The results are presented in Figures 2 to 10. For each of the figures, Figure a is the heave RAO; Figure b is the heave phase; Figure c the pitch RAO and Figure d the pitch phase.

The Seakeeper results are for a single demihull in isolation. These have been compared with the towing tank data for the two catamaran configurations and the demihull tested in isolation (monohull). It may be seen that for all but the lowest speeds, the interaction between the two catamaran demihulls is small.
