The 2023 Excess 11 is a 37-foot fiberglass catamaran built to 2024 specifications. It is powered by two Yanmar 3YM30AE diesel engines of 30 hp each, with 500 hours of operation logged. The hull features twin keels for stability and maneuverability in varied conditions.
The interior accommodates five cabins and two heads, providing comfortable spaces for extended cruising or family use. The layout balances living areas with sleeping quarters, suited to both longer passages and periodic getaways.
The boat was recently antifouled and relaunched in June 2026, indicating active maintenance and seasonal readiness. It is built on a fiberglass hull with the design refinements of the current Excess lineup.
