No, you should have no marine toilet whatsoever in order to protect the
environment. You should just hold it until you get back, or better yet,
don't boat in "our swimming pool" as you put it.

I am building a cat and I was planning to install a Lavac head (manual, no
power requirements...) with tank.
But msd+tank appears interesting...
It is expensive and needs space, but in case of failure of msd the tank
can
save the day.

I believe Paolo's concerns are valid and his queries sincere. While it
may be counter-productive to be obsessive on these topics, I believe
that it is helpful that we as sailors consider clearly our options in
regards to waste disposal and power management.

Part of the attraction to sailing as a lifestyle is that it is
relatively easy on the environment, as opposed to, say, driving a
Hummer to Mexico. The continuing interest in marine heads, composting,
windvane and wind turbines, solar panels, electric and/or fuel cell
diesel replacements, and so on reflects a concern not only for energy
"independence" to extend cruising, but also a desire to "sail lightly
upon the earth (or sea, I suppose)".

If forums like this can educate or elaborate on the options available,
all to the good. Sarcasm, I find, is less helpful, unless it is
directed at trolls.

Sailing lightly is good both for the sailor and the planet. As I
progress with my own boat building project, much of my effort is in
exploring and exploiting 'free energy' sources for all the basic needs
and finding ways to do so without busting the budget. Many resources
exist out there and its not a new concept. I like the idea that my
voyaging can be less stressful on the planet than driving my car to
the mall.

Hi, Y'all,

Truncating this to a question or two:

"Peggie Hall" wrote in message
...
Any manual marine toilet that's working anywhere near factory specs can
move bowl contents at least 6' in the dry mode...so if you learn how to
flush your toilet correctly, there shouldn't be any water or waste in
the line between the toilet and top of the loop to run back down into
the bowl.

This has me very curious. You're saying that enough
speed/pressure/whatever-moves-it is developed, in an anti-siphon environment
(the vented loop), that I can clear a 1.5" line for what is (in the new
installation) about 3.5-4 feet (to the top of the loop) by dry flushing?

I buy that I might be able to flush solids, with water, that far, if I'm
aggressive enough with my volume (and the Raritans we have probably put in a
cup per stroke or so), but I don't see how that pipe can empty, dry pump or
not. I'd have to think the surface tension of the water would not be
sufficient to prevent the water running past the bubble at the edges, as you
recharge between strokes. I'd be thrilled to think I could really empty it,
as that - with a straight discharge - would go a long way to keep odor down
(should be only sea water to make odor, that way). Help me out with my
physics, here?


On the subject of joints, I'm of distinctly curious mind. While my
current
home isn't this way, my prior home had hundreds of feet of PVC pipe run,
with all the necessary ells, Ts and other fittings, all successfully
carrying high pressure hot and cold water.... Am I missing something?

What you're missing is: houses stay put...they don't get tossed around
by wind and wave. Boats do.

Well, yes, of course. But if I secure a large pipe, in a short run, under
next to no pressure, it's not going to move. In the house example, you
could see the distortion of the hot water pipe from expansion vs resting
state as hot water entered, and see it jump as the water was shut off and
turned on - but it all stayed together. In the boat, we'll use hose as
movement absorbers.

Not trying to be argumentative - just understand why I shouldn't be doing as
SeaLand recommends...

By the way, I promoted your book to several people complaining of stinky
heads, and saw many of them being bought from the vendor table at the SSCA
Gam in Melbourne the first weekend in November...

Yes, Skip...that's what I'm saying. A siphon break (vented loop) has no
impact on water being pushed through it...it only allows air into the
line to break the flow of water being pulled through it.

You can prove it to yourself by simply seeing what happens when you
flush the toilet in the dry mode.
