I lived in Hamburg for a year and during the summer a friend and I decided that we wanted to take…read moreup sailing. Given that I am a native English speaker and still consider my German to be so-so, I was a bit apprehensive about signing up for a sailing course since the end-goal is obviously to pass both the written and practical exam to receive one's sailing license. Needless to say, my convinced me to give it a shot and I'm glad that I did. The Prusse staff was extremely accommodating and would explain things in English if I was a bit uncertain about the German explanation.
In the end, I passed both the practical and written exam and now am a proud holder of a sailing license in Germany. Almost nobody fails the practical exam as it's recommended that you complete 40 hours of sailing before taking the exam, but quite a few people do not pass the written exam. My words of advice- buy the book that Prusse offers! After spending so much on the sailing course, don't skimp out on buying the textbook for an additional 30 euro. It's completely necessary! They changed the format of the exam to all multiple choice, which I was beyond excited about. You're notified right after taking the exam if you've passed or failed.
