Question 252General Subjects - 1st Asst/Chief

The correct answer is C) Operation of the alternative power supply for the steering gear, if the vessel is so equipped. The reasoning for this is that the regulations in 33 CFR require vessels to conduct drills that test the operation of the alternative power supply for the steering gear, if the vessel is equipped with one. This is to ensure the vessel can maintain steering control in the event of a main power failure. The other options, while important for overall vessel safety, are not specifically required as part of the drills prior to entry into the port of Charleston under the 33 CFR regulations. The operation of the main steering gear and communications between the bridge and steering compartment are important, but not directly mandated for these particular drills.
