ABSTRACT:
A floating exercise rowing machine with two elongated floating assemblies that are kept at a parallel and spaced apart relationship with respect to each other by two transversal frame assemblies and a longitudinally extending frame assembly. The frame assemblies support a seat assembly mounted at the middle of the floating exercise machine. A propulsion mechanism that includes a bar that is pivotally mounted to the frame assembly with a coaxially extending actuating end that moves reciprocally between two extreme positions to cause, through linkage arms, the rotation of sprockets that in turn impart a rotational movement to a transversal axle that supports two paddle wheels at the ends. A steering mechanism permits a user to steer the floating machine with his/her hands.
