F.4 SCUPPERS
Your boat has a series of scuppers to drain
away water from rain or from deck-washing
operations.
The only important precaution to be taken
with these scuppers is to ensure that they are
not obstructed with solid wastes, rags, paper
or anything else that might block them. In
particular, you should check periodically
that the drainage holes of the chain locker
at the bows are free from mud and weed.
The cockpit drainage discharge valves must
normally be left open.
WHEN SETTING THE POSITION OF THE
VALVE CONTROLLING THE DISCHARGE

REGULATIONS OF THE COUNTRY IN
WHOSE WATERS YOU ARE SAILING.
F.3 BLACKWATER – TOILETS
Wastes from toilets are called “blackwater”.
Toilets are flushed with seawater supplied by
seawater intake valves for each toilet.
If electric toilets are installed on board,
they each need a specific electric pump for
seawater flushing. This pump is located
inside the adjacent washbasin cabinet.
Wastes from the forward toilet (optional) are
discharged directly overboard. Wastes from
the aft toilet are sent to a specific holding
tank. This tank can then be emptied by gravity,
by opening the through-hull discharge inside
the cabinet under the washbasin.
The aft toilet blackwater tank can also be
emptied by the suction disposal systems avai-
lable in many marinas, using a specific hose
connected to the discharge connector on the
starboard side of the deck.
You should check that the blackwater tanks
have been emptied before you reach your
mooring.
Do not leave wastes in the tanks for
several days without emptying them. This
will prevent the accumulation of heavier
wastes on the bottom of the tanks. To avoid
encrustation and blockages, all pipes and
tanks of the blackwater discharge system
should be regularly flushed with abundant
water.
The capacity of the tanks will give you an
appreciable cruising range without having to
empty them, as long as excessive amounts of
water are not used for flushing.
In this case, it is essential to limit the use of
toilet paper, and if possible, this should be
disposed of separately in a paper bag. This
will reduce the risk of blockages.
