Yamaha s new 3-rider towable has fins on top, to help riders stay on the tube and out of the water. The 6 deluxe nylon-wrapped handles with neoprene knuckle guards provide a sure and comfortable grip. It measures 72 x 62 (deflated) and is equipped with a heavy-duty Kwik-Connect for easy and secure hook-ups. The tough 30-gauge virgin PVC bladder is fully covered with an 840D double-stitched nylon cover for years of service. A Boston valve provides the ultimate in inflation and deflation convenience.
