ON a boat that had the space the RV Sealand , with direct drop into a holding tank would be my first choice.
IF the tank were above the WL, the 3 way valve could select GRAVITY (when permitted by the great Poo Patrol Police ) for a trouble free set up.
The deck wash hose (or a bucket) could be used in the "pump out position " to get a really clean sweep of the holding tank.

*Good points.* On my Albin the holding tank was glass with gelcoat interior.* When I was renovating...all the pipes going into it were rotton so I cut a rectangular access plate on top and installed the new inlets in a thick piece of plexiglass and reinstalled with a gasket.* When the tank was opened I cleaned it out and the gel coat showed whiter than the cabin sides topsides.
Now with the plexi top a quick glance when I'm in the engine room checking things lets me know level with no guessing or problematic sensors.
