If you must have a marine head, LaVac is, indeed, the way to go. If you in a

sense. Some would say even if you're NOT in a no-discharge zone.

Our Catalina 27 came with a porta-potty and it has
been a good way to go on that boat.

We own two Raritan Sanipotties right now, and one
is doing duty on the Irwin right now while I'm
working on the sanitation system. The other is on
the Catalina 27.

I thought seriously about just taking out the
electric toilet and holding tank and putting in
the large Sanipotti. It works just fine while we
are in the marina, because we just walk it up to
the bath house and dump it in the toilet.

However... When we are out at anchor, in a
no-discharge zone, the 8 gallon tank of the large
sani-potti is going to be a problem. I know from
experience how long it takes to fill it up, and I
don't want to have to go find a place to dump it
that often. That's why I'm considering a 42
gallon holding tank, and a toilet setup that is
miserly with water.

Thanks for the thoughts,
