My Mother always told me to plan a few days ahead of your departure time. That would give you time to eliminate half of the clothing you packed and double up on the money. It works well so far.
Ha, good one!
I used to use a French Press on the boat, but even with using one of those Rubbermaid type spatulas to "pre-clean" it, I still found that it took a lot of water to rinse it out (supply limited). When friend broke mine accidentally, I decided to try something else.
Now I'm using a Chemex, which is essentially a drip coffee maker and has filters. Even though I liked not using filters, the water saved in not cleaning the press pot has driven me to them. I like that it is glass.
I think if I were to head out again, I might get a drip filter to fit over a metal Thermos™ I don't like that they are plastic and you are pouring boiling water though them, but maybe I can find one that isn't. Or maybe I'll just lug a smaller Chemex.
I drink most of my coffee cold, so I've also been thinking of trying cold brewing, but haven't yet.
