This anchor has been rigorously tested and proven on some of the toughest waterways in the country— the Mississippi, Missouri, and Ohio Rivers. Engineered with a unique design that allows it to catch securely before it snags, it provides unparalleled holding power on sandy, muddy, or rocky river bottoms. The grapple hook shape makes it ideal for maneuvering up to rock dikes and gripping onto sandbars with ease.
