Jeff,

I was reading a recent post on a very long thread on this same subject on another site I frequent and found a link: http://c-head.com. They commercially manufacture such a product for about half the cost of the competition and it looks to me to be twice as well thought out. Maybe enough to justify the cost.

Getting back to a thread of a while back:

Recently I got rid of my smelly, dificult to keep clean, marine toilet, and thus rid of two holes in the boat. 

I am just back from a weeks cruise and tried out a 'haybox'.  I had read about composting wc so thought it worth a try.   It is simply a large tub with sealing lid, over which is a toilet seat.  Inside the tub is an Ecover biodegradable plastic bag. Line with a layer of grass clippings and after use a layer on top.  Dispose, well out to sea, by placing a rock in the bag and dropping over for the fishes supper. 

The smell was similar to a farmyard (suprise suprise) not offensive,  and none with tub lid on.  Success so far.  It was used for only a couple of days between disposal.  Perhaps anther couple of days would be ok.

 

Mark, that's encouraging.  I removed the "PnP" during the rebuild of Sea Elf and plan on using something similar to your 'haybox'.  Just wondering, since you're heading offshore to dump, could you eliminate the bag and just dump the contents overboard followed by an over-the-side rinse?  My plan for now is to use the bucket and wood shavings and when time to empty (still inside the three mile limit here in the States) I could dispose of it in the facility used for dumping porta-potties followed by wash down from the hose nearby....   thanks for posting...I had been concerned with the odor, but it sounds like that won't be too much of an issue.


Mark, after posting a reply, I checked into TinyHouse Blog and look at what they had on the top of the list for today!

Well, yes you could just wash it out, but could be messy and leave smells in the tub.  the advantage of a bag is that when full or there too long,  knot the top untill somewhere suitable for disposal.  At £2.50 for 10, not cheap as plastic bags go, but at max of 25p a 'dump', not expensive.  Definately with the $10 challenge!
