Question 1792 Deck General

The correct answer is C) 12 hours. According to the regulations, the steering gear, whistle, and means of communication between the pilothouse and engine room on a passenger vessel must be tested by an officer of the vessel within a period of not more than 12 hours prior to departure. This requirement is specified in Title 46 of the Code of Federal Regulations (CFR), which governs the operations of passenger vessels in the United States. The other options are incorrect because 4 hours is too short, 8 hours is not the specified timeframe, and 24 hours is too long for the required testing to be conducted prior to departure.
