The principal aim of navigation is to conduct a ship safely and effectively to her destination. Ship's movement in an area is mainly restricted by the area dimensions (length, width and depth). These restrictions make it necessary to choose an appropriate ship movement trajectory. In some cases a navigational accident may occur. This undesired event may result in such consequences as loss of human life or injuries, damage to or loss of ship and cargo, environment pollution, damage to port structures or a blockade of the port or its part, and rescue operation costs. The losses can sometimes be disastrous, when, for instance, a tanker fully laden with crude oil sutlers damage and a major spillage takes place. In order to ensure the safety of navigation of a ship, its trajectory has to be properly chosen. The trajectory is defined by a ship's manoeuvring line path, an area of water required for the ship to move safely. The size of manoeuvring line depends on many factors. The major ones include positioning accuracy, ship manoeuvring characteristics and the phenomenon of canal effect, which consists in shore and bottom affecting the ship's hull. The most important factor is ship positioning accuracy. This is related to aids to navigation that are implemented in various ways. Principal systems used in ship positioning are based on navigational marking, radionavigation (local systems, GPS, DGPS and radio detection (radars). The higher positioning accuracy, the safer is the navigation. This article discusses problems connected with the accuracy of ship positioning in the approach channel leading to harbours located in the region of West Pomerania.
