British solo round-the-world sailor Dee Caffari happily admits that you need to be a little bit ‘mad’ to take on long-distance sailing. And she should know: Caffari became the first woman to sail single-handedly around the world in both directions after completing the solo round-the-world race, Vendee Globe, earlier this year. “People say you must be mad — and there probably is an element of truth in that,” the 36 year-old told CNN.
