This article presents a new innovative method to reduce the motions and stabilizing the ships using the ordinary fishing net. The study of ship motions in the waves has been the main concerns of ship designers. Some methods have been used to stabilize the ship in the waves, such as stabilizing tanks, gyro stabilizers and fin stabilizer, which these have their own advantages and disadvantages. In this paper, the study of the net element to reduce the amplitude of Pitch motion in the regular waves in the static state has been done by experiments in a towing tank. The model experiments were performed in the towing tank of National Iranian Marine Laboratory (NIMALA) using two kinds of net with different meshes to compare the effects. The innovative idea of using the fishing net element to reduce the ship motions in the waves was presented for the first time in this research. The findings of this study for the planing craft show a reduction in Pitch motion of up to 20% in regular waves. The length of the model is 2.5 meters and the requirements of the test method are based on the ITTC marine testing instructions.
