70% to pass

You are on a large vessel fitted with a right-handed controllable-pitch propeller set at maximum forward pitch. Which statement about reversing is TRUE?

A When the pitch is reversed, the stern will slew to port even with headway.
B The vessel will have full rudder control throughout the speed change from ahead to astern.
C The vessel will respond to the rudder until sternway is developed, then the stern will slew to starboard.
D There will probably be a loss of steering control.
AI Explanation

The correct answer is D) There will probably be a loss of steering control. When a right-handed controllable-pitch propeller is set to maximum forward pitch, the vessel will have good steering control and response. However, when the pitch is reversed to go astern, the propeller's thrust will be directed to the port side, causing the stern to slew or swing to port. This loss of steering control can make the vessel difficult to maneuver, especially at low speeds. The other answer choices do not accurately describe the vessel's behavior during the transition from ahead to astern with this type of propulsion system.
