Toilets. A waste of space?

The composition may be the same, but the consistency is very different. The output from a marine toilet disperses quickly and will be undetectable within a few minutes, with any unfriendly microbiology diluted to safe levels, at least in, eg the Solent, where the water is changed by the management twice a day. In a Mediterranean bay with no tide, however, a holding tank is a good idea (legal requirement?)
Yeah I am hoping to take my boat to the med when its finally done, so cant imagine not finding a solution to fit a holding tank in there somehow.
Bit how do you work the rest out? Its still shit and paper. Whether in clumps or bits is pretty irrelevant. A marine heads simply forces waste out of a pipe straight into the sea. There is no attempt in one to sanitise the waste in any way. Not to mention, that many folks with heads will be putting bleach down them to clean them. Far worse in the sea than compostable waste.
I think we all agree that disposing of toilet waste in bays and harbours and near swimming beaches is not a nice thing.
I dont think that there is any environmental or virtue kudos to be had in using one over a bucket though. Just privacy and comfort :)

I have seen a reference to a sailing boat being fitted with a composting toilet, and the owner being happy with it, however I don't know the details but I found one reference:-
Best waterless toilet for narrowboats, widebeams and sailing boats
Anyone with any experience out there?

I sailed on a yacht with a composting toilet once, but frustratingly I can't remember what or when it was.

I could probably work out when and where by process of elimination but life's too short.

The fact I don't recall detail suggests it worked fine.

It's much more useful reply than I had expected! I guess it's all concerned with the process of elimination.

Yes, the composition is the same, but it disperses much more readily when macerated by the pump. Throw a turd and some paper in the sea and it's still a turd and sheets of paper; it'll take a while to disappear. If it's minced, it gets spread out and quickly diluted to the point of being undetectable.
