Seemed quite easy after the Iowa!

Second is the ship as she appeared in 1939 with Measure 3, the Light Gray 5-L system (usually known as "Pre-War Light Gray".

The ship received various refits throughout the war and I plan to draw the 1942 refit, and possibly the 1945 Wichita if sources and time permit.

No new parts this time, sorry.

Both look very good, though, one eensee teensee criticism, if I may: the break where the flukes begin at the transom, should be more accentuated. Right now it looks like only a random line without purpose, I'm afraid. This line also should be more angled down, towards the bilge keel; in effect touching the outer shaft bipod stand. Other than that, I am suitably impressed. If you want, I can redraw those flukes, if you don't have time or interest and send it to you, I don't mind. 8-) :)

Knock yourself out -- if it's so important to you I don't see why you shouldn't be the one drawing it. :P

Another great cruiser by Colo. What is that 'thing' above the propeller, what's that for?

Clonecommander, what you're referring to is a unique design feature of the USN: a practice of theirs to design a flat, 'V'-shaped bottom floor with a Knuckle or break that usually began just below the CWL and extending in a gentle slope from the stern towards the amidships, usually ending above the outer shaft tube. Most US cruiser classes from the Pensacola featured it and it was both a weight saving measure as well a sea keeping thing; tests in tanks had proved that it improved the hydrodynamic flow quite substantially but it was also more expensive to build. I hope this answers your question!

may I ask what you refer to with CWL? I have never heard that abbreviation in shipbuilding terminology IIRC. the only thing I could think of was center waterline, an part that does not exist..........

Construction Water Line (I think that's the translation anyway.)

is that the waterline as it ends up to be or is that the same as the DWL (design waterline) ?

I think it's the same, though I'm not 100% sure.
When it comes to having multiple redundant and often conflicting acronyms nothing beats marine engineering.
