They both "depower" the main but it's not the same thing going on: As the wind builds it pushes the max draft in the main aft. This increases drag until it slows the boat and increases heel. The Cunningham brings the max. draft forward again to make the aerofoil more effective. It increases lift and reduces drag. Making more of the lift available in the forward vector. It's more effective than tensioning the main halliard as the main halliard also tensions the leech, cupping it and reducing speed by increasing drag again. The Cunningham, mostly tensions just the luff. The baby stay will just flatten the main to reduce lift by increasing the cord lenth of the aerofoil (as far as it can bend our thick masts) As said before, it also stops the mast pumping, which the Cunningham obviously doesn't. You need both!

Both depower the main.... Does the adjustable baby stay (mast bend) make the Cunningham (luff tension) redundant? I have an adjustable baby stay, is adding a Cunningham a waste of time?
