I know its a shitty topic but, what do you do when sailing around the islands with Gray/Black water. Do you keep two tanks and keep the poop pumper separate. Is all gray water dumped/pumped out below the water line. And finally, who uses sea water for the poop pumper and pumps it directly out with the gray water ?
Most boats that I am aware of have no gray water tanks, only holding tanks for the black water for pump out or discharge offshore. The gray water simply goes overboard through a thru-hull, usually below the waterline. George
