Hi Tom,
I carry a portable crapper called a boom box rather than the potti that came with the M15... We use it for extended whitewater trips on rivers were carrying out all waste is a requirement...
I'd like to hear more about this (sorry if it's a bit indelicate...). I've been considering the simple bucket for my next boat (not a Monty, but still space-challenged and the head is in some prime real estate right now). I was remembering back to my whitewater days, during which I took a raft-supported trip down the Salmon River and we used 5-gallon buckets. We used some sort of mixture (lime?) that we sprinkled in to the bucket between uses and it actually wasn't too hideous. I mean, the first person to use the bucket has it just fine, but assuming you can't immediately jettison the contents, then what? This powder kind of ... stabilized things since in that case we actually had to use each bucket until it was full. Of course a smaller container would be much better for a small boat with one or two people on it... So, I'm curious to know more about the boom box, and also if you use the powder I remember and what was it, actually? I never knew. In the case of the river trips (in case anyone's still reading ;-), we had to pack *everything* out, so we just used the buckets until they were full, then put the lid on and ran a bead or two of duct tape around the joint between lid and bucket, just for extra security. Then we started a new bucket... And to think I was writing about ice cream and 20-year-old port just yesterday :-) --- R.
