When CSS Nashville was surrendered at Nanna Hubba Bluff she was described as being hogged athwartships. That is ambiguous. does it mean the paddleboxes were out of true vertically, or does it mean, as is sometimes depicted that there was a horizontal truss between the boxes at the top? I tend towards the latter as the same device was commonly used on large seagoing paddle steamers, often used to support light bridgework. Bil R more or less confirms that as he says above.Hi John, Nashville has always been described as not strong enough to be fully ironed. I've never seen paddle box supports depicted like this. I'm wondering if the fore and aft timbers might also function as hogging trusses? The projection from the bow may be an attempt to depict a spar torpedo deployed.
I really do not know what to make of that very strange alleged portrayal of Nashville . To me it appears to be more than one vessel run together, one end being different to the other. The tent shaped framework could be exactly that.
The Nashville plans Bil referred to were apparently the constructors drawings, not Porter's original, and were stolen along with a lot of other stuff. This is very common in the riaroad world
