Holding Tank Conservation methods?

The new boat has an 11 gal holding tank, clearly too small but we are trying to get the most out of it. The head is a manual Jabsco which I have measured 24 pumps/gal.

With 2 people we are filling the tank in 3 days. That seems twice as fast as I would expect and we are trying to conserve.

So far I have found using fresh water from the sink to flush reduces fill rate but no measurements yet.

Any useful tips on extending the holding tank fill rate?

I have heard the VacuFlush claims to low water usage and wonder about actual use.

Flush less. Y'know,if it's yellow, let it mellow, etc.
When you do flush, use fewer pumps. three or four should be enough.

Splash in a cup of vegetable oil once every couple of days. Less friction means less flushing.

Use less paper.

We have a 12 gal holding tank which we empty every couple of weeks.

mothers frown on letting you borrow their infant to wipe your backside, so unless you have one or two washable infants of your own, T37's idea may not be practical.

Now that is impressive.

Ours is 16 gallons, and we can go about 5-6 days, or 3 weekends, with our family of five.

We do not add water for every flush -- i.e. we pump fluids down until the bowl is virtually dry. If it's just fluids and t.p. we're dealing with, we'll only add extra water to the flush about every third time.

Above applies while at anchor. If underway, we do flush/rinse completely to avoid stinky spillage if we get jostled about.

Solid waste gets the full flush treatment, regardless.

#1 just pump it dry and maybe 1 pump to put a little wat in the bowl. #2 I do not put the tp in the bowel but roll it up and put it in out trash. however my wife make up for my lack of tp even for #1. Its a guy/girl thing. I gave up on trying to change her habits. Of course she does complain she always gets stuck with an empty roll but that's because she uses it more.
