Re: [Amel Yacht Owners] Holding Tanks in Amel Santorin

georges pellegrini <dji314@...>

When Amel instals the tank, the cover panel is cut in half vertically
and the rear portion is fitted with screws (7 I believe). The tank is
only in the rear half of the locker, above the shelf. To get access to
the tank you just have to remove the little cabinet and the wood towels
bars, and then the panel comes easily. The tank is fiberglassed to the
hull. It is only about 10 gallons or so.
The vent is done through the cap on the deck and through the exit hole
when the valve is open. Actually, it is only a small hole in the cap,
but it seems to work since I visited it last summer, and it is fairly
clean (if I can say that), with no bacteria growth. Very easy to rinse
Actually I had a pump go bad, and it is true that when you open, all
what is in the big white pipe dumps into the shower tank. But
fortunately, you have the shower...

The structural integrity is a valid point.   When AMEL retro fit their
tank to a Santorin they only use the after top section of the heads
lockers (for’d), and do not remove the centre partition as I have done
to fit a larger tank.   My question to anyone who has had a reto
fitted tank in a Santorin is “does AMEL fibreglass the face panel (the
for and aft panel that covers the lockers) back in place?”   If they
do I don’t see how you can replace all the pipework.   You can replace
the outlet pipe easily enough but I don’t see how you get to the inlet
pipe and, if ever necessary, the pump out pipe and if they don’t then
they must feel that the strength generated is not absolutely necessary
– can anybody explain?
  A factor that worries me if the apparent lack of a ventilation pipe
to the tank.   All my reading, and advice from manufacturers states
that you need air circulation in the tank to keep bacteria down and
reduce smell.   Does AMEL really not have a air vent pipe?
  From experience I do like the simplicity of the straight through
system where the heads can flush straight to sea and can be held in
the holding tank in port by use of one valve.  Only the heads pump to
go wrong!
  I’m a bit puzzled by the use of PVC pipe.   We spend a great deal
of money fitting odour proof piping so why doesn’t the odour penetrate
the PVC, and if it doesn’t why do the builder fit expensive pipe?

  A prior owner of our boat, "Sangaris" (Hull#68-1992), did an
installation similar to Robin's except the full wall panel was
removed so that after the tank was installed on the middle shelf and
the full original panel put back in place it kept the original
appearance.  You can't get to the tank without some dissembly, but
not a problem so far.
  Unfortunately, you loose storage space and destroy the monocoque
structure Amel intended by having the full panel bonded in place. I
think a better solution would be a Raritan Saniflush/holding tank
combo installed under the towel rack next to the toilet, with some
finish paneling over it for appearance sake. It would give you easy
maintenance access and avoid the downside of cutting out the panel.
Plus that space is only handy for hanging towels - you could stil
have a foot or so above the unit. You could also nudge it a bit under
the sink.
  By the way, I replaced all the hose with PVC piping and flexible
rubber couplings to the thruhull, toilet, tank & Y-valve. It works
great, is easier to work with than hose and NEVER smells.  I run
muriatic acid through it periodically to disolve salt buildup -
(which works with hose, too.)
Good luck,
