Glad you like your glorified cedar bucket, but there are in fact no composting heads for boats. The EPA has papers out on what is and isn't a composting toilet or system, and unless you use it, put it aside for 90 days to actually COMPOST, and then empty the sterile compost out, you don't have a omcposting toilet. You'd need at least two of them so you could alternate every 90 days, to really have a composting toilet.

What you have is a bucket that collects fecal matter, which is still "live" and still has to be disposed of someplace, sometime, and it ain't compost when you have to move it.

That the industry can't be honest about what it is and what it does--and doesn't do--speaks volumes as to why they haven't taken over the market.
Composting starts as soon as the "material" leaves ones body, and isn't "complete" until there's nothing left but inorganics (i.e., ash). Any line one draws before the organics are completely gone is arbitrary. There's nothing magical about ninety days. There are still plenty of organics left at that point. That's just the point at which most systems are "well enough" composted.

So, does a "composting head" actually compost? Sure it does. Does the "finished product" meet some EPA standard for minimal concentration of pathogens? Probably not. But, if you don't eat the stuff, so what? It's undoubtedly better for the environment to dump the product of a composting head where and when legal than it is to dump raw blackwater.
