Franklin, a Basque-Breton captain, has always let himself be carried along by the ocean. His grandfather passed on to him his deep passion for the sea, and he was already sailing alongside him before he was even old enough to remember.

After becoming a sailor, the sea took him to the four corners of the world, where he experienced some of his greatest adventures. From Ireland to the Caribbean, he cut his teeth on all kinds of ships.

His knowledge of and respect for cetaceans and his encounter with the Shelltone Whale Project have led him to become involved in their study and protection, at home in the Basque Country.
