Line Crossing CeremonyAnd during her voyage to Japan, this ceremony is also done on board U-511 when she crossed the Equator line in the Atlantic Ocean.I wonder if they would be putting on clothes any time soon...This is a ceremony held when a ship passed the Equator line. In Japan this has also been practised since before war.Other than those responsible for navigating the ship, all crew went to the deck, got naked, and received their baptism.
