After a more detailed explanation (perhaps the time we spent in the classroom could be reduced and part of the "agenda" to see it directly on the boat) of the documentation that had been sent to us a couple of days before by email (this gave us time to read it and that everything sounded to us), we went to the boat to practice what we had seen theoretically.
Good atmosphere generated by the instructor (Queco), who explained in a simple and enjoyable way each maneuver to perform, and why. Very well also with the rest of the participants.
A pity that there was little wind and we were wanting more.
A good experience that I will certainly repeat!
