Final answer:
In case of a vessel deviating from its course without corrective action from the autopilot, the correct emergency procedure is to switch from autopilot to hand steering to regain immediate and direct control over the navigation of the vessel. Option A is correct.
Step-by-step explanation:
If a vessel deviates from the given course while on autopilot and fails to correct its direction with rudder action, the emergency operating procedure should require you to immediately change operation from autopilot to hand steering. This action ensures direct human control over the vessel's steering, which is critical in maintaining the safety and navigational integrity of the vessel.
The prompt switch to hand steering allows the operator to correct the course manually and address any issues with the vessel's autopilot system. It's important for those operating seafaring vessels to be well-versed in such emergency procedures to respond effectively to technological malfunctions.
When the vessel is deviating from the given course and there is no follow-up with corrective rudder action to return to the proper heading while steering by autopilot, the emergency operating procedure should require an immediate change in operation from Autopilot to manual mode.
This means that the autopilot system will be disengaged and the vessel will be manually steered by the operator. By switching to manual mode, the operator can take control of the vessel and make the necessary adjustments to correct the deviation.
