Abstract

A very good seakeeping vessel is able to operate effectively even in high sea states and also the passengers and the cargos are ensured in good conditions. The motions of a high speed boats are highly influenced by speed and dynamic forces even in encounter frequencies so that the assessment of seakeeping ability of the design craft in an early stage needs to be calculated for all three motions and for all ralative wave headings. In this paper, it concludes that RAO and RMS values of the catamaran’s 3 motion are calculated according as the variation of Beafort scales and ship’s speed. The ship motion response of the catamaran based on the RAO and RMS by encounter angles and speed was calculated.
