Question 19 AB01 - Able Seafarer

The Correct Answer is B **Explanation for Option B (Correct Answer):** In standard maritime terminology used by helmsmen, the command "shift the rudder" or "shift your rudder" is a direct instruction for a significant change in steering angle. It means the rudder currently deployed on one side (e.g., 10 degrees right) must be immediately moved to the equivalent position on the opposite side (e.g., 10 degrees left). This maneuver is typically used to rapidly counter excessive swing or initiate a quick turn in the opposite direction without having the Master or Officer of the Watch calculate and state the specific opposite angle. **Explanation of Incorrect Options:** **A) Stop the swing of the ship.** While shifting the rudder is often done to counter or stop a swing, the command itself describes the action to be taken with the rudder, not the desired navigational outcome. Stopping the swing might require only a small opposite rudder, whereas "shift the rudder" demands a full, mirroring movement. **C) Shift the rudder control to the alternate steering method.** This action is referred to by commands such as "switch to non-follow-up (NFU) steering," "change over to emergency steering," or "transfer control to [location]." "Shift the rudder" pertains only to the physical positioning of the rudder itself. **D) Put the rudder amidships and hold the heading steady as she goes.** The command to place the rudder at 0 degrees is "rudder amidships." "Shift the rudder" requires putting the rudder hard over to the opposite side, not bringing it to neutral.
