I don't need one, but suppose one is cruising down the ICW on the trip from New England to the Keys just what happens to the "composted Material"? Do marinas accept it, does it go into a dumpster ,spread over the lawn, is it dumped over the side. If one anchors out just haul it ashore and dump it? What happens to the "new deposits" at the end of a cruise?
I am sure it is great fertilizer, but doubt many waterfront land owners will welcome it being spread in their flower beds.
