The Hoop op Zegen, is a sailing cargo ship, built in 1897 in Hoogezand, the Netherlands. Until 1918 she sailed on the Waddenzee area, from Delfzijl to northern Germany. In 1919 she was bought by Albert Stroomberg, he named his ship after his wife, Gretha. With his family (wife and four sons), he crossed all the canals in the Netherlands to make a living. Although his family forced him to buy a small motorboat that was able to push Gretha, it remained a sailing cargo ship until 1974. In that year Albert Stroomberg died and his wife also left their ship. The family sold her to Ton Ebben and his girlfriend Marianne. They wanted to live on an authentic ship, restored her, resulting in a documented sign of authenticity by the city of Haarlem. Unfortunately, forty years and a few owners later the ship was in a very poor condition when Gabe de Vries and his wife bought her in 2014.

He restored her again into the original state and renamed her Hoop op Zegen.
