The instructor´s calm approach created a positive atmosphere and a great sense of teamwork on board. Even though I had some sailing experience already, I learned a great deal about procedures under sail and safe manoeuvring in and out of harbour.

02 / 05
From the very first moment we were actively handling the boat ourselves. We left the dock, manoeuvred in harbour and sailed in realistic conditions. The learning truly stuck because we were constantly doing, not just observing.

03 / 05
This was not a course were you sit on the sidelines. We were active throughout-from from departing the dock, harbour manoeuvres to sailing upwind and downwind. By the end of the weekend I felt more confident handling the boat in harbour and sailing with all sails set.
