I purchased 2 of the SandShark Anchors 4 years ago and can attest to their longevity and holding power. We have had as many as 3 boats tied off to our anchor in 35 MPH winds when everyone else anchor was dragging. If you're anchoring in less than 6' of water, with a sandy bottom there is nothing that compares to the holding power of these anchors. One of the best under rated benefit is that it collapses into its own carrying case and can be stored just about anywhere. That way you can still carry your regular anchor in the anchor locker for deeper anchorages.
