Agreed. That is what I have.

With a three-valve manifold, and careful selection of open and closed
(*grin*), I can discharge from the toilet 1. into the holding tank, 2.
overboard through the Electroscan (current generation replacement of
Lectra/San)(where that is legal - outside of properly designated No
Discharge Zones), or 3. directly overboard (where that is legal - well
offshore only).

Once in the holding tank, I can pump-out through a deck fitting or
gravity drain directly overboard. Incidentally, I specifically spoke
to Raritan about discharging through the Electroscan without operating
it to simplify my installation. They strongly recommended against it.

Also, no chemicals are required for either the Lectra/San or the
Electroscan as long as the salinety of the flush water is sufficiently
high. Inshore I use fresh water to flush so I dump some common table
salt into the bowl with each use. That works fine.
