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.

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.

A variable weight boat anchor having an added weight storage capacity for submerged unloading of added weight is presented. Remote signal from a boat triggers the release of added matter in the anchor for a lighter pulling.

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 has a fluke, a shank that is connected to the fluke, a coupling to attach the fluke to an anchor line or anchor chain, and an angle adjustment provision to adjust the angle between the shank and the fluke, wherein the angle adjustment provision is a hinge between the fluke and the shank, a first positioning member connected to the shank that is provided with a series of first positioning holes at a first intermediate distance and a second positioning member connected to the fluke that is provided with a series of second positioning holes at a second intermediate distance and spaced apart from the hinge axis, and a positioning pin that is inserted in one of the aligned first and second positioning holes, wherein the second intermediate distance differs from the first intermediate distance.

Disclosed is an anchor having a fluke, a shank that is connected to the fluke, and a coupling to attach the fluke to an anchor line or anchor chain, wherein the shank has two shank legs each having a straight shank plate with an outer surface that extend on the opposite sides of the plane of symmetry of the anchor and that diverge from the coupling towards the fluke, wherein the fluke has two straight penetration plates with a top surface on the opposite sides of the plane of symmetry of the anchor, wherein the orientation of the outer surfaces with respect to the top surfaces is specified by three angles under narrow ranges to provide excellent penetration properties and an excellent holding capacity.
