This is a very clever device that was initially designed by a group of divers and was first presented in the Spanish Boat Show in Barcelona recently. It is available in four different models ((Jet Ski, Water Motorcycle, crafts up to 4m and 450kg and small powerboats). It weights around 150-175kg depending on the model and gets in motion via a petrol engine. It can not get into the water; it has a manual winch to pull the craft and the operator on the water by using elastic tubes. Its price ranges from 4.500-5000euros which generally does not make it affordable to everyone.
