"Marvin Creamer (born January 24, 1916) is an amateur American sailor noted for having sailed around the globe without the aid of navigational instruments. From 21 December 1982 until 17 May 1984, a total of 510 days at sea, Creamer and the crew of his 36' boat Globe Star circumnavigated the globe with no nautical aids, not even a compass or watch."
I seem to remember that his tale was told in the very first issue of 'Ocean Navigator'. There may also have been a book..?

About a decade ago an adventurer did a single-handed circumnavigation
with absolutely NO navigation instruments. I remember that he timed
his passage of Cape Horn to allow him to judge that he was at a safe
south latitude by this "horizon grazing" technique. Unfortunately I
have no further recollection of the name of the boat or its skipper.
