Compact, Capable, and Rewarding

The SW 1170 is a 39-foot Category A cruiser built for couples who prioritize a lively, responsive sailing experience in a manageable package. Designed for those who want a vessel that is easy to handle without a full crew, it brings the legendary Seawind DNA into a size that fits comfortably in local marinas while remaining fully capable of blue-water crossings. This model is the favorite for sailors who appreciate tactile feedback and want a boat that feels balanced and playful, whether on a weekend getaway or a long-distance adventure.

Intuitive Deck Layout for Short-Handed Sailors

The deck layout of the Seawind 1170 is centered around safety and effortless sail handling, with all lines led aft to the protected twin helm stations. By utilizing stub keels and a self-tacking jib, the 1170 offers an offshore-ready simplicity that is rare in performance-oriented catamarans. The carbon-reinforced foam core construction provides a stiff, lightweight hull that feels balanced and playful even in lighter winds. This is a sailor’s boat, designed to provide tactile feedback through the cable-driven steering while keeping the crew secure behind the coachroof in more challenging conditions.

Space Management for the Independent Adventurer

The SW 1170 maximizes its footprint with a highly functional interior layout that prioritizes open-plan living and natural ventilation for the off-grid cruiser. By placing the galley in the hull, the saloon becomes a dedicated social hub with 360-degree panoramic views, essential for both situational awareness and relaxing at anchor. High-quality timber finishes and durable materials ensure the boat stands up to the maritime environment over the long term. With its generous fuel and water capacities, the 1170 is fully equipped for independent living, proving that a compact vessel can still offer the comfort and autonomy of a much larger yacht.

Not only do twin helm stations offer excellent weather protection and safety, they also give you direct line of sight visibility on all four corners of the boat from either helm.

Absolute Comfort Living Space

The Seawind 1170 has fantastic natural ventilation due to the large front opening Saloon windows, removable helm windows and trifold cockpit doorway. With the door secured safely into the cockpit roof when open, unrivalled open space is available for entertaining guests, unrestricted views and general living. With 6'5" headroom throughout, the 1170 has generous accommodation space for a 39 ft catamaran

Built Tough For Offshore Sailing

The Seawind 1170 bucks the trend of ever-larger boats. At 39 feet, this Category A cruiser is specifically engineered for serious offshore work, providing the ideal platform for a couple or small family to embark on a global adventure. Built with safety as the primary concern, the structure features carbon-reinforced foam core throughout, resulting in a stiff, immensely strong construction. This commitment to a practical and durable build, paired with deck layouts optimized for short-handed sailing, ensures the 1170 is more than capable of taking you wherever you want to go.

Uncomplicated and Refined Interiors

The Seawind 1170 uses a mix of structural composite furniture and timber finishes to keep the boat both light weight and functional whilst also having a high level of hand crafted timber fitout.

Owner's voice

1170 Experience

“The Seawind 1170 is the perfect, safe, and easy-to-handle boat for Nuscharee and me in our 70s. As a former pilot, I value its 'less is more' luxury. Key features like the increased freeboard, protected helms, and the tri-fold saloon/cockpit door system are simply fantastic.”
