As a first assistant or chief engineer, what is the source of your authority?

Correct Answer: Option A — Your authority is conferred upon you by the license you hold and maritime tradition.

The authority of a licensed officer is derived from the USCG license, which certifies technical competence, and is reinforced by long-standing maritime tradition. This professional standing grants the Chief Engineer the legal and operational mandate to direct engine department activities and maintain the safety of the vessel.
