If I were starting from scratch again, I would follow the example of Roger D Taylor, and his two Ming Mings.
In a nutshell, he takes a discarded old
boat that he gets for nothing, and transforms it into a bomb-proof
blue water vessel that can easily be sailed
single handedly anywhere in the world. He mainly explores the high latitudes in the Atlantic, up in those arctic islands that most people have never heard of.
He has writtten several
books on the subject and has a good series of videos on YouTube.

He puts a lot of sweat equity into his boats, so not a path for lazy people, but if you have more energy than
money, it’s a proven option.
