Abstract: A spooling assembly is mountable between a marine anchor and a rotatable winch spool to facilitate spiral winding of the anchor line of the spool. The spooling assembly has an independent power source, which moves a chain and a trolley connected to the chain along a path substantially parallel to a longitudinal axis of the spool. The trolley has rotating element, between which the anchor line is engaged. The anchor line is oriented in a direction substantially transverse to the longitudinal axis of the spool. When the trolley moves to and fro along set tracks the anchor line is guided to wind on the winch spool in a spiral manner. An emergency release air clutch allows freespooling of the anchor.
