The double hull of a submarine is different from a ship's double hull. The external hull, which actually forms the shape of submarine, is called the outer hull, casing or light hull. It defines the hydrodynamic performance of submarine, which affects the amount of power required to drive the vessel through the water.
Single hull, Double bottom, and Double hull ship cross sections. Green lines are watertight; black structure is not watertight. 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 ...
A multihull is a boat or ship with more than one hull, whereas a vessel with a single hull is a monohull. The most common multihulls are catamarans (with two hulls), and trimarans (with three hulls). There are other types, with four or more hulls, but such examples are very rare and tend to be specialised for particular functions. [1]
USS Plunger, launched in 1902 Akula (launched in 1907) was the first Russian submarine able to cruise long distances. Commissioned in June 1900, the French steam and electric Narval employed the now typical double-hull design, with a pressure hull inside the outer shell. These 200-ton ships had a range of over 160 km (100 mi) underwater.
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 .

Known as "pig boats", or "boats", due to foul living quarters and unusual hull shape. O-11 through O-16 (built by Lake Torpedo Boat Company) also known as the "modified O-class". Modified boats proved to be disappointing and were scrapped in 1930; Lake went out of business in 1925.
The combination of symbol and hull number identify a modern Navy ship uniquely. A heavily modified or repurposed ship may receive a new symbol, and either retain the hull number or receive a new one. Also, the system of symbols has changed a number of times since it was introduced in 1907, so ships' symbols sometimes change without anything ...
