I agree. In rough weather, I use a half gallon plastic milk container with a handle. I cut out the front 1/3 of the container, preserving the plastic handle and its supporting plastic base, then tied a line around the handle. You can use the container with the line attached to a cleat, then throw the whole thing over the side. The sea water will wash it out and you can haul it back in clean for the next time.
