Thanks for those lines, that book is on my list to purchase.
Unfortunately, those lines are quite different from the Nenana.

I'm having some trouble modeling the bow, as it is quite unconventional.
I believe that this was due to her very shallow draft.
If you look at other similar ships from the same region and time period,
you see a more typical bow profile, like that shown in Western River Steamboats.
For example: SS Klondike (found on the internet, removed by request if needed)

(On second thought, I wonder if you simply scaled the lines Barry uploaded by 50% vertically?)
