A simple, easily affordable and portable, yet rugged and reliable, collapsible anchor is disclosed for use with small water craft, particularly those susceptible to damage by sharp edges or protuberances of a conventional non-collapsible anchor stower aboard.

The force trips a release mechanism which allows a pair of flukes to rotate in an "A"-shaped spring yoke in which they are held, and unsnag the anchor. The flukes are nonrotatably disposed on a fluke shaft which is journalled in the lower terminal portions of the yoke's two spring arms. The upper terminal portions (apex) of the yoke are held together by a fulcrum pivot (shoulder bolt) means. The release mechanism comprises, a spreader bar having a clevis in its upper terminal portion and a release pin in its lower terminal portion, the release pin being biased against the spring arms; and, a line lever having a through-bore in its lower terminal portion and a cam end, the anchor line being attached to the other end. The line lever is pivotable about the fulcrum pivot member, and held in the clevis so that the …
