Getting closer to the sea and sailing means discovering a completely different world where there are rules, strange terms, different habits. What we do on land without difficulty and without thought sometimes requires special attention when on board a boat. Even just walking forward can be a new experience. The elements, which we often close outside the door or window of the house, here knock on our door and ask to be listened to, understood, experienced. The air is different, the light is different, the immense spaces in front of us are different. The people who operate these floating islands use terms that are incomprehensible to us, which often indicate objects with a strange appearance and a mysterious function. Let's discover here, in this section of the site, some of the mysteries and charms of navigation.
