Let’s look at the causes of these injuries.
           A great part of the injuries (45%) is caused by the ocean bottom: we generally touch the bottom after a fall and when we are swept along by a wave (during a unsuccessful duck dive, for example).
           The second cause of injury is one’s own board (10% of the injuries). Beeing hurt by the board of an other person is only the cause of 3% of the injuries. The bodyboarders are luckier on this point than the surfers: 55% of the injuries of the surfers are provoked by a collision with one’s own board and more than 11% by a collision with the board of another surfer. This is mostly due to the difference between the types of material that are employed in both cases : bodyboards are made of foams, which is dense but which hurts less easily than a bulkier surf.
           The wave in 10% of the cases, then the leash, in 9%, follow: the leash remains a dangerous element of the bodyboard because it can coil around the bodyboarder in case of fall.
           It can be noticed that there is still the 3% of injuries provoked by sea animals.

           Concerning the circumstances, we are going to study successively the types and the height of the waves, and then what the bodyboarder’s doing when he hurts himself (what trick,...).

           First, let’s look at the type of wave. We find in majority beachbreaks (at 56%) and then reef waves (at 28%). This result could seem at first sight a little bit strange, but it can be easily explained: beachbreaks are more surfed than reef waves, it is so quite normal that more accidents occur there. However, if we consider the ratio between the number of accidents and the number of surfed waves, we will find that the reef is far more dangerous than the beachbreaks.
