2025 Excess 11

The Excess 11 is a 37-foot fiberglass catamaran built for serious cruising. Its wide 21.6-foot beam delivers the interior volume and stability that larger monohulls cannot match at this size, making it one of the few production catamarans in its class designed for extended offshore passage-making.

The layout includes three cabins and two heads, offering comfortable accommodation for cruising families or small groups. The catamaran's design balances livable space with the sailing performance expected from a modern cruising boat.

Power comes from twin Yanmar diesel engines rated at 60 horsepower each, providing dependable propulsion for auxiliary use and maneuvering. The fiberglass hull construction ensures durability and low maintenance for long-term cruising.
