Abstract
Abstract A floatable resilient body disposed for free movement about an anchor cable such that it floats on the water when the anchor is lowered below the water surface and which is shaped to automatically cooperate with the anchor when it is raised by engaging the anchor and rising with it thus shielding the anchor from other objects such as the boat and/or anchor holder to minimize noise and/or damage that might otherwise arise from anchor contacts with such other objects.
