany, varnished inside and out. Cabin top is laminated of three layers of 6mm mahogany marine plywood, obviating the need for beams.

When the new keel was installed, the floor grid system was redesigned and reinforced to incorporate longitudinal structure of mahogany with a top plate grid of ¼-inch thick G-10 fiberglass plate to assure that grounding loads would be well-distributed into the hull structure and bulkheads.
