"Lose The Rock & Role"

A Small Waterplane Area Twin Hull, better known by the acronym SWATH, is a twin-hull ship design that minimizes hull cross section area at the sea's surface. Minimizing the boats volume near the surface area of the sea, where wave energy is located, maximizes a vessel's stability, even in high seas and at high speeds. The bulk of the displacement necessary to keep the ship afloat is located beneath the waves, where it is less affected by wave action. Wave excitation drops exponentially as depth increases, so wave action normally does not affect a submerged submarine at all. Placing the majority of a ship's displacement under the waves is similar in concept to creating a ship that rides atop twin submarines.

 The twin-hull design provides a stable platform and large, broad decks. Compared with conventional catamarans, SWATH boats have less wave drag, they are less susceptible to wave motion. The design building of SWATH vessels is also considerably more complex due to the structural complexities inherent to the design. Making SWATH vessels the preserve of oceanographic  institutes and the worlds navy's. Our revolutionary modular design combined with advances in composite materials and hydraulic propulsion now mean SWATH is a viable alternative for leisure boats and coastal commercial vessels.
