Considering resistance is a vital factor during ship design, especially when the vessel navigates through shallow waters. This situation leads to increased hull pressure as the ship advances. The ship can increase sinkage and trim, affecting the total drag of the vessel. It is important to predict resistance in water conditions with different surface heights accurately. This study aims to analyze the resistance at sea level. Testing the X-bow shape on the bow is predicted to affect the resistance analysis results. This study predicts ship resistance using the overset mesh technique in the Computational Fluid Dynamics method. According to the study's findings, utilising Ulstein X-Bow in deep water may reduce the total resistance value by 4.85%, followed by a change in sinkage angle by 2.32% and trim by 0.40%. Unfavourable outcomes are shown by the overall resistance value in moderate shallow water situations, and this happens as a result of the squat phenomenon, which is caused by a drop in pressure along the ship's bottom interacting with the water.
