Frankly, the hull looks entirely too tall compared to all of the drawings I've seen of Keokuk. I collected a lot of drawings as I considered drawing Keokuk myself at one point.
By the way, I have a partially-complete New Ironsides if someone wants to finish her.
She is correct, but some drawings show the waterline was higher. I've I enlarge the red 3 pixel above it, they problem isn't.
