With its beefy blade, the Manta Ray Carbon is a great choice for high-angle paddlers, those looking for more power, bigger boats, and moving water. This power is balanced out with an ovalized, 100% carbon composite shaft, which means less fatigue and joint strain. The Manta Ray Carbon has two ferrule options. In addition to a snug 3-hole snap-button ferrule (0° to 60°, L and R feathering angles), this paddle also offers the Posi-Lok® ferrule system which clicks into position firmly and securely. The Posi-Lok® features strong, corrosion-free composite construction, convenient dual-button release, and infinite feathering angles.
