Any and all boats have sailed around the world. There is no perfect boat
; nor is there any unsuitable boat. Logs
have sailed thousands of miles. Cal
20s have circumnavigated. Go with what you can afford and feel comfortable with.
We did it in an old westsnail 43 eons ago. It was suitable for a family
and could be single
handed. For third world exploration it was perfect. Nowadays if we had megabucks would go with a twin keeled aluminum
Our friends have gone around the world in a 93 foot mega yacht. Would not be our style but it suited them. On the other hand, we met a couple that did it on a dana 24 with no problems. Enjoy. A blind man circumnavigated. World is round. Not a problem.
