Who We Are

We are two sailors from Germany, both passionate about boats and the technical systems on board. We ​started YachtKnowHow to help other boaters and sailors to keep their boats safe and ​provide them a ressource ​for advice and ​support. The information on this website is based on the extensive library of more than 1,800 pages of expert knowledge that Michael has created during his career of ​32 years as a technical writer. 

We are in the process of translating the content into English in order to make this wealth of information available to everyone.
