I have a 36-foot sail with a relatively small
holding tank and although I have direct discharge when at sea, there is no way to
pump the tank when out at sea. Been thinking about prota potties. Seems like an easy solution with dumping over-board when at sea. However, when at dock, the prospect of hauling a full sewage tank to the on-shore toilet does not seem all that attractive. Anybody with experience with this?
