Neil, I have a portapottie that fits in our M-15. I don't intend to use it anymore. I have found the PETT portable toilet and it makes a portapottie seem like a real PITA http://www.thepett.com/ We even use the bags in the marine head on our Flicka. Works great. No fuss, no mess, no nasty crap splashing all over. I'll never go back to a regular portapottie. Rik On Sun, Jan 3, 2010 at 8:22 PM, <ndorf@surfbest.net> wrote:

Quick question,

I want to put a porta-potti in my M15, and I have read all the information on the forums and M boat related sites. I understand that the Thetford 135 more or less fits, once coaxed with a soak in some hot water, then weight and wait.

My question is, given the expectation that the fit will be tight in the sunken well where the 135 will sit, will I still want the "Marine" version of the 135--which has a secure-down kit--or will the standard one do just fine?

I'm not sure there is really much difference in price, and my concern is also that, without actually seeing one of these, would the secure-down kit actually get in the way?

Any advice?

Thanks, and Happy New Year to all,

Neil Dorf Roseville CA M15 1985

Neil, I have an '82 M-15 and the Thetford 135 works just find for me. The weight of the water in the tank (for flushing) seems to be enough weight to keep the toilet from going anywhere. Granted, I have not been in blue water with 15' swells, so I can not testify to rough sea conditions, but on a typical 4 day sail with moderate weather, I've had no problems.
