Abstract
    In this paper we discuss two basic problems in shallow water ship hydrodynamics, namely the squat problem and the problem of wave force due to beam seas. Squat is an important phenomenon in very shallow water because of the danger of scraping bottom. Apart from reviewing and extending existing work on sinkage and trim in canals and in a wide expanse of shallow water, we indicate here how the shallow water results can be obtained from a finite depth theory as the depth becomes small. Unsteady problems associated with motions or of forces on a ship in beam seas are also of practical importance, as for a ship standing at an exposed mooring facility. We provide here sample computations of the side force on a tanker hull in regular beam seas.
