The Bésixdouze was a sea vessel belonging to the science expedition, a group of six French researchers including Danielle Rousseau. It wrecked near the Island during a storm on November 18, 1988 while the expedition was attempting to locate the source of a voice repeating the numbers over a radio transmission. Little is known about the vessel, but it carried at least one inflatable life raft, which presumably saved the researchers during the storm that had caused them to abandon ship. ("The Little Prince")
