The master of a small vessel fitted with loading doors must ensure that the doors are closed, watertight and secured when underway in unprotected waters.

• A. True
• B. False
• C. Only On Days With Rough Seas
• D. Only If Doors Are On Port Side

Answer: (A)

When a vessel is moving in unprotected waters, openings like loading doors can allow water to surge onto the deck and into the hull. If these doors aren’t closed, watertight, and secured, water can enter and threaten buoyancy and stability, potentially leading to flooding or loss of control. The master must ensure these doors are kept closed and watertight whenever the vessel is underway in such areas to maintain safety. This requirement applies regardless of sea conditions or which side the doors are on, so the statement is true.
