![]() ![]() ![]() But in reality, boats get into trouble a lot sooner than that. Logically, this would happen when her decks have gone past vertical and the center of gravity falls outside the center of buoyancy-the 'zero-moment' point. Since most of the hull weight is represented by the keel bulb (typically more than 80 of the total weight), a righting moment is produced whenever the yacht. ![]() Righting moment is the torque trying to return a boat into equilibrium. But that definition does not help in judging which boat has more of that, which has less of that. A Righting Moment is created by the ship to keep itself upright. Finally, there always comes a point where the boat can no longer right herself. Their definition of stability is more or less 'the ability of the boat to keep You out of water'. The lower the metacentric height, the less leverage there is with which to overcome the downward force of gravity. The high center of gravity reduces what is called the metacentric height, which determines the length of the righting arm. (More air is submerged as she heels over, so the righting arm is that much longer.) The opposite is also true: The taller the ship, the more likely she is to capsize. First of all, the wider the ship, the more stable she is. "The righting moment has three main implications. They want something that will right them from extreme angles of heel. To greatly simplify, the lateral distance between the two forces is called the righting arm, and the torque they generate is called the righting moment. The raised water level on the upstream edge or heel will also. The rising water will cause hydrostatic force which will tend the dam to slide horizontally and overturn about its downstream edge or toe. "The more the ship heels, the farther apart the two forces act and the more leverage the center of buoyancy has. Dams are structures whose purpose is to raise the water level on the upstream side of river, stream, or other waterway. Chained_bear commented on the word righting moment ![]()
