Jean-Jacques Savin left the Canary Islands off the West African coast on Wednesday in a refined, barrel-shaped capsule that he had used for months.
He travels at "two or three kilometers per hour" (one to two miles per hour) and intends to (literally) move across the ocean using currents (literally), he told the AFP News Agency in a telephone interview after he left.
He stashed a bottle of Sauternes white wine and a block of foie gras for New Year's Eve and a bottle of Saint-Émilion-red for his birthday in January after AFP
A porthole in his temporary home will provide much entertainment for him to watch the passing fish, and Savin drops markers on his way to allow the international ocean observatory JCOMMOPS to investigate ocean currents.
The ship contains a bed and a small kitchen and some storage space.
Savin is undecided where he hopes to end. "Maybe Barbados," he told AFP, "although I really like being a French island like Martinique or Guadeloupe, that would be easier for the paperwork and for getting the barrel back."
About 2,850 miles separate El Hierro from Barbados, but Savin said his ship has behaved so far "very, very well".
