A self-retrievable anchor with a shovel, lever, and manifold contains no welded parts eliminating weld failure due to tensional and bending forces during anchor retrieval. The anchor has interchangeable parts. The manifold attaches the shovel to lever, and contains at least an internal breakable fuse. A specific dimensioned fuse to anchor size is used. The fuse is not universal. When a tensional force is applied above fuse shear strength capacity, and below breaking strength of the rope, the fuse breaks rotating the shovel 180° about a pivot hinge pin. The anchor is released when stuck at sea bottom without any loss. The anchor's interchangeable parts makes it capable to change shovel shapes suitable to different sea bottom conditions. A stop bar on the shovel portion may be included. The lever may also detach during retrieval by a breakable pivot hinge pin or fuse pin alone, and shovel/manifold later replaced.

An anchor rescue system includes an improved slider assembly 200 and retriever assembly 300 allowing for secure attachment as the retriever assembly is lowered upon an anchor line to attach to the slider assembly. Once attached, the retriever assembly pulls upon the slider assembly with the slider assembly attached to a tether chain 210 with the tether chain attached to a lower portion of the anchor, such as crown, causing the anchor to move upwardly in a relative horizontal position. The system frees trapped anchors without need for floatation devices.

The anchor-retrieving system comprises a recovery harness and a lap link. The recovery harness may couple to an anchor via the lap link such that if the anchor becomes fouled the lap link may fail and a trip line of the recovery harness may be operable to recover the anchor by pulling the anchor from a crown of the anchor. The recovery harness may comprise three loops. A first loop may couple to the head of the anchor via the lap link. A second loop, adjacent to the first loop, may couple to an anchor line via rode hardware. The third loop, separated from the others via a trip line that is longer than the shank of the anchor may couple to an aperture in the crown of the anchor.

An anchor for a watercraft comprising a shank and at least one prong adapted for attachment to the shank, wherein the anchor for a watercraft also comprises at least one weakened connection configured to release the at least one prong from the shank when a load on the at least one prong exceeds a predetermined threshold.

An anchor (1) comprises a fluke (2) and a shank (3) pivotally connected to one another. The shank (3) is pivotable between an anchor deployment configuration and an anchor retrieval configuration, and a fastener 36 is provided to engage with the shank 3 to retain the shank (3) in the anchor retrieval configuration.
