Question 3911 Deck General

The correct answer is D) All of the above. Insufficient space between the hull and the bottom in shallow water will prevent normal screw currents, resulting in: 1. Sudden sheering to either side, as the restricted water flow disrupts the normal hydrodynamics of the propeller, causing unpredictable steering response. 2. Sluggish rudder response, as the limited water flow reduces the effectiveness of the rudder in providing directional control. 3. Waste of power, as the propeller has to work harder to overcome the restricted water flow, reducing the vessel's efficiency and fuel economy. The other options are incorrect because they each only describe one of the three effects, while the correct answer encompasses all three consequences of insufficient underkeel clearance in shallow water.
