Malihini

035

Malihini is a catamaran we almost bought in partnership. That deal didn’t work out, but I’ll leave the page up for any curious sailors that might stop by.

DESIGN
John Shuttleworth designed catamaran with round bilges, plumb bows and dagger board in each hull. Flush decks and open cockpit aft; companionway with hatches steps down to cabin areas in each hull.


Video of Shuttle 31 Atlantic Crossing
Students at a high school in Switzerland built two Shuttle 31s. 4 feet shorter than Malihini. Two other groups of students from the same school sailed them across the Atlantic and back. The video they made is in German with English subtitles. Well worth the watch.

CONSTRUCTION
Constructed by Doug and Sharon Gibson of Kauai. They primarily sailed Malihini in Hawaiian waters, out of Nawiliwili Harbor, but they also sailed her to Los Angeles and back.

She is all foam core/epoxy/vacuum bagged construction.
Hulls are a composite of 20 oz. uni-E-glass, 5/8 thick, 8 lb. Divinicell foam; 24 oz. uni-B-glass, all epoxy resin and vacuum bagged.
Bulkheads are 1/2″ Divinicell foam with 15 oz. uni-“E” glass and epoxy resin; 4″ tabbings
Decking is E-glass/epoxy; foam core; vacuum bagged; Awlgrip LP paint and non-skid
Composite chain-plates, carbon rudders/post, dagger-boards, main beams
Each hull has (6) watertight compartments in the bilges. The rudders, rudder posts, dagger boards, tillers are all foam with carbon cloth and epoxy resin.
Rudder is FG/foam epoxy twin-balanced spade kick-up and steering in tiller across cockpit connected with tiller bar
Finished in Awlgrip
