I have never been too keen drawing that sort of stuff onto the hulls. I noticed their inclusion on the Friedman's drawing of Oregon City, so I might add it in a later revision. In my experience adding strakes in the hull line tends to end up cluttering the underwater hull, and when I tried to draw it on Oregon City, it interfered with the "look" of the boot-topping as well.
Anyway, if it's true that the Clevelands did not have it, then the Fargo would not have had it either as they were built on Cleveland hulls.
