Your vessel is going from a warm climate to a cold climate with a hygroscopic cargo. Which statement is TRUE?

Correct Answer: Option D — You must ventilate constantly and vigorously to combat ship sweat.

Transitioning from warm to cold climates lowers the vessel's hull and deck temperatures. Hygroscopic cargoes release moisture into warm hold air; as the ship's skin cools, this moisture condenses, demanding vigorous and continuous ventilation to prevent cargo sweat.
