Abstract: A portable basket is used to collect multiple weighted lines that extend between a buoy and a submerged crab pot. The basket is a cylindrical structure with flexible sidewalls that extend from a top edge to a bottom panel. Attached to the inside surface of the basket near the top edge are at least two ring connectors.

The weighted line's first connector is detached from the buoy and connected to a ring connector inside the basket. The winch is then activated to allow the weighted line to fall into the basket and get automatically stacked in a vertical coil configuration inside the basket. When the crab pot is lifted out of the water, the second connector is detached from the crab pot and attached to the second ring connector near the top edge. The process may be repeated to collect additional weighted lines.
