The Hans was built at the Gebr. G. & H. Bodewes yard in 1910. The length of the vessel was 25.86 meters, the breadth was 4.96 meters. In the 1920s she was sold to a ship owner in Norway. In the 1930s and 1940s, the ship was converted multiple times: from motor ship to motor yacht and then changed back again.
After many years in Scandinavia (sailing under different names, respectively: Neptunes I, Bølgen, Tekla and Ulla Christ), the vessel returned to the Netherlands in the mid 70’s. After that, she was used as a houseboat and a workboat at the same time. In 1993 she was sold and renamed Ero.
