Wave-making resistance is a form of drag that affects surface watercraft, such as boats and ships, and reflects the energy required to push the water out of the way of the hull. This energy goes into creating the wave. See more For small displacement hulls, such as sailboats or rowboats, wave-making resistance is the major source of the marine vessel drag. A salient property of water waves is dispersiveness; i.e., … See more Since wave-making resistance is based on the energy required to push the water out of the way of the hull, there are a number of ways that this can … See more • Ship resistance and propulsion • Hull (watercraft)#Categorisation • Hull speed See more Since semi-displacement and planing hulls generate a significant amount of lift in operation, they are capable of breaking the barrier of the wave propagation speed and operating in realms of much lower drag, but to do this they must be capable of first pushing past that … See more WebIn this study, the purpose is the estimation of ship wave resistance using different scale model ship's data included the actual ship data recorded in real sea.
