A chap by the name of Donald Crowhurst in an early (the first?) "around alone" sailed round and round in the Atlantic on his multihull, "pretending" that he was sailing the race legitimately, “around the world", and was going to sail to the finish after an acceptable time, disappeared overboard, (probably went mad from guilt and committed suicide, is the consensus). Does that count as a "lost at sea from off of a multihull” in a solo "around the world?
