Abstract: Boat fender covers for use with a fender of essentially any shape and size adapted to substantially cover a fender and being so configured to receive, and remain in position around, the fender. The cover, when in place and covering the fender, does not interfere with the proper operation of the fender. Apertures are provided in the cover to allow a rope to be used, as intended, in conjunction with the fender for tying to a boat. In addition, the shape of the cover allows for good accommodation of the fender. The structure and composition of the cover provide good durability, ease of use including simple removal for washing, and characteristics which reduce abrasion to the outer side surface of a boat, including gel coatings thereon.
