Abstract
Improvement to boat rowing in which the oars are upwardly biased, rotationally biased and forwardly biased to lift out of the water, rotate into the feathered position and swing to the front of the boat when at rest. A cord, attached to foot pedals, pulls the oars into the vertical position, down into the water and rearward in the water for the power stroke. Oars may be operated by hands only, by feet only or by hands and feet.
Claims10
An apparatus for use in rowing of a boat having forward facing oars of the type with oarlocks at the innermost ends, said apparatus comprising:
- a. an oar,
- b. an oarlock allowing pivotal movement of said oar upward and downward and forward and rearward,
- c. a means of upwardly biasing said oar such that said oar clears the water when at rest,
- d. a means of forwardly biasing said oar to a position approximately 30 to 60 degrees from dead ahead, whereby the oar, when at rest will be positioned ready to begin a power stroke.
An apparatus for use in rowing of a boat having forward facing oars of the type with oarlocks at the innermost ends, said apparatus comprising:
- a. an oar,
- b. an oarlock allowing pivotal movement of said oar upward and downward and forward and rearward,
- c. a means of rotating said oar about its longitudinal axis approximately 90 degrees for feathering and power delivery positions,
- d. a means of rotationally biasing said oar into the blade-horizontal or feathered position,
- e. a means of forwardly biasing said oar in a substantially horizontal plane such that said oar will be in a forward position approximately 30 to 60 degrees from the longitudinal centerline of the boat when at rest, whereby the oar, when at rest will be positioned ready to begin a power stroke.
