i’m guessing these pleasure super yachts are not hardcore sea fairing vessels that might not handle sudden extreme weather at all well. also might not be captained by people that would do all the right things in those weather conditions.
obviously i have no idea if any of that is true
oddly enough i think the internet would have to behave in a federated way
content would need to be cached in connected areas and we would need to optimize use of the satellite connections to propagate content between federated islands
