Ultra-light hulls are stiff and incredibly light. They are ideal for speed and distance paddling and for all people or conditions that demand the lightest gear. In our Ultra-light construction, a structural foam core and ribs are laminated into the hull and sides. We also add extra fabric layers to strengthen specific targeted areas. Aluminum plates are strategically laminated into the hull. Seats, footbraces, and all hardware is then riveted into these plates. This gives a very secure connection and eliminates rivet heads on the exterior. Kevlar®, the fiber used for aerospace, body armor and bulletproof vests, is amazingly light and strong. We've used it for more than 30 years to construct extremely light and tough canoes. Wenonah Canoe is the worlds largest maker of canoes using Kevlar®.
