Make sure the admiral is attended to if you know what's good for you!
I believe you do. Head and galley are hers!
You have choices.
The choices here provide a nice procelein style bowl, like home, but smaller. None are so simple to maintain and avoid breakdown however:
"vacuflush": even flushes with full flow, uses freshwater so no sulfur odor or SW odor, and use less water than marine head hand pump or electric pump, but expensive and requires space of vacuum generator tank in addition to standard holding tank, FW tank, and macertaor overboard pump (as usual).
Google "vaculflush" ought to find it there.
Marine heads are hand pump, or electric pump, no vacuum so you use water to clear bowl properly on a No. 2 trip to head! More water used. Sw usually.
To get the bowl height low, most of these have no built in holding tank, so always need holding tank usually 10 gals or so. I actually fit a 13 gal tank in my boat this year.
Remember, electric operation will not work w/o power.
Your boat probably had a marine head option I beleive, so there ought to be an empty stringer grid area now for tank, if you have a macerator and Y valve, that's where the compartment may be, as in my Salfish. Other Gulf owners will respond. If you look on teh GW weboset ate your year model, it will show the tank location in teh electricall diagram (I bet).
I did the vacuflush conversion, trips to head in style now vs. old sanipotti! Had to find the room for the vacuum generator combo vacuum holding tank, nothing is easy in boats. They make a nice compact one now but it does take up space.
