In this article the authors propose a change in approach when providing information included in maneuvering documents on the squat effect of a ship. The development of ships which is aimed at increasing the loading capacity contributes to the increase of their draft and construction dimensions. This fact renders it necessary to develop ports and to interfere in the bathymetric layer of the basin, i.e. its deepening. However, the under keel clearance along the ship’s route and during the port towing maneuvers is often significantly limited. This makes it crucial to adapt the speed to the sailing conditions. Knowledge of the draft change with a low water level under the keel is important for the safety of navigation. Hence, the authors proposed expanding the maneuvering information contained in the ship's documentation with the additional curve of squat effect presented in the form of polynomial functions.
