Composting Toilet - there is a compact model made for boats, but a blackwater tank is required for excess urine, which can be emptied at any sani-dump station
The simplest method is to lay out some newspapers. After defecating, wrap it in newspaper, then tie it up in a grocery bag. Dispose of it in the nearest garbage can or dumpster.
Newspaper method #2, wrap in newspaper with sawdust (to absorb moisture) and a handfull of soil, store outside where it can dry up w/o smelling, turns into a humanure compost burrito, yum!
