LOL, where? Cuba? You’re trippin,…
BUT, I agree that such “cat” could be considered a seastead. And why bother docking?? Drop the hook behind the mangroves in the Keys and people will come to you. Can make a reasonable $800 net/day on location. If chartered, $1800/day.
To start with. And move on.
BUT AGAIN, why a 128’ sport fish cat? For what? And why start @ 128’?
Why not “just” an 80’-100’ mobile floating island modular type seastead design?
That’s my “dinghy” 28’ cabin cruisers docked alongside on the port quarter .
Whichever comes first.
