Composting Toilets?

The past week's experience / expense with our electric head(s) has me contemplating one of those marine composting toilets. The ones I've seen up close have been butt-ugly (pun intended ) but I figure I could use some creative cabinetry to improve appearance.

Anyone using these who would care to comment? I know they're out there as I saw at least 2 boats that had them installed during our boat search. Are they worth it? How do you handle the 3-inch vent requirement & power draw?

Was thinking I'd leave one head as-is and replace the other with a composting unit.

Suggestions / recommendations would be greatly appreciated.

We had a neighbor that had one in the slip next to us and the soot it sent out drove us crazy.

I have two heads on my boat and I am seriously considering and airhead to replace one of the heads. I would like to hear more from people who have an Airhead aboard thier boat. One thing about an Airhead, the law will find it difficult to mess with you concerning unlawful discharge.

If the advertising is accurate it sounds perfect, no smell, no thru hulls, no plumbing, never block and legal everywhere. Just would like to hear from someone who has one.

Air head

I put an Air-head on our Hunter 37 cutter about a year ago. We are not full-time cruisers (yet), so the head gets only occasional use. After a year of occasional weekend use I can make the following observations. 1) the installation was much easier and much cheaper than replacing our 20 y.o. Wilcox-Crittendon would have been. 2) We haven't emptied the compost bin yet, so I can't comment. The stated capacity is 80 "deposits", so we have a way to go. 3) The vent fan draws 100 milliamps, so our 50 watt solar panel keeps up with the fan running constantly. 4) There is no smell. 5) There is no pump-out or jammed macerator pump. 6) the only downside so far is if you have several women crew, all drinking beer, the small pee-tank will fill rather quickly.

Do you think it could process two per day? Assuming two people aboard full time.

Not a Compost, but does anyone have any experience with an ECIS WC5 or WC16. ECIS is a division of Eberspacher.

compost head

I have built a version of the airhead. Works well now that I have the ergonomics and bugs worked out. The vent pipe should be higher than your head so the wrong wind won't blow the smell your way. Extensions can be used in port. With a weather cocking vent cap ,I haven't used the fan except when dumping. A turbine would work well. Painting the vent pipe black may create a thermnal draft in the sun as it heats up.
The peat moss under moss covered logs works well for composter. Its far simpler and ligher than a regular head.
They are overpriced for molded plastic but easy to build. It is labour intensive to build a one off. If you have time and little money, building on eis simpler. If you have money an dlittle time , buy one,altho I have heard they are back logged 8 months on orders.
They will become extremly common. They sure beat hell out of holding tanks. They even leave you something to mail to the politiocoes .

Any recommendations as to which composting toilet is best for a small boat with a small crew?

The idea of intentionally storing sewage and then waiting for it to decompose is a pretty repulsive idea. I think you would end up with more sewage than you can store before it has time to completely decompose.

Have you considered a Lectra-San unit?
Raritan Engineering | Waste Treatment

I have a Lectra-San onboard and it is pretty reliable as long as you treat it as directed from the manufacturer. Like all heads and this treatment system in particular, the only thing you can put in it is stuff you have already eaten and easily degradable toilet paper.

Decomposed sewage still has all the nasty bacteria that you do not want to put into the water. At least the Lectra-San unit sterilizes it before it is disposed of. Ideally though, get a pumpout tank if you have a place onboard for one.

Forget the heads that burn it into ash like the Incinoet. Nobody wants to be downwind of a crematorium for sewage. Incinolets are plain old nasty.
