Skidding on the sea is a special form of maritime-navigation activity, consisting in that a boat that tugs (a tractor) puts on a towed ship or other facility at its disposal its driving force by pulling it, pushing it, holding it in a certain place or assisting it in performing other maneuvers. With the tug of war, the tugboat undertakes to sail or push another boat or object to a certain place or for a certain time or to carry out a particular task, and the carrier of the tugged or suppressed vessel undertakes to pay the tug of war. The height of the barge is determined by the hoisting contract. Relationships from the contract of stripping and suppression are regulated by the provisions of the Maritime Code. It is considered, unless otherwise contracted, to be towed by the commander of a towed ship. The aim of dragging is to facilitate the maneuvering of ships where it is difficult, especially in ports or for the transport of a navigable object that is unable to run. This paper gives an overview of the haggling contract with all the specific relationships that arise from this legal transaction.
