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. Model LSI-104 pictured.
