The marine vessel deck ventilator has a cap (12), with a sidewall formed with a window next to the deck. A common wall formed with an orifice (22) divides the cap interior into two chambers, one of which communicates with the window and the other of which has a ventilator duct (7). One chamber encloses a hinge for a pivoted closure (30) which can open or close the orifice in the partition, being biased toward the open position. A float is integral with the closure and biases it toward a closed position when water enters the chamber.
