Abstract
A vent for allowing air to move between the interior and exterior of a shrink film envelope enclosing a vehicle, such as a boat, aircraft, etc., or some other object comprises a generally flat vent plate. The vent plate has oppositely facing interior and exterior surfaces and includes both a central portion and a peripheral portion. An array of holes extends through the central portion of the plate to establish fluid communication between the interior and exterior surfaces. Deflectors are positioned on the exterior plate surface for shielding the holes to inhibit entry through the holes of liquids while allowing generally unrestricted air circulation between the envelope interior and exterior. In one embodiment, the deflectors comprise an array of cowls with an individual cowl for shielding each hole of the array.
