AWARD-WINNING PERFORMANCE. UNMATCHED COMFORT. Winner of both SAIL’s Best Boat 2025 and Cruising World’s Boat of the Year 2025, the Seawind 1370 represents a true generational step forward in catamaran design. Built with a versatile and thoughtful design, tailored for long-term cruising, the spacious and functional layout of the 1370 caters to adventurous sailors and families alike, making it the ideal companion for both exhilarating voyages and comfortable living on the water. These features have earned the 1370 numerous prestigious awards and won the hearts of dedicated sailors worldwide, who...

DESIGNED FROM REAL OFFSHORE EXPERIENCE

The Seawind 1370 is the result of decades of offshore sailing experience, owner feedback, and practical boatbuilding knowledge. With a lightship displacement of approximately 11,000 kg, every design decision is shaped by how sailors actually use their boats at sea. Input from experienced owners and naval architects has been combined with extensive CFD analysis to refine hull performance. This ensures the boat maintains an optimal bridge deck clearance of 850mm, significantly reducing slamming in offshore conditions and improving overall crew comfort during long passages.

HULL DESIGN & ENGINEERING PHILOSOPHY The Seawind 1370 represents a generational leap in multihull design, combining thousands of man-hours in Computational Fluid Dynamics with owner feedback. Its engineering philosophy prioritizes a robust build using vacuum-infused vinylester resins and carbon-fiber reinforcement in high-load areas to achieve a high strength-toweight ratio. The hull features wave-piercing reverse bows and hard chines, which significantly reduce pitching and improve buoyancy in heavy seas. These design benefits ensure a smoother, drier ride and allow the vessel to maintain high...

PERFORMANCE YOU CAN TRUST OFFSHORE Performance on the Seawind 1370 is designed to be usable, predictable, and confidence-inspiring offshore. The standard upwind sail area of 116 square meters is supported by a high-aspect fractional rig that delivers consistent power. Balanced sail plans, refined hull shapes, and efficient weight distribution allow the boat to maintain speed without demanding constant attention from the crew. Whether sailing shorthanded or fully loaded for passage-making, the 1370 delivers consistent, manageable performance in a wide range of conditions.

TWIN HELMS & PROTECTED SAILING POSITION The Seawind 1370 refines the fleet's signature dual-helm configuration by prioritizing ergonomic control and technical accessibility. Each station is strategically positioned to provide an unobstructed 360-degree view of the horizon and sail trim while remaining sheltered from the elements. By centralizing all sail-handling lines and electric winches within reach of the helmsman, the design ensures that reefing and manoeuvring remain manageable tasks for a solo sailor or a small crew. This integrated command center allows the skipper to maintain high-performance...

SINGLE-LEVEL LIVING CONCEPT The architectural core of the 1370 is its flush-deck transition, which eliminates traditional physical barriers between the saloon, galley, and cockpit. This engineering choice focuses on safety and mobility, significantly reducing the fatigue and risk associated with navigating stairs while underway in heavy seas. By maintaining a consistent floor height across the primary living and working zones, the layout facilitates effortless movement and clear sightlines for the crew. Beyond its functional benefits, this design transforms the boat into a vast, cohesive pavilion...

While performance is a hallmark of the 1370, this vessel is specifically optimized for the unique demands of permanent residency on the water. The design emphasizes climate control and environmental connection through the use of signature tri-fold doors and forward-opening windows that create a natural cross-flow breeze, reducing the reliance on air conditioning. Storage solutions and interior volume are scaled for high-capacity provisioning, ensuring that the boat remains practical and uncluttered during months-long voyages. Every aspect of the living space is crafted to provide the comforts...

INTERIOR VOLUME, STORAGE & LIVEABOARD COMFORT Headroom and interior volume are carefully balanced to support comfort without compromising offshore performance. Storage is integrated throughout the boat, both inside and out, allowing equipment, provisions, and personal items to be stowed securely and kept dry. This reduces clutter and improves safety at sea.

GALLEY & ONBOARD PRACTICALITY The galley is fully equipped for extended cruising, with ample refrigeration, storage, and workspace. An integrated cockpit BBQ and sink support outdoor living, while multiple lounging areas in the cockpit and foredeck provide flexibility for different conditions and social settings. Every system and layout choice is guided by practicality, durability, and ease of use offshore.
