It's creative problem solving. The Zopilote class has brought the most attention to me, although that was not my plan. Circumnavigation turned out to be a bigger deal to other people than I thought it would be. Joan and I don't own vacation homes. We don't go on skiing vacations.
Some people own several homes or a fleet of collectible cars.
I don't have any other hobbies. I focus my recreation time on my boats. That doesn't mean we don't do other things. But we don't have a lot of expenses that are not related to the boat. In order to do a passage like this, you should have a crew, professional or otherwise.
