ABSTRACT:
A new and improved leg assisted forward facing rowing system is disclosed wherein a rower applies leg power to propel a boat by means of a rope connected between his or her foot and an oar. A unique feature is a roller, fastened under the heel of the rower's foot, that rolls along the bottom of the boat supporting the weight of the rower's leg while the reciprocating motion of the leg is transmitted by rope going through pulleys to reverse the force applied to the oar. The oar is pivoted at the center of the boat above the rower's knees by a mechanism that includes provision for applying lifting force to support the oar weight thereby holding the oar blade out of the water when no force is applied. The rower's legs, back and arms simultaneously apply rowing force. Feathering at the end of a stroke and squaring action at the beginning are provided by wrist action to rotate the oar blade. Ergonomically good features of a conventional sliding seat racing scull rowing are thereby incorporated into a forward facing rowing apparatus.
