WebHull (watercraft) A hull is the watertight body of a ship, boat, 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. The line where the hull meets the water surface is called the ... WebMay 9, 2024 · The bottom of the boat matters at least as much as the chine, basically a hull is an overall design formula. Deep V hulls with hard or reverse chines can rock severely and wildly. Other hulls that have round chines and come fairly flat astern can be more stable. You got weight and the distribution of it in there too. WebHull form parameters studied include length-to-beam ratio, displacement-length ratio, longitudinal position of the center of gravity and section shape (hard chine or round bilge).
