How It Works

Calculate rowing oar gearing from inboard length and span (rigger spread). Leverage ratio = inboard divided by (total length minus inboard). FISA standard span: 158-163 cm for coxed boats

Each component has a specific meaning:

  • Inboard length — The inboard length recorded for the scenario being assessed.
  • Span — The span recorded for the scenario being assessed.

Note: Interpret the rowing oar inboard result against the thresholds and context described above.

How to Use

Enter the inboard length, span for the scenario you are assessing. Calculate rowing oar gearing from inboard length and span (rigger spread). Leverage ratio = inboard divided by (total length minus inboard). FISA standard span: 158-163 cm for coxed boats. Use the rowing oar inboard result to inform your calculation.
