The effect of ACS on sea-keeping quality of a car and passenger ferry with ACS was investigated on both ship models with soft chine and ‘Deep V’ type hull configuration both with and without ACS. The sea states used in the testing were sea states 4, 5, and 6 for the full-scale ship with displacement 4000 t.

The test results showed that the ACS cavity was not broken down when in the sea states mentioned above, and at all towing speeds of models with air cavity, the heaving and pitching motions could be reduced by 35% to 30%. Meanwhile, the vertical loading coefficient at bow could be reduced by 35%, and in addition, the drag of the model with ACS at all speeds was lower than that without ACS and with smooth hull bottom profile.
