Nautical Term: Dead rise
Definition of Dead rise
The term dead rise refers to the upward curvature of a ship’s underbody, extending from the keel to the bilge. This rise serves a crucial function by facilitating the drainage of oil or water towards the center of the ship.
For instance, during heavy rainfall, the water accumulated on the deck of a ship could cause potential hazards. In such situations, the dead rise of the ship’s underbody plays a critical role in efficiently draining the accumulated water towards the centerline of the ship, thereby reducing the risk of potential mishaps.
