- at least two transverse members adjustably attached to the frame, having opposing ends extending away from the longitudinal axis of the frame;
- a first floatation member attached to one of the opposing ends of the transverse members;
- a second floatation member attached to the other opposing ends of the transverse members;
- at least one adjustable attachment means comprising a support arm and a crossbar, wherein the crossbar defines a channel that is closely received by the frame and the support arm has a first end that is closely received between the rail members of the frame, wherein the crossbar is removably attached to the first end of the support arm;
- a propeller drive assembly attached to the second end of the support arm of the attachment means;
- a rudder attached to the frame;
- and
- a crank mechanism adjustably mounted on the frame.
