What the fleet has seen

The Seawind 1370, as the fleet has seen it

Derived from the videos the fleet has analysed of this model. ▶ marks open the moment aboard.

The Seawind 1370 is a 13.7-meter fractional sloop catamaran, designed by Francois Perus and Yacht Design Collective, and built by Seawind Catamarans since 2020. It features a twin-keel hull, a 7.6-meter beam, 1.3-meter draft, and displaces 11,000 kg. The owner's version includes a dedicated workshop, a walk-around bed, and a twin-helm configuration. Aboard Gone with the Wynns, the boat maintained 8.2 knots at 66 degrees apparent wind in 26-knot gusts during a passage in Thailand.3:47 The twin helms offer protection and visibility, but require headsets for close-quarters maneuvering due to cabin windows blocking external sound. The design provides significant interior volume, though some crews find the laminated aesthetic stark.29:15 The Seawind 1370 has a bridge deck clearance of 33 inches, which is higher than many cruising catamarans like the Lagoon 450 and Lagoon 42, but less than the Leopard 48.4:36
