The Oyster 655 is a luxury bluewater cruising sloop built by Oyster Marine of the United Kingdom, produced from approximately 2006 to 2011 before being succeeded by the Oyster 625. Designed by Rob Humphreys, the 655 represents the pinnacle of Oyster''s volume production — a 68-foot flagship intended for extended offshore voyaging by experienced owners with professional crew or serious passage-making couples. The hull features a high-performance bulb keel that delivers exceptional stiffness and allows the boat to carry full sail longer than comparable designs, while the interior is fitted out to a superyacht standard with teak and holly sole, custom joinery, and multiple owner stateroom configurations. At over 85,000 pounds displacement, the 655 offers a comfort ratio over 43 and a sub-1.7 capsize ratio, making her one of the most sea-kindly production yachts of her era.
