Abstract:

A monohull sailing along a straight course in calm water, of infinite depth and unbounded in the horizontal plane, and being steered by its rudder oscillating harmonically in time, is linearized, based upon thin ship theory. First-order equations serve as the governing equations to describe the yawing motion of a steered ship. The approximate solution of the first-order equations is found by finding a doublet distribution satisfying the rigid free surface. A comparison between the numerical calculation of the approximation and the test data of a 196 scale ship model of Mariner class is made, at two different speeds. Author
