A foldable anchor storable on watercraft with limited storage and deck space and which secures watercraft in place in sandy and soft bottom boating areas and is releasable from underwater objects. The foldable anchor includes a forward anchor body with an internal weighted ballast on an anchor body and a two-part shank pivotably attached to a top end of the anchor body which allows the shank to pivot from an elevated position to a lowered position relative the anchor body. The shank has a rear portion and a front portion pivotably disposed thereon and foldable against the rear portion. Stabilizer wings between the front and rear portions assist the anchor body to roll into a correct upright position. Locking pins secure each of the rear and front portions together and the rear portion and anchor body together at selected angles. D-rings and breakable zip ties secure the shank to an anchor rope.

The present invention relates to a hybrid dynamically installed anchor with a folding shank and a control method to keep the verticality of the hybrid anchor during free fall in the seawater, which can be applied to the field of offshore engineering. The hybrid anchor comprises a folding-shank plate anchor, a ballast shaft, an extension rod, a plurality of rear fins, and a recovery hole from the front to the tail. The folding shank is not only useful in reducing the water and soil resistance during installation, but also beneficial in improving the directional stability of the hybrid anchor during free fall in the seawater. The re-used shaft can significantly increase the penetration depth of the folding-shank plate anchor and reduce the installation cost at the same time. The control method keeping the verticality of the hybrid anchor can improve the success rate during anchor installation.

A common experience for boat owners is to lose anchors, particularly when anchored next to structure, wrecks, sunken debris, tree roots, rocks or other obstacles that are likely to become firmly engaged, holding the flukes of an anchor. Attempts to release the anchor by maneuvering the boat or by the manipulation of the anchor line often prove futile and succeed only in increasing the entanglement of the anchor. Ultimately it may lead to anchor loss or even loss of life of those on board the boat. This fluke style anchor mechanism design was invented by research and development through which the inventor created the Radial Arm Double Shank Split Crown Self-Releasing Mechanism Anchor providing a superior, safer, practical and economical solution to overcome the aforementioned problems of past art devices referenced herein or exhibited within this document shown in exhibits; Description of the Prior Art or Patent Citations and Searches.

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.

Provided is an anchor for a ship that may facilitate retrieval of the anchor as a folding operation of the anchor is smoothly performed by improving a design of a contact portion such that a mechanical contact resistance of components that perform a folding operation of the anchor is minimized. Consequently, the anchor may be easily retrieved without cutting the wire or the iron chain, that is, without loss of the anchor in a situation in which the anchor arm is caught by an underwater structure not to be pulled out when the ship leaves a harbor after the mooring.

An apparatus includes an elongated, hollow member; a cap; and a pair of arms. The elongated, hollow member has a first closed end and a second open end, wherein the second open end includes a plurality of slots therein. The cap is configured for detachable attachment to the second open end. The pair of arms is configured to fit into the elongated, hollow member in a first configuration. The pair of arms is configured for insertion into the plurality of slots in a second configuration, wherein one of the pair of arms is oriented substantially orthogonally to the other of the pair of arms. A method of using an anchor includes inserting a pair of arms into the elongated, hollow member; and closing the second open end with a cap configured for detachable attachment to the second open end.
