And now, Bright Water has a place for it. Two places, in fact.
Here is the aft pooperplace.
Years ago, in the olden days, people went out in boats and didn’t discuss their poop. Now, poop is the thing boat builders must focus on, forever and ever. Poop management systems are required. This is ours:
Whatever was in the toilet is pumped up the pipe on the right and into the 20 gallon tank. Most of the time, it drains right out the bottom of the tank into the sea. Our tank is technically a vented loop.
If the cops are on to us, or we’re in a crowded harbor or a small cove, we close the drain valve and store our waste. Woot. When we’re in the clear, we open the drain valve and, umm, drain the tank.
If we decide we really want to be a part of the boating community, we can pull up to a pump-out station and empty the tank by suction through the small tube at the top. It’s connected to a rigid dip tube inside the tank that runs to the bottom of the tank.
If something horrible happens, and the tank fails to drain to the sea, the pump-out fitting is directly over the drain line and we can roto-rooter the whole thing from the deck. Hopefully not required. Ever. But we can.
Here is the lower plumbing:
The drain line is the big line in the center. The clear line supplies seawater to the flushing pump. The big line that runs across the bottom and up the right carries waste from the apparatus to the tank. The smaller line on the right is the sink drain.
The expensive-looking bronze valves connect the whole system to the ocean though the hull of the boat. They are called though-hulls. If they fail the boat sinks.
This is the forward pooperage. It’s a little smaller, but the same. Some people call these spaces “heads.”
I think that’s a little dated.
