In the summer of 2022, Andrea Fantini and his crew mates were sailing towards Tangier on the Moroccan coast at the start of a global regatta, the Globe40 race, when one of them suddenly shouted: "Orca! Orca!"
Fantini saw a tail in the distance, and then a huge orca rushing straight towards them. "We saw the first orca coming, then the second, then the third, and then we were surrounded by orcas," he recalls.
