Re: Composting Toilets vs. Holding Tank
Here is one link to a gravity tank install. If you read the whole thread it gets off track because of the sink drain arrangement which I wouldn't use. A tank system totally separate from the sink is the proper way.

Here is the system Peter Jacobs installed on his Albin Ballad with lots of pics - he made the tank as well. Easy to follow. Scroll down a few pics for the start and it continues on the next page - "more progress pictures" link at the bottom. Peter's previous boat, an Albin Vega also had a gravity draining holding tank and it also worked well.

thanks. that may be a less expensive ( read: more doable ) option than a composting head. it's good to have more options from which to choose.
