If the holding tank discharge seacock is open, the tank drains by gravity overboard. If this valve is closed, waste
is stored in the holding tank. The rear holding tank release valve is located under the floor panel just outside
the door to the rear toilet.
The holding tank can be emptied by draining overboard at sea or by using a dockside pump-out connected to
the deck pump-out waste fitting.
