Are standing orders, navigation standards, OIC night orders, and XPO morning orders required by regulations?

The reason why the correct answer states that standing orders, navigation standards, OIC night orders, and XPO morning orders are required by regulations is because these items are essential for the safe and efficient operation of a vessel. According to the Coast Guard’s regulations outlined in CIM 5000.3B, these orders ensure that there is clear communication of expectations and responsibilities for bridge watch personnel.

These documents help to standardize operations and provide a framework within which mariners must operate. They are particularly important during times of reduced visibility or at night when the risks of navigation are heightened. By having these established orders, it ensures that watch standers are aware of their duties, any special considerations for the vessel’s operation, and protocols to follow, which ultimately contributes to the safety of the vessel and crew.

In contrast, the other options suggest that these orders might be optional or only required under specific circumstances, which does not align with the emphasis that the Coast Guard places on maintaining high standards for vessel safety and operational efficiency. The overarching requirement for these orders across all types of vessels, rather than just commercial or during specific operations, further underscores their importance in maritime operations.
