Head, to compost or not to compost?

We are looking into this, they are expensive, but quite possibly the best thing since sliced bread.

The thought of urine and feces in a tank on your boat grosses me out. And having to repair it grosses me out even more. However, the thought of feces in a medium like moss doesn't gross me out as much, probably, because as a girl who has camped in primitive areas I know how to use the potty outdoors.

In the interest of time and necessity, we have just ordered our composting head and will install it on our new boat soon, yes the boat we just purchased a few days ago. There are some dilemmas with the head on our new boat, the biggest being that there is no holding tank and the marina we have placed it in requires just that, a holding tank. The composting head would operate as a holding tank, it has one for urine and one for feces.

I've never really operated a head, so I'm about to learn. And neither of us have used a composting head. We've watched the video on how to install it and how it operates, and read some reviews online. This is something completely new we are getting ready to explore, potty on a boat. It is pretty important to know how to do this (especially when children are young - getting them out of diapers is a huge hurdle), and it is the first official thing we have bought for our new boat.

Its gonna be interesting, we'll have to teach the children how to use the potty in a different way, pee with valve closed and poop with valve open.
