Abstract

A traction arrangement for a tug boat having a towing winch mounted on the aft and/or fore deck and a tow rope connected to the winch and connectable to a vessel being assisted for necessary measures, such as towing, arresting, steering and equivalent. In order to enhance the stability of the tug boat and the towing, steering, arresting and equivalent properties achieved with the tug boat for the vessel to be assisted, the traction arrangement includes a tow arc mounted essentially in a plane of the deck within an area defined with a transverse bulwark in the front part of the front deck of the tug boat or in the rear part of the aft deck. To be mobile along the tow arc, a towing eyelet is arranged, and through which the tow rope from the towing winch passes to the vessel to be assisted. Traction power is transmitted to the tug boat, and which towing eyelet is on each occasion arranged to be positioned according to the towing angle.
