Abstract: The present invention relates to a boat shade comprising a cover and a frame for it formed of three inverted U-shaped components. Two of these inverted U-shaped components, carrying the cover, are arranged so as to flank the third inverted U-shaped component, to which they are hinged, and which is vertically erected and secured by its ends to the sides of a boat. Each of the hinges disposed at each end of each of the inverted U-shaped components, carrying the cover, is formed by an axle arranged at this end of the component and capable or moving in a horizontal direction outwardly in relation to the vertically erected component and a bushing mounted on it. A spring-actuated stop locks the axle in its extreme positions when the cover is either fully unfolded, or when it is partially folded, that is when one of the inverted U-shaped components, carrying the cover, is placed on the other component.
