Everything is a trade off, and this seems to be particularly true of sailing boats. Everything has been said here pretty much. Yep, you get your floor back, but it's nine feet high on a trailer. You can crank up a swinger off the shoals, but that Mickey Mouse hinging mechanism is "concerning", (although they seem to hold up, despite the smaller bolts).
But......if I had one that lived in the water most of its life, I'd probably run with the wing. It IS a shallower draft than the swing, and if you shoal it, well.......should have been reading those charts, or plotter. And before anybody starts screaming at me about grounding a boat, yes, I have done it too. Sail long enough, and MOST do. I builds character. Learn new tricks about kedging yourself off.
I however, have always been intrigued by the wing. In '83 at the A.C., the Aussies did hand Dennis his ass, but the majority of the blame should go to the N.Y.Y.C. But when Conner came back at 'em, (with a wing of his own), we all know the results. The fastest 12 meter in the world didn't do it on a fin, shoal, OR bulb keel. Now, there were a thousand other contributing factors to the '87 race as well, but the facts are, what they are.
