Tánana, being ready to set sail on Yahgan language, is the return of Martín González Calderón, to heart of Cape Horn. He’s a Yahgan craftsman and one of the last of his people, the Yahgans, who have lived in Tierra del Fuego for more than 6000 years. Long trips made with his parents let him get the deepest knowledge and secrets of ancient navigation. However, this way of life was violently stopped, due to the interventions of Chile and Argentina’s states. Since then, the few Yahgan people remaining, cannot sail as before. Forty years later, moved by the need to transmit this unique wisdom, Martin prepares a new journey. With his ability as a shipwright and the help of his family, he builds a suitable boat, while instructing them about this important skill. Thus, their journey begins through the ruins and vestiges of his old life, reliving his memory of the territory, with it’s dazzling history, stunning wildlife and geography. After the purpose of leaving this legacy, there is also a special desire to perform, to round the False Cape Horn, as he did as a twelve years old boy with his father. In that direction he traced the route, hoping to revive those moments of deep ancestral connection with the stronger seas of the world.
