Question 3780 Deck General

The correct answer is C) Prior to getting underway. The reason this is the correct answer is that Coast Guard regulations require the fore and aft draft readings to be recorded in the vessel's unofficial logbook prior to getting underway. This is done to document the vessel's draft and ensure it is within safe operating limits before commencing a voyage. The other answer choices are incorrect because they do not align with the regulatory requirement. Readings once a week (A) or once a day (D) are not specifically mandated, and only recording them when changing water densities (B) does not cover the full scope of the regulation.
