We buy draft (box) Merlot and imbibe from "10 foot" wine glass. At a 10 foot distance, they look like a classical stemmed wine glass. Up close, it's an acrylic wine glass enclosed in a large acrylic tumbler with a travel mug top to prevent spills when it tips over.

Hint: they're spill proof, not leak proof.
I love it! Much better than the flexible silicone glasses that work well for hiking, but won't fit in a cup holder on deck
I just leave it in the case and try not to make it too easy to get at. On a similar question I asked Sir James Hardy what he recommend to take on an extended cruise. Sir James is a well known sailor and wine maker in Australia. He recommended young robust wines with really good corks. I now go for the selwyn screw tops.
Another neat option is to distill the wine and store it as cognac. It stores better than wine and you can keep about 6 bottles of wine inside of one cognac bottle. We can say that energy density of cognac is more conductive to storage.
Many ways to skin a cat.
Nice idea, I guess later you could just add the water back in, maybe even doubling the quantity for even more added value.
My setup is pretty pathetic all booze into the cooler where it's cooled and reheated cyclically depending in the presence or absence of ice, respectively.
That being said, my Ericson has a bilge so deep (2ft)!!! Anything stored there would be water temperature. I never thought about wine storage there! Thanks!
