"...always log when, where, and how much garbage that you dump..."

I know that there must be a good logical reason for this, but what it might be escapes me. Maybe to try to prove that you aren't the jerk dumping his trash overboard right off of that high dollar hotel's beach or something?

I suspected that fresh water would be right at the top of the list, glad that I have at least one or two brain cells working this morning. On that subject, I would suggest doing what RV boondockers do, carry a couple of collapsible five gallon water jugs along. I am sure that you will find lots of places you can dock at for free for a limited amount of time (like the WA state park where we are currently volunteering), with potable water nearby. Just dock, jump off, fill your jugs, jump on, and you're off. Our dock area even has a dump station for porta potties, so if you can figure out a way to use a blue boy, you would be good to go (pun intended again)...
