Question 3887 Deck General

The correct answer is A) You may lose rudder control until the ship's speed has dropped to correspond to propeller speed. When decreasing pitch on a right-handed controllable-pitch propeller, the reduced propeller thrust can cause a temporary loss of rudder effectiveness until the ship's speed has decreased enough to match the lower propeller speed. This is because the rudder relies on water flow over it to generate the necessary forces for steering. With a sudden drop in propeller thrust, the water flow may become disrupted, leading to a temporary loss of directional control. The other options are incorrect because they do not accurately describe the physics and mechanics involved in this situation.
