Ship model "Mentor", built by Sten Bergwall in 1996

3-masted barque, built in 1876 at Slussens Varv on Orust of oak and pine. Homeported in Mollösund, Gothenburg and Råå. Length over all 37.8 m, beam 7.6 m, depth 3.9 m. Despite her modest size, she sailed the seven seas during her time in Gothenburg. In her later years, a windmill was installed for the bilge pump to keep the vessel afloat. When the windmill was in operation, a characteristic sound, onk-onk, was produced, which led to vessels with this labour-saving mechanism being referred to as "Onkers" by the English.
The vessel stranded in 1916 in the archipelago of Karlskrona and was "scrapped" after long and faithful service.
