A sea comfort comparison of two large high-speed catamarans is presented. The two vessels have totally different hull forms but approximately the same total displacement and mass distribution. The first vessel is more or less a conventional catamaran, while the second is of a semi-swath type. This paper focuses on the influence of sea environment, onboard location and vessel speed on the sea comfort onboard the two vessels. The effect of motion damping devices on sea comfort is investigated as well. The comfort evaluations are based upon standard ISO curves combined with a hydrodynamic analysis for determining the acceleration levels in different locations on the vessels. Sea comfort analysis features as one element in the Comfor. Class concept recently launched by DNV. Comfort Class also includes other optional elements such as noise and vibration and indoor climate. The main aim of the Comfort Class is to provide a uniform basis for rating of different designs.
