  • (a) a disc having a disc axial axis perpendicular to a face of said disc, the disc axial axis being positioned in a central portion of said disc, said disc also includes an aperture through said disc in the disc axial axis being positioned such that said aperture uses the disc axial axis as a centerline, said aperture is sized and configured as a passage for the marine mooring line, said disc also includes a radial slot through said disc in the disc axial axis, said radial slot extending from said aperture to a periphery of said disc, said slot having a radial axis parallel to said slot;

    (b) a closure sized and adapted to insert into said slot in a closure axis approximately parallel to the disc axial axis, said closure is in a closed state when inserted into said slot and is substantially flush with said disc face, said closure also sized and adapted to extract from said slot in the closure axis approximately parallel to the disc axial axis, said closure is in an open state when extracted from said slot to allow the marine mooring line to pass through said slot from said periphery to said aperture; and

    (c) means for urging said closure from the open state to the closed state.
