In very heavy air, when the boat is overpowered and twist increases, which adjustment reduces twist?

Twist control and sail shape are all about how the wind loads are distributed along the mainsail. In heavy air, the top of the mainsail can start to work too hard and twist off, which hurts power and balance. The boom vang is a key tool for managing that twist because it applies a downward force on the boom, helping to flatten the sail and keep the upper part of the mainsail from twisting too much. Loosening the boom vang releases some of that downward pull. With less downward force, the sail’s shape can shift so that the twist at the head is reduced, helping to depower and balance the boat in very gusty, overpowered conditions. In this scenario, this adjustment is used to calm the sail’s twist and maintain steadier flow across the mast. Other adjustments (like tightening the vang, adjusting halyards, or moving leads) affect different aspects of sail shape or balance and may not reduce twist in the same way.
