Definitions

  • the seagoing properties of the hull configuration of the invention are improved, such that the hull's pitching and heaving movements are reduced compared to the movements of conventional hulls traveling at the same rate of speed, and these movements are also retarded such that the improved hull does not exhibit correspondingly large movements until the wave length/hull length ratio is more than twice as large, while at the same time the improved hull's resistance to propulsion is reduced to a similar degree.
