Ease the backstay, the forestay should almost flop. Tighten the backstay about halfway, measure the tension in the forestay and note it. Add measured ammounts of backstay tension logging the forestay tension each time. Tighten aft lowers to limit bend. At some point you may notice that the forestay is not getting tighter when you add backstay, this is because the hull is bending .
