Abstract

The paper describes the results of navigation tests on the modernized entrance to the Leba port. The aims of the tests were: - determination of extremed hydrometeorological conditions for the safe entering into the port by the fishing boat type B-410; - determination of maximum size of the ferry for safe steering into the port of Leba. It was caused by modernization of the westerly breakwater to increase the ships safe entering into the port during to NW, W. NE winds. The solution to these problems is based on the computer simulation model of ship's movement and water area. 1 Introduction The port of Leba is situated in the central part of the Polish coast (Slupsk region). It is a fishing harbour and a marina. The arrangement of the entrance breakwaters lying roughly along the N-S axis (see Figure 1) causes, at NW-N- NE winds, the
