- Bodyboarding is based on a principle similar to that of surfing: the "bodyboarder”, that is to say the bodyboarder, is generally lying on his board, resting on the elbows with his bust raised and his hands placed on the nose of the board. When sliding on a wave, the bodyboarder remains in a lying position. Nevertheless, sometimes the bodyboarder, adventurous, is sitting or even standing.
- wakeboarding is a sliding sport requiring the use of a board.
- the athlete or commonly called “rider”
- the “rider” is towed by a boat using a rope with a rudder.
- a wave is created by the wake of said boat, the "rider” takes advantage of said wave to jump on both sides of said wake and perform different figures, such as, as non-limiting examples, somersaults, rotations and “grabs", figures inspired by "classic” sliding sports, such as surfing or snowboarding.
- the "rider” uses a board, ensuring good lift; on this board are fixed two feet for the feet in the direction of the length as for a snowboard.
- the choice of the board is determined by the style of the "rider”.
- this discipline allows to overcome the constraint of place, it raises other disadvantages: the position that the "rider” adopts on the board is sometimes not optimal because it can lead to pain problems knees and / or back and fast fatigue.
- the means necessary for the practice of wakeboarding are not very accessible. Indeed, the wakeboard requires the presence of a specific boat, specially adapted to the practice of this sport: besides the presence of a tower making it possible to fix the traction rope, such a boat is equipped with ballasts in order to be weighed down. as well as a specially studied hull, to finally obtain a wake generating higher waves.
- the boats are complicated to handle and require the presence of a knowledgeable professional, but also generates very significant costs because of their technicality.
- a motorized surfboard as described in US 6,192,817 B1 comprises a body in the form of a board defining a stern and a bow, within which is housed an internal combustion engine, closer to the stern than from the bow.
