ABSTRACT:
A dynamic anchor composed of two laterally positioned anchor flukes for facile penetration into the bottom structure of a water course, and a retractor to withdraw the flukes from the bottom. The retractor is mounted for relative reciprocal movement along the longitudinal axis of between the flukes. Two anchor cables are employed. The first cable is connected directly to the fluke plate and is used to anchor the craft. By pulling the first cable, the fluke plate is pulled forward to dig in and hold the craft. The second cable is reaved around a pivot carried by the retractor and is secured to the fluke plate. Thus when the second cable is pulled in, there is created a force to pull the retractor and fluke plate in opposite directions in order to cause the flukes to be removed from the water course bottom.
