It was a lot of fun and a great experience
It starts with a bit of theory and then we go straight into the water (without a sail at first) to practice standing on the board. Then we go back to the water to practice. While it sounds simple in theory and works great as a dry run, it's not so easy in the water. But if you stick with it (and stay on it), you'll manage. It's a lot of fun, and our children loved it too, and would have liked to go longer. One hour is perfectly adequate for a trial run and is suitable for absolute beginners. The instructor was very nice, motivating, and explained things well.
Perfect for getting a taste of windsurfing. An hour isn't too short either, as it's pretty strenuous. Great activity if swimming gets too monotonous.
