Anyone have any comments, pro or con, on composting toilets eg. the Airhead, on boats?
 
What do you do with the urine? I haven't ever seen a single boat with one. I did read up on them but they don't seem to be able to handle much in the way of volume.

I know of a couple of boaters who have installed composting toilets of different types and claim to be happy with them. I haven't had the opportunity to use one of these systems or take an extended trip with one.

The Airhead is classified as a Type III MSD: just like a conventional tank system. Waste is stored onboard and removed from the boat at a later time. The Airhead resembles a Portapotty hybrid.

I considered composters briefly for my boat but decided on a Type I MSD system instead. We have used a Purasan system for several years and wouldn't switch to anything else. If you install a Purasan in a tankless system then you have unlimited flushes (minimum two minutes apart) with no stored waste.
 
"What do you do with the urine?" Pee over the leeward side.
 
The urine is collected and stored in a separate compartment for disposal as needed. The disposal of solids can be weeks or months depending on usage.I know two people that have them at our marina. Both really like them.
 
Hm. I know a man who can't hit a 12"x18"-diameter hole reliably and without splatter. Somehow I think this separating urine idea lacks practical merit. The lee rail sounds better- if it happens to be often enough underwater.
 
Mimi, how're things going? Haven't heard from you in a while. Did you get any storm damage? How's the houseboat? Drop me a line when you get a chance; I misplaced your e-mail address and phone number.
