The present invention relates to a boat propelled by two submerged independent wings actuated by means of a step simulator mechanism that imparts an vertical alternating movement to the wings, which are articulated around a shaft located forward of the center of pressure thereof, such that the wings assume angles of inclination that generates propulsive force in the upward and downward movements. In the analogous position of a conventional bicycle, the driver actuates the footrests while seated. A handlebar, connected to a rudder, is used to maneuver the vehicle. The catamaran configuration offers hydrodynamic efficiency and stability. When disassembled, the mainframe of the boat can be converted into a step machine, simply fitting a pair of dampers to the structure, which absorb and dissipate the energy generated during exercising. Thus, the present invention has a dual use—boat and gymnastics apparatus—and can be transported in the car trunk.
Boat that can be converted into a gymnastics apparatus characterized by having a mainframe (1) on whose sides are mounted in an articulated manner, the sidebars (2) and (3), and in an intermediate position thereof is fixed the footrest (4) and in a rear position is fixed a propulsive rod (5), at the end of which is fixed a fin of flexible material or mounted a wing (6), which serve for propulsion, and a string (7) binds the sidebars (2) and (3), passing through the pulley (8) and four connecting bars (9) connect the mainframe (1) with the floats (10) which can be rigid or inflatable, and in the front of the mainframe (1) is mounted the steering tube (11) whose lower end is fixed rudder (12) and at the upper end of the steering shaft (11) is fixed a handlebar (13), which is thus linked to the rudder (12), allowing a driver to maneuver the boat while may be sitting on a seat (14) which is fixed to the mainframe (1).
