WebJan 15, 2024 · Paul Bruno. Updated on 01/15/20. In terms of boating, the chine is the area of a vessel's hull where the bilge angles up to become the topsides of the hull. The hull … 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 ...

WebJan 1, 2003 · Hull speed is defined as the point where the very crest of the bow wave is at the stem of the vessel and the crest of the stern wave is at the transom – in essence, the vessel is neatly tucked into the trough of a wave of its own creation. To get on a plane requires enough energy to break free of the stern wave and climb onto the crest of the ...

WebFeb 21, 2010 · The rule that I use is that chine width should be about 1.5 to 2% of the maximum chine beam, per side. However, I have designed many boats that exceed this value. With wider chines the boat will roll less at idle or rest, and gives added stability at speed, however, the boat will ride a little rougher with wider chines. WebHull characteristics.
