As I understand it here in BC there are not yet requirements for pleasure craft regarding overboard discharge except in Marine parks... Not to sure about this. I also understand that we cannot enter Washington state with having a holding tank. Is this true? If it is would a composting toilet meet their requirements? And is there any one out there that has used one on board? If so what and how much and are you happy with it?
I hadn't heard of the airhead until now. The one I had been looking at is from !you know what.sun-mar.you know what! and certainly seems much bulkier... 23" deep. I also like the solar fan option on the air head. My aunt uses a composting toilet at her recreational cabin and is very satisfied with that but it is definately big. However, they have found, if they don't pee in it so much things work much better and it doesn't smell. Seems like you could easily work around that on a boat....
