Insufficient space between the hull and bottom in shallow water will prevent normal screw currents resulting in __________.

Correct Answer: Option D — All of the above

Shallow water restricts the flow of water to the propeller and rudder, causing bank suction and cushion effects. This interference with normal screw currents leads to sluggish rudder response, increased power consumption, and unpredictable sheering, which significantly complicates vessel handling and increases the risk of grounding or collision.
