WebAug 15, 2016 · Parametric modeling was applied to the hull by using non-uniform rational basis spline (NURBS). The Rankine-source panel method was used to calculate the wave-making resistance. A hybrid optimization strategy was applied to achieve the optimization goal. ... (USV) and small waterplane area twin hull (SWATH) . 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.
