Synonym discussion

Sense: noun/1

Hull is the specific nautical term for the watertight body of a ship or boat. Body is the most general term, used for any vehicle or organism (the body of a car, the human body). Frame refers to the internal skeleton or structural support rather than the outer skin (the frame of the house). Shell emphasises the hard outer casing and is used for eggs, turtles, nuts, or aircraft (the shell of a building). Fuselage is the equivalent of hull for aircraft — the central body that holds passengers and cargo. Unlike hull, fuselage is used exclusively for planes and helicopters. In everyday English, you would say 'the ship's hull was damaged' — not 'the ship's body' or 'the ship's frame', which sound unnatural to native speakers.

Etymology

Old EnglishMiddle EnglishEnglish

From Old English hulu meaning 'husk, pod, or seed covering'. This original sense (the outer covering of a plant) dates back to before the 12th century. By the 15th century, the word was extended metaphorically to describe the outer body or 'shell' of a ship — perhaps because people saw a ship's frame as a kind of large, hollow covering that protects what is inside, much like a nut or seed pod protects its kernel.
