Flexable versus Ridged holding tanks
When I bought Privateer she originally had a flexible holding tank
(Jabsco Par 15) which still had crap (pun intended) in it after the previous owner had her up on the hard for almost 2 years. Needless to say I deep 6'd it. The new marina requires holding tank for liveaboards, and I was thinking about replacing the old with a new flexible, but I have no experience with them. Input would be appreciated.

I would avoid ridged holding tanks, as they are much more difficult to clean out than smooth tanks are. If you're asking about flexible vs. rigid tanks, I would probably say that rigid tanks are the better choice for most boats.

Take a look at:

You want a holding tank that lets the poop degrade _aerobically_. So there has to be air on top of the waste.

Use a rigid tank. Usually, _somebody_ makes something that fits in the available space.

I would point out that Peggy Hall is probably one of the foremost experts on marine sanitation systems there is currently.

I would also point you to this link, which I believe is also by Peggy, and does mention the negative aspects to using a flexible bladder as a holding tank, especially on a sailboat.
