Catamarans are the most accepted form of high speed craft for passenger/vehicle transportation. In this study, the two-dimensional potential theory associated with a cross-flow approach for taking viscous effects into account for estimating the small amplitude motions in the frequency domain has been validated by experimental results of three catamarans. The two-dimensional method calculations can provide reasonable predictions of motion responses of catamarans at low forward speed. There are some discrepancies observed in the prediction of pitch motions in the low wave frequency region. Through the experimental investigation of the V-1 catamaran model with variable forward speeds and wave amplitudes, it can be confirmed that the non-linear effects become significant when the model speed and wave amplitudes increase. The peak values of heave and pitch motions measured around the resonance are smaller than those obtained from the small apmlitude motion predictions. Because of the linearised boundary value assumption, the frequency domain method will be restricted to the prediction of small amplitude motions.
