What are you trying to flush? Tennis balls?

No, but pretty close.

Except that solid waste is 75% water...tennis balls aren't.
So the Y valve is_before_the holding tank? Isn't that illegal in many
areas?

Nope. It doesn't matter where the y-valve is, only where waste ends up.

Why would you go to a holding tank if you're planning to go offshore?

I prefer not to dump raw sewage into the ocean. Otherwise, I would
just crap over the side.

So why would you install a macerator if you don't plan to dump the tank
at sea? Or do you think a whole tankful is better for the environment
than a single flush?
