Default A question...Batwing hulls

Good friends of mine were very nice to give me lots of back issues of the Reflector a ways back, their way of enhancing my Steamboat Education.I've read them all, most twice, marvelous stuff.

The Reflectors mention from time to time that there were steamboats, principally made for low water conditions on the Ohio, pre-today's locks and the 9 foot channel, that had a "batwing" hull, specifically designed to allow the boat to travel in very shallow water conditions, 3 to 4 feet. I guess/envision that this batwing hull was actually the hull with your typical V in the center with two additionally smaller V's, one each underneth the looking at the hull lengthwise it would look like a double W, or in modern terms like a triple hull on a fiberglass runabout...These additional side "V's" would allow the same volume of hull to be submerged, creating the same bouyancy, but not nearly as deep as a conventional single V. Or am I all wet, overactive engineer's imagination...

So what's a batwing hull? And does anybody have a picture?
