Abstract: The researched ship is a hybrid monohull based on some round-bilge ship using intilted low-freeboard, wave piercing bow, and longitudinal stability built-up appendage. In this paper, the model test on this new hybrid monohull is researched including resistance test in calm water and seakeeping test in regular and irregular waves. The model test results are compared with the round-bilge original ship and the regular hybrid monohull, and indicate that the resistance performance of the new hybrid monohull is better than the original ship, and the resistance is reduced by more than 3%at 36kns. The seakeeping per-formance is even better, and the pitch amplitude is averagely reduced by 50%. So the sailing performance of the new hybrid monohull is much better than the original round-bilge ship and even better than the regular hybrid monohull.
