In 2012 Stef fell in love with a Russian riveted boat, the Amur. Originally build by the factory Knaapo, an aircraft factory in Russia that were also making boats just before the Cold War.
Because the boat was built with aviation techniques, Stef added some Dutch Fokker aviation parts, such as an 1,5 meter longer rear formed by an cargo hatch from a Fokker F50. On the front we find a maintenance hatch also from a Fokker F50, also there is landing lamp from a Fokker F100 that is recessed in the desk and now used as a searchlight. The boat has been completely polished by hand fitted with an interior of Citroen Maserati SM, this boat is now for sale.
