what part of the ship is the hull
Hull (watercraft) The hull is the watertight body of a ship or boat. Above the hull is the superstructure and/or deckhouse, where present. The line where the hull meets the water surface is called the waterline.
HMS Surprise (replica ship) The ship was sold to the 20th Century Fox film studio in March 2001,[9] and underwent extensive modifications to be used in the making of the film Master and Commander: The Far Side of the World, in which she portrayed the Royal Navy frigate Surprise with a story based on several of the books by Patrick O'Brian. The modifications included a reshaped stern, all deck structures removed, the single ship's wheel replaced by a double wheel, period fighting tops fitted, new sails, and the figurehead replaced.[10]
