It’s here! Check out Billy and Sierra’s new Seawind 1170.

The Seawind 1170 – The new standard in 40 foot class catamaran design.

If you are looking for a 40 foot class catamaran with the modern lines and amenities of the Seawind 1370, but in a size that’s ideal for a cruising couple who don’t want or need to bring all the world’s excess baggage with them, then the Seawind 1170 is for you.

This all new 39 foot CE Category A catamaran was designed with performance in mind, without sacrificing any of the features Seawind is so famous for, including twin protected helms, Seawind’s signature trifold doors and large forward opening saloon windows. Carbon has been extensively used to reinforce the structure in high load areas, while the hulls are fully infused with vinylester resin.

Like all Seawinds, the Seawind 1170 is equipped to take you further, faster, safer. Twin Yanmar 29hp diesels, combined with 132 gallons of diesel storage, 160 gallons of water storage and ample space for large solar and lithium installations means the 1170 is well suited to those looking for a boat that is optimized for full live aboard, blue water sailing.

The new Seawind 1170 is designed and engineered to a world-class standard.

Large opening windows and hatches, combined with 6′ 6″ headroom in the saloon and staterooms, ensure incredible views and superb ventilation throughout the boat.
With the cockpit doors up, you’re afforded unparalleled space for onboard living and entertainment.
All lines run back to the cockpit offering safety, shade and comfort in all conditions, while the cruising mini-keels protect the inboard diesel sail drives and spade rudders.
