A double hull is a ship hull design and construction method where the bottom and sides of the ship have two complete layers of watertight hull surface: one outer layer forming the normal hull of the ship, and a second inner hull which is some distance inboard, typically by a few feet, which forms a redundant barrier to seawater in case the ...
[22] [23] In modern terminology, especially in leisure or sport boating, double-outrigger ships are usually termed trimaran or triple-hull ships. An unusual type of double-outrigger boat design, preserved in scale models in the Pitt Rivers Museum, forms a triangle shape. The front ends of the outriggers are attached directly to the hull, while ...
The double-hulled Polar Endeavour. Although double-hulled tankers reduce the likelihood of ships grazing rocks and creating holes in the hull, a double hull does not protect against major, high-energy collisions or groundings which cause the majority of oil pollution, despite this being the reason that the double hull was mandated by United States legislation.

A hull is the watertight body of a ship, boat, submarine, or flying boat. The hull may open at the top (such as a dinghy ), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures , such as a funnel, derrick, or mast .
Most newer tankers are double-hulled, with an extra space between the hull and the storage tanks. [4] Hybrid designs such as double-bottom and double-sided combine aspects of single and double-hull designs. [4] All single-hulled tankers have been phased out as of 2015, in accordance with amendments to Annex I of the MARPOL Convention. [4]
Drua, also known as na drua, n'drua, ndrua or waqa tabu ("sacred canoe", Fijian pronunciation: [waᵑɡa taᵐbu]), is a double-hull sailing boat that originated in the south-western Pacific islands. Druas do not tack but rather shunt (stern becomes the bow and vice versa).

There was a double hull running the entire length of the ship. [5] The standard displacement of the ship was specified at 1,600 tonnes, with a full displacement according to various sources of either 1,950 or 2,000 tonnes. [a] After reconstruction, the full displacement decreased to 1,800 tonnes. [15]
