Deputy Editor in Chief surf
Stephan Gölnitz comes from Bochum and had Holland as his home windsurfing territory for many years before moving to Munich in 1996 for the job of test editor at surf magazine. The materials engineering graduate worked as a surf instructor on the Ijsselmeer during his studies and competed for several seasons for the Essen sailing team in the Surfbundesliga and the Funboard Cup. He completed a traineeship at surf-Magazin in the test department and since then has actively accompanied almost all tests on the boom and for more than 10 years also as a photographer. Stephan has covered many thousands of test kilometers, mainly on Lake Garda and in Langebaan, but also in Egypt and Tobago. He gets his hands on over 100 new sails and boards every year as his company car. Privately, he prefers to surf with a foil on Lake Walchensee or “unfortunately far too rarely” in the waves. SUP is Stephan's second passion, which he pursued for several years at numerous SUP races. Today, he prefers to paddle on river tours with family or friends - even for several days.
