Even the best sailor goes through all eventualities one more time before embarking on an adventure on the high seas. Yvan Bourgnon did the same before he set out to sail around the world for three months without technical aids in a 6.30 meter small catamaran. No sat nav, no GPS, no cabin, no protection, just him, the wind and the sea. What sounds almost cheesy and romantic was a danger that no one had exposed himself to before. And then what happened, even an experienced skipper like him would never have expected.
