Our Thwart Bag provides much-needed storage space on an inflatable boat. It attaches with a hook-and-loop enclosure and will fit most inflatable thwarts. The web straps that secure the bag to the thwart can be used as handles or shoulder straps to carry the bag when you leave the boat. Vinyl material will not mildew and is waterproof. The bag is approximately 20" wide, 12" tall and 4" deep.
