An oblique slider guide lets rowers adjust oar shaft angle precisely on the boat without time-consuming sleeve machining.
A rowing apparatus grip lever actuates a coaxial actuator rod to rotate the oar lever.
Scissor-link gauges identify the center point between tracks, reducing friction and wear from misaligned wheels.
Pivot outriggers provide mechanical leverage for forward-facing rowing, resolving the trade-off between simple craft design and high propulsion efficiency.
