Abstract

Medium-speed catamarans are under development as a new class of vessels to meet requirements for highly efficient sea transportation with a low environmental impact. A reduction in service speed and an increase in deadweight will lead to a high transport efficiency. Compared to current high-speed catamarans, these new vessels will operate at a transitional speed range between those of high-speed craft and conventional displacement ships.

In this paper, design guidelines to choose appropriate hull form parameters for medium speed catamarans with minimum resistance are derived and a preliminary design is made. Most important these vessels will operate at Froude numbers of Fr = 0.35 and have a relatively low prismatic coefficient of Cp 0.5 in conjunction with a low transom immersion. To correctly predict the calm water resista.nce, different methods to predict the calm water resistance of such vessels are discussed, whereas viscous free-surface flow simulat ions are most promising. It is shown that they are capable of predicting the hydrodynamic behaviour of mediumspeed catamarans, such as drag force , trim and sinkage within an acceptable range of accuracy.
