Abstract: A collapsible boat anchor comprising a fixed grapple and a movable grapple, the fixed grapple including a shaft having the movable grapple thereon. The shaft also includes a releasable lock adapted to unlock the movable grapple so that it lies parallel to the fixed grapple allowing storage of the anchor. The lock, in its locked position, locks the movable grapple in a fixed position whereby it extends transverse to the fixed grapple allowing the grapples to act as an anchor. The anchor also includes a tethering member selectively adapted to pull the anchor into an anchoring position or pull the anchor in a reverse direction to release the same.
