How to determine the right Olli?
To calculate the breaking force needed, use the formula:
Sail area (m²) × wind speed² (knots) × 0.021 = Working load (daN)* × 5 = Breaking load
*1 daN = 1.01971621 kg
Alternatively, quick formulas to estimate required breaking strength:
- Halyard or mainsheet breaking strength = Genoa area × 80
- Halyard or mainsheet breaking strength = Main sail area × 100
- Spinnaker halyard or mainsheet breaking strength = Spinnaker area × 30
