Watercraft with manual propulsion system

A method of powering a watercraft with a deck, at least one hull, a bow, and a stern by the actions of an operator of the watercraft comprising the person utilizing a cross country ski simulator as a propulsion system, the simulator for use by the operator operating the watercraft, the simulator comprising:

• a) four parallel essentially horizontal tracks mounted on the deck of the watercraft wherein there are two inner tracks and two outer tracks wherein each of the inner two tracks are adapted with a foot receiving plate for receiving a foot of the operator and each of the two outer tracks are adapted with a pole receiving plate for receiving a cross country ski pole held by the operator of the watercraft such that the foot receiving plate and the pole receiving plates move in a bow to stern and back direction simulating a manual cross country ski motion by the operator;
• and
• b) four paddle blades each having a front face, a back face, and sides wherein one blade is attached to pole and each foot receiving plate in a manner that positions the blades below the hull of the watercraft such that the paddle blade moves bow to stern and back as each of the pole or foot plates move bow to stern and back by virtue of the manual application of forces by the hands and feet of the operator of the watercraft in a manner such that each blade is manually operated independently of the other three blades, wherein when a blade is moving bow to stern and stern to bow, the blade back face presents a greater surface area perpendicular to the direction of travel in one direction than the blade front face does when the blade is moving in the opposite direction by manual application of force by the hands or feet which folds the blade around a fulcrum hinge to a position parallel to the direction of travel.
