A tug boat for escort towing and/or harbor use having a towing winch positioned at least on the forecastle. While in escort towing, the tug is intended to improve the steering and arresting properties of a vessel to be assisted by means of a tow rope emitted from the towing winch and connected to the vessel being assisted. In harbor use, the tug boat is applied for ordinary towing and buffer tasks. In order to improve the stability of the tug boat and the towing, steering, arresting and equivalent properties provided with the tug boat in the vessel being assisted, a towing eyelet, through which the traction force of the tow rope connected from the towing winch of the forecastle to the vessel being assisted is transmitted to the tug boat, is positioned depending on the towing angle and in proximity of the deck plane or in the deck plane. The hull of the tug boat is designed such that the hydrodynamic point of application of the hull is brought up and to the front of the adjacency of the towing eyelet to reduce the torque heeling the tug boat and to bring the rope force and the hydrodynamic force longitudinally close to one another.

A tug boat for escort towing and/or harbor use including an elongate hull, a towing winch installed on a deck thereof and a tow rope connected to the towing winch and connectable to a vessel being assisted, comprising a towing eyelet through which the tow rope is passed between the towing winch and connectable to the vessel such that traction force of the tow rope is transmitted to the tug boat through said towing eyelet, said towing eyelet being arranged such that the force transmitted to the tug boat through the tow rope lies in a plane in proximity to or on the deck of the tug boat, and a substantially arcuate tow arc mounted on the deck and arranged in a plane substantially parallel to a plane of the deck, said towing eyelet being movable along said tow arc to change its position relative to a change in a towing angle defined between a longitudinal center line of the boat and a direction of the tow rope extending from the boat to the vessel, the hull having a construction such that a hydrodynamic point of application of the hull is situated in a longitudinal position proximate to said towing eyelet such that torque heeling the tug boat is reduced and the force of the tow rope and the hydrodynamic force are longitudinally close to one another.
