Thank you so much for responding, I was beginning to wonder if anyone out there. I may keep the houseboat on the same lake I live on, but may have to rent a slip from a home owner. I'm trying to design things to fit all circumstances and if Coast Guard does an inspection has to be passable. Gray-water area/zone or not, it has to be passable for the area. I have no black-water tank (will use good quality port-potty.) I want to avoid that whole thing right off from the start. Next I will put together the actual plumbing route--I find it a true wonder how I can Email someone all the way in New Zealand, what is it like there? What are the people like? Are you stationed there permanently or sailing through?
Thank you again for responding. Roger fromMount Dora, FL (on Lake Dora.)
