The versatile Big B fender incorporates a Center Rope Tube that allows end-to-end line passage. It can be hung vertically or horizontally with a single line. Horizontal hanging is useful protection against pilings, awkward docking situations, and tidal change areas. Big B inflatable vinyl fenders feature seamless construction, with molded ribs to minimize roll. Big B's are made from the highest quality marinegrade vinyl with a high gloss finish. Available in four sizes to fit a full range of boat sizes.
