Also known as "the head". We have two "heads" on Shibumi,
one aft in the Master Berth area and one forward for guests.
The pump on these things last for a long time as long as you lubicate the seal
and don't put anything you haven't eaten first in the bowl.
We had a guest who didn't follow the rules.
This is one reason Shibumi is well stocked with a supply of latex surgical gloves.
