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.
