The patí, the Catalan catamaran, is an iconic artisanal boat sailed along our coast with a unique feature: it has no rudder. We will sail on a patí in a regatta around Menorca that culminates in the America’s Cup, learn about its origins and the people who sail it, show how it is sustainable, and reveal its uses as a scientific tool. A documentary that combines the excitement of sailing and tradition with an urgent marine conservation mission.
