This invention relates to a multi-purpose, eco-safe bag for your gear which can be used interchangeably as a sand anchor to keep your stand up paddle board, kayak, or raft anchored in position while you are snorkeling, fishing, doing yoga, or just relaxing and hanging out in the water. Fill The SUPSAC with beach sand and attach to a leash or any length of rope to secure. The SUPSAC may also be used to secure beach umbrellas or canopies. This product is easily transportable at approximately 14 inches by 11 inches, light weight and multi-purpose. This product has no sharp blade type pieces which could harm the ocean environment, sea life, or another person. This product will not get hooked onto seagrass, corals or stuck on rocks as a claw type anchor would therefore making it an eco-safe product. When finished, simply empty the sand back into the water, returning it to its natural environment, re-pack your gear inside the canvas bag and continue on your paddle adventures.

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.

A system for controlling a marine vessel comprises an input device for inputting an operator command, a sensor which senses and signals an engine function variable or a vessel dynamic variable, and a first structural element and a second structural element. The first structural element and the second structural element each control speed or direction of motion of the marine vessel, and the first structural element and the second structural element each affect the marine vessel dynamic variable. There is a controller which receives the operator command and the engine function variable or the vessel dynamic variable. The controller moves the first structural element and the second structural element based on the engine function variable or the vessel dynamic variable, after receiving the single operator command.

A decoy control apparatus for organizing and displaying a spread of buoyant decoys in a free-surface marine environment, the decoy control apparatus including a pliant, water permeable sheet for subsurface deployment with a plurality of buoyant decoys attached thereto for surface display of the plurality of buoyant decoys grouped in a predetermined spread, a tethering assembly mounted to the sheet for removable attachment of a plurality of buoyant decoys thereto and a ballast attachment arrangement fixed to at least one end edge of the sheet for attachment of at least one ballast weight thereto to downwardly bias the sheet against the upward bias of the buoyant decoys, thereby stabilizing the sheet in a subsurface disposition intermediate the surface-borne buoyant decoys and the at least one ballast weight.

An anchor system for watercraft includes: a hub including a receiving contour; a skirt removably securable to the hub along a receiving contour of the hub, wherein: the skirt at least partially surrounds an inner recess and includes a gap such that such that the skirt is not circumferentially continuous; and the skirt is configurable in an open position and a closed position, wherein when the skirt is in the open position the gap is wider than when the skirt is in the closed position. The inner recess of the skirt has a radius that is larger than a complementary radius of the receiving contour of the hub when the skirt is in the open position. When in the closed position, the radiuses are substantially the same, such that the skirt is secured to the hub when the skirt is in the closed position.

A modular anchor comprising: a top cross, wherein the top cross comprises a central tubular pile and one or more arm attachment tubulars and one or more cross arms connected to the one or more arm attachment tubulars and associated methods and systems.

A system for anchoring a floating object (e.g., watercraft) to the terrain forming of a body of water (e.g., bottom of lake). More particularly, the system provides an anchoring system that allows a rigid support structure to be configured between the anchor point and the watercraft, thereby fixing the watercraft in a constant position.
