ABSTRACT:
A ventilator for attachment to a conventional deck hatch. The ventilator has a top panel which abuts the open cover of the deck hatch so that the top panel slopes upwardly from the deck. First and second triangular side panels extend downwardly from the side edges of the top panel to the deck, and an outer front panel extends downwardly from the upper edge of the top panel to a lower edge which is a spaced distance above the deck. An inner front panel extends upwardly from the deck, and is sloped inwardly so that its upper edge is higher than, and is spaced inwardly from, the lower edge of the outer front panel, forming a passage for the entry of air. The overlap between the two front panels eliminates any direct path by which rain or sunlight could pass into the boat through the hatch opening. The panels are fabricated of waterproof cloth, and the top and outer front panels are formed with pouches which receive rigid plates; when the hatch cover is raised, it abuts the underside of the rigid plate in the top panel and raises this at an angle to the deck. A bead of welting is stitched to the lower edges of the panels at the base of the ventilator, and this is retained in a hold-down track which is mounted to the deck of the craft.
