ABSTRACT:
A boat anchor which includes a hollow shank having a line attachment eye at one end and protruding fins at the other end. Anchor flukes are pivoted to the fins for movement between three positions, namely: an operative position extending generally laterally away from the shank, an anchor-releasing position in which the anchor flukes extend longitudinally of the shank and away from the line attachment eye, and a storage position in which the anchor flukes extend alongside the shank towards the eye; shear pins carried by the fins are broken by the anchor flukes under the application of a predetermined load to permit pivotal movement of the anchor flukes into their anchor-releasing position. A spring-loaded plunger resiliently maintains the anchor flukes in either one of their storage and operative positions. A stop bolt can be adjusted to block the plunger into a position in which it positively locks the flukes in their operative position, whereby anchor-releasing is no longer possible.
