Preliminary design study to reduce resistance for high speed planing craft

Abstract

The aim of this study is to design a high speed planing craft at the preliminary stage using validated and published mathematical models. The generated high speed planing craft design must be an improvement compared to the basis design. The displacement is fixed as the independent variable and modifications will only be done to the length, breadth and draft of the craft. This study describes a methodology that begins with reviewing literatures on high speed planing craft, followed by data collection and establishing new designs based on the basis design. The hull form and lines plan of the designs is generated using the Maxsurf software. Resistance analysis is performed using the Hullspeed software, while fuel consumption rating and manoeuvring capabilities of the high speed planing craft is analysed using mathematical equations. The best design based on mission requirements is then uncovered.
