Claim:
A floating rowing machine to be used in a body of water comprising: A) first and second elongated floating members each having front and rear ends, and first and second lateral sides; B) frame means mounted to said first and second floating members; C) a seat assembly mounted to said frame means; D) paddle means having an axle rotatably mounted to said frame means and extending transversally across and beyond said floating members, said axle having first and second ends and a first sprocket member mounted to said axle at a predetermined position, and said paddle means further includes first and second paddle wheel assemblies rigidly mounted to said first and second ends and said first and second paddle wheel assemblies include a plurality of radially extending shafts each having a first distal end and further including a corresponding plurality of paddle members mounted thereon, respectively; E) a propulsion mechanism that includes a bar pivotally mounted to said frame means, and further including a coaxially extending actuating frame assembly having a second distal end that moves reciprocally between two extreme positions, said propulsion mechanism further including first linkage member for transmitting said reciprocal movement having third and fourth ends, said third end being pivotally connected to said second distal end, and a second sprocket member rotatably mounted at a predetermined location on said frame means remote from said second distal end, said fourth end being pivotally mounted to an off-centered point on said second sprocket member so that said reciprocal movement is translated into a rotational movement of said second sprocket member, and further including a chain assembly trained over said first and second sprocket member to transmit said rotational movement from said second sprocket member to said first sprocket member, axle and paddle wheels; and F) means for steering said machine including a steering bar pivotally mounted to said frame means at a predetermined rear position, a rudder member mounted to said steering bar following its rotational movement and second linkage member connecting said steering bar to said rudder for steering said floating machine upon the actuation of said steering bar.
