The 239 ton De Wadden was built by Gebr van Diepen at Waterhuizen, The Netherlands in 1917 as a motor ship with sails and was one of the few schooners to have water ballast tanks. In 1922 the Hall family of Arklow in Ireland bought her and they traded this motor schooner from the River Mersey with coal, timber and grain, although in 1944, during World War II she made several trips to Portugal.
The Hall’s 228 ton motor schooner Cymric of Dublin, built as a barquentine at Amlwch in 1893, went missing with a crew of twelve on a trip from Ardrossan to Lisbon with 300 tons of coal in 1944. The Halls withdrew the De Wadden from trade across the Irish Sea in 1961. She was sold and went to the Clyde and was taking sand from the Kyles of Bute to Dunoon until the authorities stopped this work in 1977.
When I went aboard the De Wadden in 1980 she was in a poor state. The masts had gone, apart from a derrick, and the decks were tarmac. I was told she was running trips for anglers, but noted heaps of fresh sand in the hold. Whatever way you look at it, De Wadden was the last sail using schooner or ketch operating in Ireland or Britain, and because she was the last sail using vessel to trade regularly into the River Mersey the Merseyside Maritime Museum bought her in 1983.
