SEAWIND 1370
Winner of both SAIL’s Best Boat 2025 and Cruising World’s Boat of the Year 2025, the Seawind 1370 represents a generational leap forward in catamaran design. Light and nimble through meticulous design and advanced lightweight construction, it handles heavy loads with minimal impact on performance. Built for a perfect balance of bluewater performance and liveaboard comfort, this award-winning catamaran is the ultimate choice for modern sailors seeking adventure without compromise.
FAST & EFFICIENT HULL DESIGN
THE PERFECT BALANCE OF PERFORMANCE & SAFETY
Key to the brief with our design partners, The Yacht Design Collective, the 1370 strikes a balance between performance and safe, comfortable sea keeping. The weight of the vessel sits in the top of category, just under the category that requires significant additional cost in full carbon epoxy construction, making making the 1370 light and nimble for a significantly spacious 45-footer. Crucially the 1370 is capable of being heavily loaded with only the minimum of impact on sailing performance. Countless hours have been invested in Computational Fluid Dynamic (CFD) studies in order to discover the best balance of speed, and comfort under sail enabling Seawind to favor robust systems such as mini keels and spade rudders whilst not sacrificing on cruising performance.
SAFE & PROTECTED HELMS
THE PERFECT BALANCE OF PERFORMANCE & LIFESTYLE
This single-level cruising catamaran boasts Seawind Catamarans’ indispensable twin protected helms which offer skippers complete protection and 360 degree visibility. Sheets, reefs and halyards are all led aft to electric sheet winches at the helms making rough, offshore passages more comfortable and achievable from the safety of the dry and protected cockpit.
BLUEWATER CRUISING IN UNRIVALLED COMFORT
THE PERFECT BALANCE OF PERFORMANCE & LIFESTYLE
Open-plan living, with saloon, galley, cockpit and helms all on one level, this catamaran boasts incomparable open living area. But not content with ticking all of the boxes, the 1370 catamaran model advances one step further with another Seawind first – the innovative new breakfast (or evening) bar with integrated seating. It will make taking that first rest after a day of fast sailing a truly simple pleasure and serve as a coffee area in the morning when you’re ready to get going. The 1370 includes an integrated cockpit BBQ and sink, as well as foredeck and cockpit lounges.
DESIGNED FOR SHORTHANDED COUPLES
THE PERFECT BALANCE OF PERFORMANCE & ERGONOMICS
Seawind Catamarans deployed countless thousands of man-hours in hull design and optimization, in this design collaboration with The Yacht Design Collective, and spared no expense in refining the crucial sailing ergonomics suited to a modern cruising couple. The new 1370 catamaran model has the high aim of striking the perfect balance between performance and comfort in a 45’ bluewater cruiser – this catamaran is designed to be the best go-anywhere, live-aboard cruising sailboat available today. Our rigorous design efforts have produced a hull capable of truly thrilling light air and heavy weather speeds and impressive pointing ability while being easy to handle shorthanded or single-handed.
BLUEWATER CRUISING IN UNRIVALLED COMFORT
THE BEST OF BOTH WORLDS HIGH SPECIFICATION WITH CRAFTSMANSHIP
This all-new catamaran is equipped with all of the modern necessities, while employing true boatbuilding craftsmanship at every level. The 1370 catamaran model is fitted with exquisitely crafted carpentry throughout, complimented by a well balanced saloon that is bathed in bright natural light and ventilating airflow thanks to Seawinds famed tri-fold door and essential fwd opening window system. The comprehensively equipped galley comes standard with bar fridge, large 130l chest freezer, and an abundance of storage, making it ideal for extended cruising and responding to sailing couples with varying needs for toys and equipment on their own unique voyage.

THE BLUEWATER CATAMARAN FOR ADVENTUROUS SAILORS
Adopting all of the best advances made in the last decade of catamaran designs, and incorporating countless innovations in hull dynamics, structural engineering, exotic composite materials and manufacturing methods, where other Seawind Catamarans have been built tough - the 1370 will be bulletproof.
We have taken the feedback of hundreds of existing catamaran owners and sailors, and combined them with the practical experience and build principles of our senior shipwrights, to create a sailboat design and structure that perfectly merged these two perspectives.
The impressive reverse bows on the Seawind 1370 aren’t just a show piece. They are central to this catamaran design, by way of targeting the wave-piercing aspect to their effectiveness in reduce pitching, this hull design provides enhanced sailing comfort and safety through a smoother and more stable ride.
Seawind 1370 ticks all of our boxes
A performance-oriented, safe, bluewater-capable catamaran that is large enough to carry a payload for extended cruising but manageable by two people... The Seawind 1370 ticks all those boxes..." - Sailing Yacht Ruby Rose on the announcement of the new Seawind 1370
