I can only assume it’s Tamata as he never made it to Polynesia with neither Marie-Thérèse nor Marie-Thérèse II and it’s obviously not Joshua. I think it’s the first time I’ve seen an interior image of any of his sailboats, even though I knew they were all barebones, according to his descriptions.
According to the image caption, it’s a conversation between Florence Arthaud and Bernard Moitessier on board his sailboat in Polynesia. Two different generations, but with the same desire to preserve the marine environment.
