I’d start with getting some sort of sailing accreditation. RYA is the gold standard, Competent Crew is an easy 1 week course that will give you street cred.

You can then use a site like https://www.findacrew.net/ to express interest in a passage.

If that’s not your vibe and you want more control, consider investing 20-30k in the RYA Yacht Master with commercial endorsement and do a boat delivery from/to the locations you are looking at.

Or, drop $100k+ on a bluewater monohull and life free. Really, it’s true freedom, sailing may capture you just like Bitcoin. There’s nothing like a night passage staring at thousands of stars, alone in the dark. It’s unexplainable. Please do it if you can.
