The Master or person-in-charge of an OSV shall insure that each deck from which rescue boats are launched is __________.

Correct Answer: Option B — kept clear of any obstructions that would interfere with launching

46 CFR 131.890 mandates that decks used for launching rescue boats on Offshore Supply Vessels must be kept clear of obstructions. This ensures the crew can deploy life-saving equipment rapidly during an emergency without tripping hazards or physical barriers impeding the safe and efficient launch of the boat.
