A sunshade which can be easily attached to and removed from the backstay of a sailboat. This sunshade is positioned so as not to interfere with the sail, and was designed to be attached behind the boom, so that it can be used under sail. This sunshade is constructed of two sheets shaped like isosceles triangles arranged with their bottom edges together to form a diamond shape, with a pair of spars fixed in place bisecting this diamond (perpendicular to the opening between the sheets). The sheets are not joined together, so that when the sunshade is attached to a boat, there is a space for the backstay to pass through. The spar combination is provided with multiple holes for adjustment when attached to the boat. This sunshade is suspended from the backstay with the spar combination topmost and the corners of the triangles at the bottom, being tied tightly to their respective sides of the boat.
