This study examines the theoretical and practical aspects of justifying methods to prevent the risk of vessel drift during navigation in shallow waters subjected to dynamic draft changes. The objective was to refine calculation methodologies and develop recommendations for selecting speed, course, and the application of additional maneuvering aids. The research is based on the analysis of hydrodynamic models, laboratory test data, and field observations. Approaches for integrating numerical calculation results with empirical data into navigational practices are proposed. Factors influencing vessel behavior in limited depths are considered, and justifications for corrective measures aimed at minimizing uncontrolled lateral displacement are provided. Additionally, directions for optimizing route planning considering draft fluctuations are identified. The proposed solutions enhance the safety and predictability of vessel handling in complex navigational conditions.
