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.
