This float rope mat is a muted yellow and light blue and measures 24" X 36". Float-rope is used by lobstermen to tether multiple traps together on the ocean floor. The problem with float-rope is that it can entangle whales, which sometimes leads to their injury or death. Now, Maine lobstermen are required to replace float-rope with sink-rope. Finally, without an appropriate recycling outlet, hundreds of thousands of pounds of this turned-in float-rope could end up in Maine landfills.
