How many days to promulgate Nav standards when assuming command?

• A. 30 days
• B. 60 days
• C. 90 days
• D. 120 days

Answer: (C)

Promulgating the ship’s Nav standards within 90 days of assuming command sets the baseline for how the crew should operate, ensuring clear expectations on safety, discipline, and day-to-day procedures. This window is long enough to review current policies, align them with higher regulations, consult department heads, and publish formal directives, while still being early enough to establish guidance before routines become firmly固定.

Starting too soon—within 30 or 60 days—can lead to rushed changes or incomplete input from key stakeholders, resulting in policies that aren’t well coordinated or fully understood. Waiting too long—around 120 days—leaves the crew without authoritative guidance during a vulnerable transition, which can breed confusion and inconsistent practice. Once these standards are promulgated, they provide the framework for training, watch standing, safety, and accountability, so everyone knows what’s expected and how to act in daily operations and emergencies.
