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 vessel control system for a marine vessel propelled by at least one propulsion device includes a wireless lanyard system including at least one fob worn by an individual on the marine vessel and a helm transceiver at a helm area of the marine vessel configured to receive radio signals from the at least one fob. A controller is configured to detect, based on communications between each of the at least one fob and the helm transceiver, that each of the at least one fob is present on the marine vessel. A missing fob is detected if at least one of the fobs is no longer detected at the helm transceiver, and then a man overboard event is generated. The vessel control system is configured to automatically activate one or more search assistance functions based on the man overboard event.

A floating object attachment system for attaching one end of a rope or cable attached at its opposite end to a submerged anchor. The attachment system includes a rigid support pole attached to a mounting plate attached to the bottom surface of a floating object. Attached to the support pole is a swivel arm adapted to rotate freely 360 degrees around the support pole. A plurality of radially aligned gussets hold the support arm perpendicular to the mounting plate. The swivel arm includes a horizontal flange with a center bore that receives the support pole and a lateral, downward extending diagonal arm with a grommet hole that connects to the rope or cable. The support pole includes a lower stop surface and an upper stop surface on the support pole. Disposed around the support pole and between the horizontal flange and the upper and lower stop surfaces are nylon washers.

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.

A decoy tethering device for deploying and retrieving a decoy assembly includes a housing. A line is selectively extensible from and retractable into the housing. A fastener is selectively couplable to the line. A coupler that is coupled to the housing is configured to couple to a keel of a decoy. A connector that is coupled to a second end of the line is configured to couple to a weight. The fastener is positioned to decouple from the line to both extend and retract the line from the housing, and to couple to the line to retain the line in an extended configuration. The coupler is configured to couple the housing to the keel of the decoy. The connector is configured to couple to the weight to position the weight to retain the decoy in place on a surface of a body of water in which the weight is positioned.

An anchoring device may be arranged above or below a body of water and may secure or anchor watercraft to at least one vertical object and/or horizontally-positioned object. The anchoring device may provide a clamping mechanism that may secure the anchoring device to the at least one vertical object and/or horizontally-positioned object. The anchoring device may be integrated or fixed to watercraft, such as at a seat pedestal. The anchoring device also may be used without being integrated or fixed to watercraft.

A marine vessel (10) includes a hull (11), an electric propulsion part (15) configured to propel the hull (11), an anchor part (20) that is connected to a chain cable (21) pulled out from the hull (11) and is submerged in water, a power generating part (63) submerged in water together with the anchor part (20), and a battery case (30) configured to accommodate a detachable portable battery (35) that is an electric power source of the electric propulsion part (15), wherein the battery case (30) is integrated with the anchor part (20) and connected to the power generating part (63).
