How about solid copper pipe with short sections of that expensive hose just
to join to the thru hull and toilet itself etc....
Waste odors wont seep thru solid copper piping.
Shoot, you could even JB weld epoxy the pieces of copper together instead of
using metal solder.

I'm sure there's a good reason - but my initial looking discloses two
basic
types of sanitation hose.

Both claim the same purpose (keep the stuff and the odor inside while on
the
way outside), but there's one which is 3x the price of the other.

What's the difference, other than the obvious price? Easier to use?
Won't
let the odor/seep through, ever, vs some number of years? Stays whiter in
more conditions?

The difference, in boat money terms, is pretty insignificant, I'd say
(some
couple-three hundred bux for the standard 50' roll), but if it's not
needed,
I can use that couple-three somewhere else.

Anybody used both (e.g. "148" vs "Sealand") who can give experiential
input?

Thanks.

that you are quite alone on a great, wide sea, it is apt to occur to
you that in the general scheme of things you are merely an
insignificant speck on the surface of the ocean; and are not nearly
so important or as self-sufficient as you thought you were. Which is
an exceedingly wholesome thought, and one that may effect a
permanent change in your deportment that will be greatly appreciated
by your friends." - James S. Pitkin
