The Seawind 1170 is a 39-foot bluewater cruising catamaran built from composite construction with PVC foam sandwich and carbon reinforcement. Twin Yanmar diesel engines of 58 horsepower combined power the hull, with fuel capacity of 500 liters and water capacity of 600 liters supporting extended offshore passages. The boat holds CE Category A offshore certification and was recognized as Multihull Yacht of the Year 2025 at the British Yachting Awards.
The design prioritizes easy handling for couples or small crews. Twin protected helm stations and a high-aspect rig with self-tacking jib allow confident short-handed operation. The interior features Seawind's tri-fold door connecting the cockpit and saloon into a unified living space, with 6 feet 5 inches of headroom throughout. A three-cabin layout includes a dedicated owner's hull, with ventilation designed for tropical and long-passage cruising.
The accommodations blend practical cruising space with comfort. The open plan galley, saloon, and cockpit flow together via the folding door system, maximizing usable area on deck and below. Storage and systems are configured for self-sufficient voyaging, reflecting the boat's design intent as a true offshore platform scaled to remain manageable without crew or complex engineering.
