Abstract: A wind scoop for ventilating the enclosed interior area of a boat through a hatch opening thereof is disclosed. The wind scoop comprises a flexible sail for continuously directing an air flow into the hatch opening independent of the direction of the boat with respect to the wind, a mast for rotatably supporting the sail above the hatch opening, and fasteners for holding the mast to the boat above the hatch opening. A wing mechanism responsive to changes in the direction of the wind for changing the orientation of the sail and a swivel mechanism for rotating the sail on the mast are also disclosed. An auxiliary scoop for mounting within the boat to further direct air flow within the boat, and a rain cover for mounting above the wind scoop may be provided.
