Como se puede apreciar según la descripción anterior el kayak de la presente invención permite combinar el kayak tradicional con pedales en una embarcación estable que alivié el trabajo realizado en largas jornadas de navegación o de pesca y que además permita seleccionar el nivel de asistencia del motor contribuyendo en la práctica deportiva de manera gradual para principiantes o niños. The seat (5) of the kayak is of adjustable position, for which it is arranged on longitudinal guides integral to the hull. As indicated above, the pedals (3) are mounted in front and above the surface of the seat (5), so that the actuation thereof can be carried out in a comfortable position of the occupant of the boat. As stated above, the kayak of the present invention operates in such a way that the pedaling can be assisted by an electric motor (4) but always requires physical pedaling by the user for proper operation. As can be seen from the previous description the kayak of the present invention allows combining the traditional kayak with pedals in a stable boat that relieved the work done in long days of navigation or fishing and also allows selecting the level of assistance of the engine contributing in sports practice gradually for beginners or children.
