The story of the Sterke Yerke starts in 1974. A group of boys from the Frisian capital Leeuwarden jointly build a raft. It gets the name of Sterke Yerke. The raft will sail the Frisian lakes and the Wadden Sea in the following years. Two more rafts followed Sterke Yerke II and III. The last and third raft “Sterke Yerke III” was built for the Frisian lakes but also for the Atlantic. This website describes the history, the tours and the pollution. The story is supported by photos, video images and articles.
