When you consider the abuse decks take from scrapes, the sun, salt-water and even oil and gasoline, it makes sense to have the toughest material available to protect them ? and that is Hypalon. So our remarkable AirFirm floors are not only incredibly lightweight and rigid, they are also the most durable you will find. Thousands of polyester threads make our air floors super firm. The additional support of an air keel increases floor rigidity and along with a new fiberglass transom enhances overall performance. With large tube diameters, LSI tenders carry heavy loads despite their light weight. There are six different LSI model sizes to choose from. No other air floor tenders offer more convenience, more quality or more choices.LSI Standard Features Include: Hypalon/Neoprene reinforced fabric; air keel & fiberglass transom (all models except LSI-77); Hypalon drop stitch AirFirmtm Floors; full length tear drop rubbing strake; bow carry handle; internal bow D-ring; fold down locking oar system; two-piece break down aluminum oars & oar holders; towing bridle D-rings; life lines; removable wood rowing seat; protective motor clamp; self-bailer valve; large high pressure foot pump with pressure gauge; carry bag; maintenance kit; and floor protection pad for gas tank.17-inch tube.
