Question 455 Deck General

The correct answer is D) the entire steering gear be tested within 12 hours prior to departure. Regulations require that on vessels making voyages longer than 48 hours, the entire steering gear system must be tested within 12 hours prior to departure. This is to ensure the proper functioning of the critical steering system before the vessel sets out on an extended voyage. The other options, while important safety practices, are not the specific regulatory requirement for vessels on long voyages. For example, testing the emergency generator and lighting or conducting lifeboat drills are general safety measures, but do not directly address the steering gear requirement for extended voyages.
