Water efficient head

[Monterey10]

I have a 25' boat with using a Raritan PHII. The holding tank is pretty small, maybe 20 or so gallons. With my wife and I on the hook, it seems like we can only spend a night or two before the tank is full.

An acquaintance of mine who has the same boat, put in a Vacuflush. He reports that the Vacuflush uses very little water and his holding tank lasts for four to five days. Another friend uses a crown head, and he reports that his holding tank lasts quite awhile.

So, I request your opinions on this situation. My wife and I are tiring of the marinas and would like to stay on the hook longer. I'll have to find a more efficient head to preserve my holding tank space. Besides having a smaller holding tank, the bathroom is limited in size, so, I'm not sure a larger crown head would fit.

Thanks in advance.
