The paper summarises an experimental investigation into the correlation of model scale wave wake measurements against full scale trials results for a catamaran operating at low length Froude numbers. Both full scale and 1/9lh scale model experiments were conducted over the range of sub-critical length Froude numbers of approximately 0.1 to 0.3 (full scale speed range of4 to 8 knots). The results of the investigation confirm that a correlation factor of close to unity be applied when using model scale experimental data to predict full scale maximum wave heights for catamarans operating within such a speed range. It was also found that the scale model tests slightly over predict the period of the maximum wave, generally by around 5%. Consequently, it is expected that the energy of the maximum waves can also be accurately predicted from model scale data. The paper also provides useful guidance notes for the conduct of full scale wave wake experiments.
