Abstract
A two piece shank structure releasably retains a single central shank tube detachable from the shanks. The shanks are affixed in position on the surface of two double edged flukes. The double edged flukes are attached to a main fluke shaft. The anchor line extends from the boat through the central shank tube where it attaches to a U-shaped bracket. The U-shaped bracket is attached centrally to the main fluke shaft by a rotatable collar. Both shanks are manufactured with an inherent spring biasing in the material, allowing them to be slightly separated for snap in connection of the central shank tube, and also maintains pressure against the central shank tube retaining it in position under normal use. Once the anchor has become snagged under a log or similar underwater snag it may be retrieved by pulling the anchor line at an angle relative to the shanks with the pull needing to be generally opposite in direction to which the anchor is suspected of sliding under a snag. With sufficient tension sometimes coupled with a jerk of the anchor line, the central shank tube will pop-out from between the two spring biased shanks allowing the anchor line to pivot with the U-shaped bracket. The anchor line through the middle of the shank tube and attaching to the rotatable U-shaped bracket allows the anchor to be pulled back out from underneath a snag in the opposite direction from which it was moving when snagged.
