Abstract

PURPOSE:To prevent the eddy current produced in a trim tab by bending at least the front end side of the trim tab positioned at the rear of the propeller to follow the water flow to be formed by the rotation of the propeller when advancing. CONSTITUTION:A trim tab 14 for assuring the linear advancing performance of a hull is fixed through a screw 19 penetrating through the inner wall 18 of a lower casing 6 to be screwed on a supporting projection 16 in a recess 13 formed at the tail section 12 of the casing 6. The trim tab 14 is constructed such that the direction can be varied freely by loosening the bolt 19 while bent along the flow produced by the propeller 10.
