A containership is scheduled to depart the Port of Houston, TX at 0600 on April 7th on a voyage to exceed 48 hours. What is the EARLIEST time that the steering gear could be tested prior to getting underway and be in compliance with the cargo and miscellaneous vessel regulations of 46 CFR?

Correct Answer: Option C — 1800 April 6th

Per 46 CFR 164.25, steering gear must be tested within 12 hours prior to departure for vessels on voyages exceeding 48 hours. Since the vessel departs at 0600 on April 7th, the earliest valid testing time is 1800 on April 6th, ensuring the system is verified immediately before operations.
