Abstract
An anchor with collapsible flukes is provided with a spring tensioned latching mechanism which normally prevents the flukes from moving from a latched position to a collapsed position. The latching mechanism is unlatched and the flukes collapsed by a releasing mechanism including a compression spring and a firing pin. Tension on an anchor line draws the firing pin against the compression spring and, upon a sudden release of the tension in the anchor line, the firing pin is driven against the latching mechanism to unlatch it and permit collapse of the flukes.
