  • Wind Strength 8-16 knots: Adjust Upper Shrouds by +1.5 turns, Intermediates by +0.75 turns, and Lower Shrouds by +0.5 turns. Loos Gauge readings: Upper Shrouds - 41, Intermediates - 17, Lower Shrouds - 0.
  • Wind Strength 17+ knots: Adjust Upper Shrouds by +2 turns, Intermediates by +0.75 turns, and Lower Shrouds by +0.5 turns. Loos Gauge readings: Upper Shrouds - 51, Intermediates - 22, Lower Shrouds - 5.

Key Recommendations
For optimal performance, adjust the rig tension according to the wind strength, starting from the base setting for 0-7 knots and increasing tension as wind strength increases. This ensures the sailboat is properly rigged for varying conditions.
