Trailers can serve double duty - both moving the boat from here to there and storing your boat in a safe spot. Defender Marine offers a line of bunk-type trailers that haul boats up to 21 feet LOA and 3300 pounds. Trailer bunks - or rails - diffuse the weight load and offer secure, long-term storage. Inflatables, soft and rigid, are light enough to slide onto the bunks at the ramp. These single-axle trailers are easy to maneuver and boast a powder-coated surface over galvanized steel for a long life. All boat trailers are offered with a manufacturer's warranty.
