The double heavy-duty rubbing strake on all HB-AX models offers addition protection to the tubes from rocks, docks, and pilings. All HB-AX models also come with a vented bow locker large enough to accommodate a gas tank, and the ability to run a fuel line under the deck that enables you to free up deck space that is usually taken up by the fuel tank and fuel line. It also helps distribute weight more evenly by moving the gas tank forward. The flat deck with non-skid patches also offers better traction, safety, and comfort. This unique design also allows water to flow under the deck to keep your feet dry if any water gets into the boat.
