Set of pieces in kit form for the quick assembly of boats, optionally propelled by pedals and paddlewheels, configurable for one or some passengers, constituted by a basic structure with several crossbars placed traversely in relation to the direction of advance of the boat, that are secured to at least two main longitudinal floats whose number is equal to the number of passengers plus one. All the necessary elements for propulsion and control of the pedal boat and for passenger's accommodation are placed between each two adjacent floats. The basic structure previously cited gets rigidity with two longitudinal bars or plates that ends in two traverse segments each one. The longitudinal section of these longitudinal bars or plates is secured to the traverse crossbars of the boat and their respective traverse sections are fixed to one of the floats. The propulsion and control elements of the boat can be joined and assembled side by side serially in a number equal to the number of passengers of the boat. |
