2025 Excess 11

The Excess 11 is a 37-foot fiberglass catamaran built for extended cruising in remote waters. Twin 60-horsepower Yanmar diesel engines provide propulsion, while a 10.5 kVA genset supports onboard systems. The hull's wide 21.5-foot beam creates substantial interior volume and deck space, with twin helm stations offering direct steering control and a spacious open cockpit for crew comfort.

Below deck, the boat sleeps four with two heads and separate showers. The owner's cabin features a 2 by 2-meter bed, and cabin and saloon spaces are generously proportioned. Air conditioning serves all cabins and the saloon. A watermaker enables extended periods away from shore infrastructure.

On deck, the design prioritizes accessibility and safety with protected walkways and a logic-forward layout. The catamaran is fitted out as a high-specification cruising platform, combining the comfort and space of a larger vessel with the efficiency and maneuverability expected of a 37-footer.
