Walter Greene is an American naval architect and boatbuilder based in Yarmouth (Maine), specializing in oceanic multihulls. He co-designed withDick Newick the Acapella series of trimaransAcapella (12 m / 39'4"), whose first unit — renamedOlympus Photo — won the first Route du Rhum in 1978 with Mike Birch, beating the monohullKriter V by 98 seconds after 23 days of racing.
The Greene Marine yard
Walter Greene founded Greene Marine in 1980 in Yarmouth (Maine), on the Cousins River, with his wife Joan and his sister Esther. The yard works with wood, epoxy, fiberglass, and then carbon fiber. Over nearly forty years, Greene built or contributed to more than 150 boats, mostly racing and cruising multihulls.
The Acapella series
Five Acapella trimarans were built at the yard starting in 1978. Lightweight construction, 12 m platform, 16.8 m mast, 2.5-tonne displacement — the architecture co-signed with Dick Newick shifted ocean racing toward multihulls. Walter and Joan Greene themselves raced an Acapella in the 1978 Round Britain, finishing 1st in class and 4th overall.
