lateral twists in the dagger cases would be bad but if others are snapping 5.2 boards in heavy air it seems to me they don't give enough

those long high aspect daggers on boats like the inter17 and A cats at half the width and twice the length must bend more than 5.2 boards

if 2 daggers weigh 10kg, 22lbs, together, then the 2 rudder blades probably weigh another 5kg, 11lbs. that's 10% of the boats 150kg, 325lbs
