A main sump well is located under the floor of each hull.
It is drained by:
- A manual bilge pump in cockpit.
- A manually activated electric bilge pump (Electrical panel).
- An electric pump to automatic sump located in the sump.
The fore compartments and the engine bilges are watertight. A hose
equipped with a valve enables water that enters accidentally to run
into the sump.
Under normal conditions these remain closed.

Waste water from the heads is drained off by a thru-hull fitting with
ball valve (the valve is closed when the valve handle is perpendicu-
lar to the hose, the valve is open when the valve handle is in line
with the hose).
