1883: Ten years after Holland America Line was founded, the “dam” suffix was officially adopted for the names of HAL passenger ships. It is a tradition that is still being honored today. Most of the HAL ships are named after cities in Holland or the dams that cross many of The Netherlands’ rivers and allow for irrigation. Ryndam, for instance, is named after Europe’s famed Rhine River which flows from Grisons in the eastern Swiss Alps to the North Sea coast in the Netherlands. It is one of the longest and most important rivers in Europe.
