55 Eastbay SX
About the 55 Eastbay SX
Our passion for building the best-performing, most enduring and alluring boats has reached new heights with the 55SX: New heights of luxury in a restyled, dual-stateroom layout with large master and equally spacious VIP cabin. New heights of style, from her powered sunroof down to a granite-topped galley. Of comfort, with more seating, a large bar and entertainment center, and a separate raised dinette. And power, with engine options up to twin 1,015 hp diesels and top speeds over 30 knots.

Built on the acclaimed Eastbay Series hull designed by C.R. Hunt Associates, the 55 Eastbay is available as an enclosed-salon 'SX' model and now as as a flybridge-topped 'FB' model.
