This study examines the characteristics of utilizing pilot charts for navigating ships through narrow waterways characterized by intensively changing current parameters. It analyzes factors influencing the navigational environment, including hydrographic and hydrodynamic conditions that determine the complexity of ship maneuvering. It is demonstrated that traditional pilot charts provide averaged representations of currents and seabed topography, limiting their relevance in rapidly changing hydrodynamic environments. Methods for enhancing the depiction of hydrodynamic parameters on pilot charts are proposed, including the integration of data from hydrometeorological stations, the use of tidal current atlases, and the implementation of dynamic cartographic elements. Recommendations for navigational practices are developed, advocating for comprehensive chart analysis, real-time data updates, and increased collaboration with pilot services. The conclusions and recommendations presented aim to improve the safety and efficiency of navigation in narrow channels with variable currents.
