Déjà vu? I thought I already responded to your query Annie.
Yes, there are many of us here who cruise
with composting heads. They work
great for smallish boats with two, perhaps three full time crew members. Do you have any specific questions? I (and I’m sure other compost users) would be happy to respond.
As others have said, there are a number of threads where this has been previously covered, but I don’t mind starting a new one. Or you can find an old one and revive it. Or whatever… this is a discussion forum after all, not a library or database.
