Abstract:
1. A pedal powered craft comprising: a vessel having a forward end and an aft end joined by a port side and a starboard side with a longitudinal midline axis extending between the forward end and the aft end; a paddle structure attached to the vessel and capable of pivoting about a vertical axis that passes through the midline axis such that a paddle blade of the paddle structure is capable of radially swishing back and forth on either side of the midline axis; a port pedal structure attached to the vessel on the port of the midline axis and capable of reciprocating back and forth toward the forward end and the aft end; a starboard pedal structure attached on the starboard of the midline axis and having a starboard pedal capable of reciprocating back and forth toward the forward end and the aft end, such that both the port pedal structure and the starboard pedal structure are equidistant to the midline axis on their respective side and such that when the port pedal of the port pedal structure and the starboard pedal of the starboard pedal structure are each aligned with one another, they are located equidistant from the forward end; a first cable having a first end attached to the port pedal structure and a second end attached to the paddle structure to the port of the vertical axis; a second cable having a third end attached to the starboard pedal structure and a fourth end attached to the paddle structure to the starboard of the vertical axis; a pulley located on the midline axis and forward of the port pedal structure and the starboard pedal structure; a third cable having a fifth end attached to the port pedal structure and a sixth end attached to the starboard pedal structure such that the third cable passes over the pulley; and wherein whenever the port pedal and the starboard pedal are aligned, the paddle blade is located on the midline axis and such that as the port pedal and the starboard pedal are each reciprocated back and forth in opposing direction to one another, the paddle blade swishes back and forth.
