Abstract
Nonlinear dynamic problems for a floating body anchored by an inhomogeneous cable are solved using a discrete elastic-thread model. The body, which is imponderable in water, stabilizes when suspended at the center of buoyancy via a hinged joint. The studies carried out for a particular example reveal that the approach we use to stabilize the body against angular oscillations does not always minimize the perturbations introduced by the tugboat under rough-water conditions. Also, we obtain conditions under which the body moves steadily and demultiplex resonances are absent.
