ABSTRACT:
A ventilator for a covering for a boat or other object includes a dome for covering air venting openings. The air vents are provided in a pair of oppositely disposed ventilator plates. The boat or other covering is firmly clamped between the ventilator plates by means of a nut that can be tightened by hand. The venting openings are disposed one above the other with no obstructions therebetween in order to allow for direct air transfer between the inside and the outside of the cover while preventing weather elements from entering the cover.
