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 seas and at high speeds. The bulk of the ...
RV Kilo Moana (AGOR-26) is a small waterplane area twin hull (SWATH) oceanographic research ship owned by the US Navy and operated by the University of Hawaii as a part of the U.S Academic Research Fleet and a member of University-National Oceanographic Laboratory System (UNOLS). [1] She was designed to operate in coastal and blue water areas.
Since 1899, the United States Coast Guard Yard has built, repaired and renovated ships for the U.S. Coast Guard. It is the service's sole shipbuilding and major repair facility. The Coast Guard Yard was established on the shores of Arundel Cove off of Curtis Creek and Curtis Bay in south Baltimore, Maryland and neighboring northern Anne Arundel ...
Waterplane coefficient (C w) is the waterplane area divided by L WL x B WL. The waterplane coefficient expresses the fullness of the waterplane, or the ratio of the waterplane area to a rectangle of the same length and width. A low C w figure indicates fine ends and a high C w figure indicates fuller ends.

Sea Fighter (FSF-1) is an experimental littoral combat ship in service with the United States Navy. Its hull is of a small-waterplane-area twin-hull (SWATH) design, provides exceptional stability, even on rough seas. The ship can operate in both blue and littoral waters. For power, it can use either its dual gas-turbine engines for speed or its ...
Baltimore’s Francis Scott Key Bridge crumpled at the impact of the Dali shipping container a gross tonnage of 95,000 on Tuesday morning. The bridge, constructed in 1977, didn’t stand a chance ...
Multihull designs may have hull beams that are slimmer at the water surface ("waterplane") than underwater. This arrangement allows good wave-piercing, while keeping a buoyant hydrodynamic hull beneath the waterplane. In a catamaran configuration this is called a small waterplane area twin hull, or SWATH.
