Their particular area of proliferation is in short sea shipping where they show considerable superiority over competitive designs in attributes such as power requirements, economy, space availability, and sea keeping quality. The rapid growth of the market has led to the need for an expanded range of multihull designs in terms of size, speed, and payload diversity (passengers, vehicles, containers). However, even now there is a scarcity of publicly available preliminary design tools for multihull vessels. This fact hin- ders the ship owner and naval architect from being able to quickly assess the relative merit of alternative potential designs without having to resort to expensive expert consultancy solutions. INTRODUCTION Resistance characteristics and power requirements are principal aspects of the multihull design spiral as they are strongly coupled with speed and fuel economy, and, consequently, the operating and cost efficiencies of the vessel. Saving fuel cost is a big economic motivation and naval architects have been creative about producing hull shapes for minimum resistance. In a complementary way, propulsion systems have been made more and more efficient through better knowledge of hydrodynamics. Both of these approaches reduce the amount of fuel burned and in turn reduce the I.
