What is the basis for the thickness? If it is stiffer an stronger than the deck layup, it is wasted. Given the limits of the windlass, deck, and chain, I seriously doubt anything over 1/4-inch will have value to you, but some simple engineering calculations would tell. Additionally, bonding it to the deck will greatly decrease the required thickness, as the deck and plate will act as a unit. If the plate doesn't conform to the curve of deck, the load distribution is haphazard.

Really, the load on the windlass should not be great if a proper chain stopper is used. That is where the big snatch loads are.
