<p>The present invention relates to a tug boat intended for escort towing and/or harbour use, being provided with a towing winch (22) positioned at least on the forecastle. The tug (40) is intended, while in escort towing, to improve at high speed the steering and arresting properties of a vessel to be as-sisted by means of a tow rope (21) emitted from the towing winch (22) and connected to the vessel being assisted. In harbour use, the tug boat (40) can be applied for ordinary towing aand buffer tasks. In order to improve the stability of the tug boat (40) and the towing, steering, arresting and equivalent properties provided with the tug boat in the vessel being assisted, a towing eyelet (24) through which the traction force of the tow rope (21) connected from the towing winch (22) of the forecastle to the vessel being assisted is transmitted to the tug boat (40), has been arranged to be positioned, in accordance with the towing angle, to the proximity of the deck plane or in the deck plane. The hull of the tug boat (40) has moreover been so designed that the hydrodynamic point of application of the hull is brought up and to the front of the adjacency of the towing eyelet (24) to reduce the torque heeling the tug boat (40) and to bring the rope force and the hydrodynamic force longitudinally close to one another. <IMAGE></p> |
