De Wadden is a three-masted auxiliary schooner built in the Netherlands in 1917. She was built by Gebr Van Diepen of Waterhuizan, Netherlands, for the Nederlandsche Stoomvaart Maatschappij (Netherlands Steamship Company). This company commissioned De Wadden and her two sisters in order to take advantage of the very lucrative trading conditions created by Dutch neutrality in the First World War, and it is vessels like her which provided the foundation for the continuing Dutch strength in the European short-sea trades. The world-wide shipping slump in the early 1920s forced her sale to Richard Hall of Arklow in the South of Ireland, and it is as an Irish Sea schooner that she is best remembered. From 1922 to 1961, De Wadden carried bulk cargoes such as grain, pit-props, china clay, mineral ores, and especially coal from the River Mersey to various Irish ports. Link
