I will take a stab at that.

Wings do and do not make the boat effectively wider. The crew weight out like on a wider boat but the weight of the hull and rigging is not. Plus you have the effect of the weight of leeward wing working against you. You also do not have the stability of a wider boat. Wings are more like, having a 2 foot taller crew than a wider boat

Don't get me wrong, I like wing boats. I think their advantage is getting your weight out in a safer and more secure way than trapping. For example, with the skipper planted securely on a wing, an 18 magnum will handle wave conditions nothing else will. A Wave with wings and that long promised Hooter would be fun too.
