I didn't notice it being mentioned yet, but one of the reasons I do not like wings for racing is that most beach-cats require you to get your weight far forward in light air to keep the sterns from dragging. Wings add weight to the aft half of the boat, making it even more difficult to keep the transoms out of the water.

And compounding the difficulty of getting weight forward is that you have to climb over the bar supporting the wing in order to get forward on the hull.

Unfortunately, most sailors in the United States do most of their summer racing in light-to-moderate wind conditions requiring a lot of fore-and-aft weight distribution movement. It's really tough to do with wings.
