... resistance in all states is quite challenging. The light weight and at underwater part of the hull indicate a planing yacht. Therefore, when a certain speed has been reached, a considerable portion of the weight is supported by the hydrodynamical lift acting on the at bottom. For the bare hull of the lake...

An outline of the FloSim method is presented; it is an unsteady, time-stepping code with a coupled integral boundary layer analysis for viscous effects such as skin friction resistance and boundary layer displacement effect. The free surface wave development uses a non-linear mixed Eulerian...

... of added resistance in waves. Non-linearity attitudes such as surfing can be investigated. Free-running model testing is a technique frequently used in the development of power vessels, but little adoption is made in the sailing yacht world. Furthermore dynamic and seakeeping studies are at present...
