ABSTRACT:
An anchor having an elongated hollow body with a plurality of flukes pivoted to the lower end thereof. A stem inside the body has an upper end projecting through the upper end of the body connected to an anchor line. A connecting member couples a slideable plug held within the body to the stem for movement between a first position, where the plug holds the flukes in an extended operative position, and a second position, where the flukes are released from engagement with a surface. The connecting member, of which there are two embodiments, includes a spring tensioned as the stem is raised to an elevated position by a pull on the anchor line, the spring biasing the plug to its second position. A holding element locks the stem in its elevated position whereby a release of the pull on the anchor line will cause the spring to move the plug to its second position to release the anchor flukes. In one embodiment, the flukes may be moved to a storage position parallel to the body.
