There are several types of conditions that are obstacles to sending the kite sail into the air.
First of all, there are certain weather conditions that prevent the kite from being launched: if it is too windy or the sea state does not allow for easy manoeuvring of the boat; but also if there is not enough wind. In addition, the boat’s speed (the angle of the boat in relation to the wind) must also be taken into account when launching the kite, depending on the drift, the apparent wind must be greater than 10 knots.
