A good experience to go by boat with a large sailing area. Necessary experience to know what sailing is. The only thing I notice missing would be a notebook or notes to remember in the navigation so that it is not forgotten. Remember direction of propeller rotation, lights that we are going to find, both ours and agenas. Theoretical course plotting. That is, a kind of practice / trip booklet to be filled in by the student voluntarily. For the rest of what has been said, you must experience sailing and see the expressions of the sea on the boat.
