WebUniversity of Hawaiʻi (UH) Marine Center operates the research vessel, R/V Kilo Moana, a 186' SWATH (Small Waterplane Area Twin Hull) vessel and coordinates the maintenance and operations of the Remotely Operated Vehicle (ROV), Luʻukai, capable of diving to 6000 m, as well as several ocean gliders used by C-MORE, HOT, and other programs. WebA Small Waterplane Area Twin Hull, better known by the acronym SWATH, is a catamaran design that minimizes hull cross section area at the sea's surface. Minimizing the ship's volume near the surface area of the sea, where wave energy is located, minimizes a vessel's response to sea state, even in high seas and at high speeds. The bulk of the displacement … smallwoods custom framed pictures

A small waterplane area twin hull, better known by the acronym SWATH, is a catamaran design that minimizes hull cross section area at the sea's surface. Minimizing the ship's volume near the surface area of the sea, where wave energy is located, minimizes a vessel's response to sea state, even in high … See more The twin-hull design provides a stable platform and large, broad decks. Compared with conventional catamarans, SWATH vessels have more surface drag, but less wave drag. They are less susceptible to wave … See more • Duplus (1969): oil industry support ship, the first SWATH ship built • Sea Shadow (1984): US Navy experimental stealth ship • CCGS Frederick G. Creed (1988): Canadian Coast Guard survey ship See more The SWATH form was invented by Canadian Frederick G. Creed, who presented his idea in 1938, and was later awarded a British patent for it in 1946. The first full-scale SWATH vessel to be built and put into service was MV Duplus, a diving support … See more • Multihull – Ship or boat with more than one hull • M80 Stiletto – Prototype naval stealth vessel • Catamaran – Watercraft with two parallel hulls of equal size See more WebBeing that SWATH is an acronym of Small Waterplane Area Twin Hull, such vessels typically have two submarine-like lower hulls which run completely submerged.
