This can be a result of insufficient wind, choosing a kite that is too small for the current wind, rigging incorrectly, having a kiteboard that is too small, the presence water current in the same direction as the wind, not riding fast enough, etc. A kitesurfer who is continuously diving the kite and sending it back up in a sine-wave pattern is usually underpowered.
