When the dew point of the outside air is higher than the dew point of the air in the cargo hold, you should __________.

Correct Answer: Option B — not ventilate the cargo holds

Ventilating with outside air whose dew point exceeds the hold dew point introduces moisture, raising the risk of ship sweat or cargo condensation. Standard marine ventilation rules dictate keeping holds sealed when outside dew point is higher than internal dew point.
