Properly installed and maintained, there shouldn't be any odor. It's
only when portapotties aren't properly maintained that they stink. A
lack of proper maintenance is MORE likely to cause a marine toilet
toilet and remote holding tank to stink--and especially the hoses
connecting them--than a portapotty. Use a product in the portapotty tank
that suppresses odor...have it pumped out regularly...rinse out the tank
with each pumpout--much easier to do in a portapotty than a remote
tank--and you won't have any odor.

I could seal off a 2x2ft head in the cabin if that would keep
the air fresh. On pocket cruisers people used to be able to put the whole
unit outside in the cockpit at night. Now I assume it has to be bolted in
to keep people from dumping it over the side. Can't even take it home at
the end of a weekend cruise and flush into the municipal system?

Nope...not in Canada. But's it NOT that hard to maintain...honest!
