Abstract: This report deals with the steady hydrodynamic problem of a single-rudder ship moving in a shallow canal of rectangular cross section. The ship-rudder system is considered as a slender body with a hinged fin. The theoretical model can be used to compute the lateral forces induced by the canal walls, the sway angle and rudder deflection required to cancel the effects of these forces, and the course-keeping stability. No numerical results are given here.
