A boat anchor includes a short arcuate shank having transversely extending plow-type flukes at one end and transversely extending ears at the other end. A metal cable connects to the rear end where the plow flukes are positioned, and extends to a constraining guide located on the shank between the flukes and the ears. The cable then extends through a longitudinally non-constraining front guide on the shank end near the ears of the anchor. The cable partially wraps around the shank in its path be...

The invented sea anchor is made from two sheets of flexible material sewn together to create a generally frustum-shaped body. The body is collapsible and has a first end defining a first opening of a predetermined dimension and a second end defining a second opening of a predetermined dimension smaller than the predetermined dimension of the first opening. The anchor includes at least one fin mounted on, projecting outward from, and extending in an axial direction along the frustum-shaped body. ...

Ground anchors, in particular tent stakes (100), comprise one or more inherently flexible tines (110), a ground compression plate (160), and various tie points (420, etc.) for attaching a guy rope or the like to the top of anchor. The compression plate extends perpendicularly or at a large angle to the tine so that when the guy rope pulls on the anchor, the tine will tend to rotate about an underground fulcrum so that the compression plate will press against the ground and help the anchor resist...

An anchor has a fluke (3) having an underside (2) lying in one flat geometrical plane and comprising two fluke parts (5, 6) which each have a forwardly pointed tip (7, 8) on either side of the central plane (9) of symmetry which is perpendicular to the geometrical plane (2) of the underside. These two fluke parts (5, 6) form an integral unit at the central plane (9) and have their front edges (10, 11, 12, 13) in that geometrical plane (2) tapering towards the respective tips (7, 8) and from each...

An apparatus for stowing a "Danforth" type anchor and rode, comprising a frame with two vertical slots for receiving and supporting the anchor's stock ends, flukes, and shank. The frame is shaped such that the rode can also be supported and suspended above the deck. After a simple operation, the anchor and rode are stowed in a secure, upright, and compact manner. Provisions are also available for draining liquids from the interior of the apparatus, as well as, for protecting the deck from scratc...

A novel oar reversing arrangement including a handle portion, a paddle portion, an oar reversing device connecting said portions and including a pair of gears which are in a different plane from the movement of the portion. The pair of gears are essentially enclosed to prevent contact thereof by exterior objects. A novel oar lock assembly having an oar reversing arrangement, a channel member adapted to be snuggly and slidably received on a length of a gunwale of a boat, an attachment device rigi...

An improved anchor retrieving device adapted to be attached at an intermediate position of a main anchoring line. The device comprises a lock assembly comprising a gripper detachably mounted on an intermediate position of the main anchoring line, and a lock lever having a lower part swingingly supported by the lower portion of the gripper and an upper part releasably held by the gripper; a connection line for connecting the lock lever to one end of the shank opposite to the crown end of the anch...

A marine anchor is described which has a shank having a leading end for attachment to a cable and a general double-bladed ploughshare shaped fluke fixed to the shank with the blades disposed symmetrically about the median plane of the shank. The leading ends of the blades terminate in a single apex and the trailing ends of each blade diverges outwardly from said medial plane, each blade having a generally inwardly dished shape. The blades can be curved or consist of at least two flat angled surf...

An improvement in a mooring whip includes a locking cam adjacent the top of the mooring whip for securing a mooring line to the tip of the mooring whip and a release cord attached to the locking cam for selective release of the mooring line for slipping relative to the tip of the mooring whip, the mooring line and the release cord both being directed to a location adjacent the base of the mooring whip for operation remote from the tip of the mooring whip to either bias the boat away from the boa...
