WIND RANGE
6
The wind ranges are expressed in knots and the sizes in actual square meters.
This wind range is given to you as an indication for a rider weighting 75 kilos. Wind range varies
according to each rider. It depends on:
The rider’s level: the more you progress the more you will be able to use the kite in the upper
wind range.
The rider’s weight: the bigger you are the more you will be able to use the kite in the upper
wind range.
The board’s volume: the more volume your board has the more you will be able to use the
kite in the lower wind range.
You also must choose your kite according to: the aerological situation (the airflow quality), the
weather conditions (wind direction, speed, forecast), and the overall quality of the spot and the level
of safety it offers.
When you get to the spot, measure up the wind speed. Take your time to figure out the conditions,
don’t make any mistake, one minute is not enough, you need to control that the wind is steady free
of gusts. Check out the other kites, their sizes, that will give you some indications on the conditions.
If you hesitate between two kite sizes always take the smaller one, you will have more fun riding
underpowered rather than overpowered.
If you cannot walk backward alone with the kite in the air, that means that you are
overpowered. Land your kite.
