The Manta Ray Fiberglass blade has more surface area than Aqua-Bound’s other blade shapes, making it a great choice for big boats and moving water. This blade is made of exclusive Aqua-Bound abXII resin and is reinforced with fiberglass fibers. The Manta Ray Fiberglass paddle has a fiberglass shaft to help reduce fatigue and strain. This paddle provides plenty of strength and is lighter and warmer on the hands than an aluminum shaft. The Manta Ray Fiberglass has a snug, trouble-free 3-hole snap-button ferrule (0° to 60°, L and R feathering angles).
