General course information

Why are certain designs faster than others? How can I improve the performance of my yacht? How do I assess the qualities of a yacht from its basic data? Register for this course and learn sailing theory and the basic principles of yacht design. The course is taught at the common yachtsman‘s level. No technical education required!
