I used the wild thing solo on my Nacra 5.2 to great success on my last race. I had about 1Km when I turned downwind to catch a 5.8 and was not gaining substantially with me on the windward side. Straddling the tramp center bar I was able to stay in control by shifting my weight (apart from from a couple of sharp turns and emergency mainsheet releases which must have looked scary from shore). It wasn't exactly "comfortable", but who cares, I was racing and obviously catching up twice as fast as before! It was fun, more adrenaline that watching and waiting.
