The towing system for a tugboat consists of a ring arranged on the deck of the tugboat along which a cart moves on which a winch is arranged. At a larger diameter of the ring manufacturing inaccuracies of the cart respectively the ring respectively deformations can be absorbed in a particularly efficient way by arranging springs between the wheels that engage the ring-shaped base and the cart on which the wheels are arranged. In particular, such springs are rubber springs such as neoprene springs. These can be arranged as blocks, bushes or the like. Preferably, the cart includes a relatively stiff box on which a winch and, more in particular, an electrical winch is arranged. In particular, the cart is a ring, extending around circumferentially.
