A kayak having a cockpit containing a seat and a set of rotatable of pedals, the kayak propelled by a propeller, the propeller driven via a linkage by the set of rotatable pedals. Preferably, the rotatable pedals are mobile fore and aft substantially parallel to a center line of the kayak, and the drive shaft to the propeller is able to be extended and retracted to maintain the transmission of power and rotation from the rotatable pedals to the propeller. Also preferably, the cockpit containing the seat is molded into an upper deck of the kayak such that a hip of a user is substantially fully below the upper deck, and the cockpit has substantially no overhangs, such that, after capsizing and righting of the kayak in water, substantially no water is retained in the cockpit. The kayak also preferably includes a torque-tube steering system that permits a user to steer with either hand, and without interrupting the propulsion of the kayak on the water. The kayak also preferably includes a removable insert sized to fit a cargo hatch in an upper deck of the kayak, the insert also sized to seat a child or animal.
A monohull water craft comprising a kayak having a cockpit containing a seat located such that a hip of a user is substantially fully below an upper deck of said kayak, said cockpit also containing a set of rotatable pedals, said kayak propelled by a propeller that is driven via a linkage by said set of rotatable pedals, wherein said set of said rotatable pedals is mobile fore and aft substantially parallel to a center line of said kayak, and wherein said linkage includes a drive shaft leading to said propeller, said drive shaft able to be extended and retracted to maintain the transmission of power and rotation from said rotatable pedals to said propeller.
A monohull water craft comprising a kayak having a cockpit containing a seat located such that a hip of a user is substantially fully below an upper deck of said kayak, said cockpit also containing a set of rotatable pedals, said kayak propelled by a propeller that is driven via a linkage by said set of rotatable pedals, a stern of said kayak being truncated behind said seat substantially perpendicular to a center line extending along said kayak to provide a transom, wherein a drive shaft disposed between said rotatable pedals and said propeller is maintained inside said kayak until said drive shaft reaches a port in said transom, said port sized to fit said drive shaft, and wherein said propeller is maintained behind said transom.
