When the German museum lightship ELBE 1 returns back home to Cuxhaven from a trip, many people come to see how the ship gets moored at the landing pier. The other day I listened to a none-native couple´s conversation: She: "It must be a quite difficult work to turn a big ship like this in such a narrow harbour basin..." He: "That is no problem today - thanks to lateral thrust units." She (astonished): "Where are those lateral thrust units?" He (pointing at the STERN): "Well behind there, under the waterline! You cannot see them." She remained silent. Both now looked at the bridge and wondered about the man in the dark-blue sweater, who continously gave instructions to his helmsman: "Engine reverse - 5 degrees starboard - engine stop"! Even if it looks like a child's play, ELBE 1 doesn't have any lateral thrust units (and certainly none at at the stern), because she was built as early as 1948. The man with the dark-blue sweater is the captain and conducts the lightship with real hard work and precision to her berth ;-)
