Evaluation of the Kinetic Performance of a High-Speed Planing Vehicle

Abstract

In recent years, high-speed vessels such as passenger ships, fishing boats, and pleasure boats, have been operated in various applications. In Japan, the method of towing test, the characteristics of hydrodynamic forces acting on the hull, and the kinetic characteristics during running in waves have been studied on many occasions particularly for high-speed planing vessels and semi-planing vessels. However, in foreign countries, high-speed rectangular-shaped vessels that have a large flap at the fore part of hull, such as Expeditionary Fighting Vehicles (EFV, hereafter), have been researched in addition to vessels used for business and leisure applications. Unlike in general high-speed vessels that have been actively studied so far, various assignments are left unclarified in the research of EFV, for example, the kinetic characteristics during high-speed running, the characteristics of hydrodynamic forces acting on the hull, and so on.
