Abstract
New slender-ship theory is widely used in the calculation process of wave resistance, which has been developed in the past decades. In this paper, taken trimaran as example, based on modified Noblessis slender ship theory, where the variables are separated by expanding exponential function, the trimaran's wave resistance kochin formulae is established. The wave resistance can be calculated rapidly with these formulae. The numerical results coincide well with that of the model test. So the feasibility of the new slender ship wave resistance theory is proved and can be applied to calculate the high-speed multi-hull's wave resistance.
