SPAR TRACK CLEANING AND MAINTENANCE DEVICE ABSTRACT The spar track cleaning and maintenance device ( 10) comprises: a compressible, working surface for cleaning, lubricating and maintenance of a longitudinally extending, irregularly-shaped, spherical opening defined by a spar track; at least a first compressible, resiliently flexible, cordage member (30) for inserting into the spar track (50) opening and for slidably engaging an internalsurface of the track opening; and a control means (38) for adjustably shaping the working surface and the first cordage member (30) upon being inserted within thespar track (50) opening. The control means (38) adjustably shapes the working surface and the first cordage member (30) which is integrally formed with the working surface to allow the working surface and the first cordage member (30) to compress and substantially conform to the irregular spherical shape of the internal track surface and be in slidable engagement therewith. The compressed working surface and the first cordage member (30) upon being slidably moved within the track opening reduces friction at the internal track surface and enhances the sliding of the mating slides and boltropes when under loadings from the sail.
