distances with a minimum effort according to another characteristic of the invention the kayak hull forms behind the seat a hold which can be accessed through an upper opening that is closed by means of a cover this opening can have fixed in the perimeter thereof a profile for example of a plastic material on which the cover is adjusted said cover made preferably from an elastically deformable plastic material according to another characteristic of the invention the hull forms at the top part thereof in front of the seat a recessed area being longitudinally crossed by an intermediate double wall separation which projects upwardly with respect to the hull surface the pedals are mounted on this intermediate separation the double wall passing through the axis thereof and said axis featuring a pinion being solidly fixed thereto that is located between the two walls of the intermediate separation the propeller is associated to the pinion through a transmission mounted underneath the hull in a position being retracted with respect to that of the pinion in order to achieve the maximum stability of the craft the kayak hull of the invention makes up at the lower part thereof a trilobular cross section having a main central body and two auxiliary side bodies.
