Stig Vilhelm Tiedemann was a Swedish sailing and motorboat designer. He worked as a boat designer for Jac Iversen, Knud H. Reimers, Uffa Fox in Great Britain and, for a time, for the Swedish Naval Administration. Stig Tiedemann designed a number of sailing boats.
In the 1940s and 1950s, however, he concentrated mainly on designing large motorboats and became known for his so-called "Tiedemann cruisers".
In 1945, he apparently designed the P510 camping boat on behalf of Archimedes. The corresponding drawing is stored in the digital museum of the Sjöhistoriska Museet.
Information about his works can be found on Swedish Wikipedia and on the website of the Swedish Tiedemann Club.
