The vessel stopping shifts the pivot point forward and creates a turning moment and results in the ship swinging towards the bank.
The hydrodynamic interaction effects from the banks of the shallow water channel acts on the stern causing the vessel to sheer strongly
The large volume of water dragged behind the vessel continues to move forward and cause a strong turning moment on the stern of the vessel
