if you can find places to make offshore moorings i'm sure you can make money out of it... i mean offshore as in "outside of the jurisdiction of an established government navy"

the hard part is facilitating those essential services, food supply, water, power, etc

i think one of the ways to approach this is to think outside the box on solutions especially energy and heating

the rest is ordinary transport problems, but power, and its use cases, imply a different way of solving the problem out in the seas than throwing wires around, much more practical to talk about fuels, generators, powerplants and other suchlikes
