Abstract: An anchor for small watercraft. It is extremely lightweight, and can be stored in a very small space. The anchor consists of a pear-shaped fabric ballast container. This container is made up of a number of matching side panels and a circular bottom disc. A set of four metal or composition flukes attached to the ballast container near the bottom and at the widest part of the container. Each fluke is about 9-11? long, ¾? wide, ½? thick, with an angled tip at one or both ends. The flukes are thus deployed by weighting the bag with material like gravel or sand, which forces the flukes to protrude sharp angle from the ballast bag. When filled with material, the anchor approximates the function of traditional fluke or bell anchors. The anchor can be turned inside out for self-storage, requiring no additional storage container.

Abstract: An anchor incorporates a release mechanism that is releasably assembled to a shank. An anchor chain is affixed to a crown section of the anchor.

A pair of release interface notches is formed within the proximal end of the release mechanism; the slots are placed on opposing sides of the release mechanism. A pair of release interface fasteners is disposed along a distal end of the shank. The release mechanism is held in a mooring configuration by engaging the release interface notches and the release interface fasteners. The release mechanism maintains the chain in a mooring configuration until the release mechanism is rotated perpendicular to the shank, wherein the release interface notches disengage from the release interface fasteners changing a tensile force from an anchor engaging direction to a releasing direction.

One end of the shank is attached to the fluke and the float is attached to a rearward portion of the shank, with the float's center of buoyancy spaced away from the connection to the fluke. Upon being put in the water, the anchor quickly assumes a generally upright orientation, i.e., shank up and fluke tip down.

Abstract: A modular anchor with a stress sensitive shank that permits its easy retrieval from the floor onto which the anchor became stuck. This retrieval is accomplished by merely pulling the anchor cable, the integrity of the cable being preserved as a consequence of the yielding of a shear pin that is part of the modular anchor.

The modular anchor may be disassembled to be carried in a bag with other elements useful for fastening a boat to shore. The anchor preferably has a fluke in the form of a plow or plowshare fluke.

Abstract: A marine anchor for recreational boats comprising a rotating hub, with a plurality of flukes extending outward, and a substantially right-angle shaped bail member including five bail positions for receiving a slidable shackle of an anchor chain. The first bail to shakle position is the anchored position. The second bail to shackle position allows for a conventional retrieval of the anchor from above the location of the set anchor. An alternate retrieval can result in a third bail to shackle position from an anchored boat position further away from the set anchor. In the second and third positions the flukes are free to rotate enabling the marine anchor to be retrieved. A fourth position of the bail to shackle position is pulling the anchor chain and shackle from the opposite end of the anchor. A fifth position of the bail is a resting position on the bed of the sea floor by releasing the tension of the anchor chain such as during a slack tide to minimize entanglement with other loose anchors or debris.

Abstract: A marine anchor designed so that it positions itself automatically and penetrates instantly into all kinds of sea beds with maximum holding power. The geometry and ballasting of the anchor ensure automatic positioning of the anchor. The off-center position of the ballast counter-balancing the weight of the shank places the center of gravity of the anchor as close as possible to the anchor tip, so that the tip can bear practically half the total weight of the anchor, the pressure exerted by the top on the sea bed is increased, and its penetration into the sea bed is promoted. The sharp corners between the two sides of the tip aids penetration into all kind of sea beds, including sea beds covered with thick seaweed, and the concave surface of the fluke provides maximum holding power. Said anchor is suitable for mooring yachts and fishing boats, as well as for marine industrial use.
