A couple of off the wall (OTW) questions about boat sanitation systems.
These questions could be considered wierd I guess, but are serious none the
less.

Regarding inside the three/twelve mile limit:

1. It's legal to urinate over the side of the boat afik. Would it also be
legal to urinate through a cabin window (port) which could be opened and
closed?

2. Would there be a problem with using a holding tank constructed sort of
like an outdoor toilet --- sliding gate valve in top of tank, sit down, open
the valve, defecate, close the valve?

3. What about a toilet seat hung off the transom? Would it be legal to sit
on that and defecate directly into the water?
