(machine translated in 2023) After years of working as shaper for F2, Patrik Diethelm and his wife, multiple world champion, Karin Jaggi, started their own windsurfing brand. After stories in early 2009 that Patrik and Karin no longer worked for F2, the news came in early October 2009 that they were going to start for themselves. Simply under the name Patrik Diethelm.
Since 2020, Patrik also makes sails.
