DSnider, you state "As you know, any attempt to turn the sailboat around from downwind toward upwind in high winds, will absolutely capsize the sailboat."
Then you suggest "reduce the centerboard to 30% or less".
A Catalina 22 has a swing keel that should remain down and stay down to provide the righting moment to right the yacht in a roll or knockdown. In addition pulling the keel up shifts the keel aft increasing lee helm almost certainly preventing the yacht getting the bow into the wind.
Perhaps you have mistaken the boat for a 22 foot catamaran.
Best way to get a monohull running out of control to pointing into the wind is with the motor going, wait for a wave to pass and turn as quickly as possible hopefully between waves, it will all happen at planing speeds and either work or not (obvious). A very effective rudder is as valuable as a well ballasted keel when all else is scaring you.
