Abstract
A pulley system for tying a boat to an anchor comprising a block and tackle assembly and a jammer. The block and tackle assembly has a plurality of pulleys arranged on a first bracket and a second bracket, and a first rope strung sequentially through each of the pulleys, ending with a last pulley. The jammer is coupled to the second bracket and has a channel and a jammer exit at the end of the channel. The last pulley, the channel, and the jammer exit are configured to create a tortuous path for the rope through the second bracket. The channel may be misaligned with the last pulley. A swivel and a rope clip may be coupled to the block and tackle assembly. The swivel is configured to rotate at least 360 in either direction. The rope clip is configured to allow for quick tightening of the pulley system.
