Which risk increases substantially if a ship's propeller operates extensively in shallow water?

💡 Explanation

When a propeller operates in shallow water, flow restriction increases its rotational speed because there is less water for the propeller to 'push' against, promoting tip vortices, leading to cavitation and accelerated erosion. Therefore accentuated propeller cavitation results, rather than corrosion, rudder issues, or cylinder head temperature increase, which do not directly involve flow restriction.
