Whether beginner, amateur or experienced, this book still has something to offer you. The school is a mythical Glemans school referred to in the middle of the marina and had the privilege to see happen as students and instructors as the biggest names in sailing. It is not a simple course but a real transfer of experience and knowledge. Even if you do not plan to enroll in a training course on site, read it, keep on hand, come back to it between 2 trips, this work will always be a valuable companion.
