A watercraft storage apparatus for protecting the hull of a watercraft both above and below the waterline without the need to lift or raise the watercraft out of a body of water. Inflatable side portion 11 protects the watercraft's hull above the waterline. A water-impervious lower sheet section 12 protects the watercraft's hull below the waterline. An aft section provides a drive-in ramp section 13 or a drop-down gate section 19 to provide ingress and egress of the watercraft from the storage apparatus.
