This is the only steamboat I'm familiar with:

 

New Orleans' Only Steamboat | Steamboat NATCHEZ

The Str. Natchez was designed by the late marine architect Alan Bates(who just passed away a few years ago). He knew more about Mississippi River-type steamboats than anyone alive. Among other things, he saw to the refitting and refurbishment of the Belle of Louisville both after the city purchased it in 1964 and after it sank in 1997. I never got the chance to meet him, but when I first took an interest he was a regular contributor to a steamboat message board probably 10 or 12 years ago. He wrote a few definitive volumes-one on the Belle of Louisville specifically, and another general(and very technically heavy) one on steamboat design and history in general. I keep meaning to drive over to the Howard Steamboat museum and pickup copies of both.

With the Natchez, he set out to design both the most beautiful and authentic looking sternwheel steamboat of the modern era. I have to say that he successful. Also, interestingly enough, the first and long-time master of the Natchez was Capt. Doc Hawley. He has served as master of 3 of the 5 surviving paddlewheel steamboats-the Belle(under the name Avalon), the Delta Queen, and the Natchez. He's also the owner of the original Belle of Louisville Calliope--as I mentioned he bought it separately from the boat when it was sold.

The Natchez competed along side the Delta Queen and Belle of Louisville in the Kentucky Derby Steamboat Race exactly once, and left both of them in the dust. Since steamboat races have a long and storied tradition of unfair play, the organizers banned the Natchez from any further entry :) . (it's worth mentioning that Alan Bates was on record as saying that even the Belle of Louisville/Delta Queen races had lost any modicum of realism because the Belle had gained too much weight over the years to even be remotely competitive with the larger and more powerful DQ).
