Test & Technology editor

Hauke Schmidt was born in Hanau, Hesse, in 1974, but moved to the coast at the age of an Opti and grew up sailing dinghies and tall ships. School and semester breaks were used for extensive Baltic Sea cruises. During and after his oceanography studies in Kiel, he took part in various international research trips to tropical and polar regions. The focus was on ocean currents and their influence on climate change. Eventually he was drawn back to his home coast and to YACHT. He completed a traineeship there and has been working as an editor in the Test & Technology department since 2009. His core tasks include equipment and boat testing, as well as practical topics relating to electronics, seamanship and refits. As a passionate DIY enthusiast, he loves to spend his summers on the water with his family and winters working on his boat
