AB’s commitment to innovation remains at the forefront in the development and design of “Ultra” Light Aluminum Hull RIBs. Using the same high quality and Orca (CSM) five layer coated fabric tubes, we offer a less expensive version of our already popular AL series. The ULs are the lightest and more spacious light series boats in the market. While the unpainted hull provides for minimum maintenance, the rubber non-skid floor adds comfort and safety. The UL series are the preferred choice among sail boaters around the world.
