The Excess 11 is a 37-foot catamaran built in fiberglass with a wide 21.6-foot beam. Powered by twin Yanmar diesel engines of 58 horsepower each, this 2025 model combines the design and construction standards of the Beneteau Group with practical cruising capability. The hull form and beam make her stable and spacious, suited to extended exploration of shallow anchorages and protected waters.
The Owner's Version layout includes five cabins: three full cabins for owners and guests, plus two crew cabins in the forepeaks. The owner's cabin features a 2-by-2-meter bed, and the two heads are each fitted with separate shower facilities. Public spaces focus on open, connected living—the large cockpit on deck includes twin helm stations, designed for sociability as well as steering control and sight lines.
Built as a new stock model, the catamaran is ready for immediate use. Equipment and systems reflect current production standards for the model.
