@@fresnowfo Some may. But I think most shit in a plastic bag in a bucket and when they go ashore, they dispose of it in a dumpster or a port-a-potty. Same as people in vans and cars sleeping in Wal Mart parking lots.
Fort Lauderdale, FL. has the same problem, only their boats are bigger, like motor /sports boats and mostly are on the side. there is an old saying when it comes owning a boat.......1. happy when you own one, 2. Happier when you get rid of it.
