The one thing I know about the deck camber is that the centerline peak on Scharnhorst is a straight line from the stern all the way to around the front breakwater. In other words if you look at the ship from the left or right side, you could draw a straight, horizontal line from the very tip of the stern to the centerline of the breakwater. Everything else slopes down from there to the edge. I don't know if the camber maintains a constant radius from front to back, in fact I kind of think it doesn't, but I don't know for sure. It took me quite a while to figure out the straight line thing but a lot of things fell into place once I stopped trying to make the centerline peak follow the curve of the deck edges. While doing the Scharnhorst, it took me about 2 to 2-1/2 months to finish the hull. I am doing another German subject and it took me maybe a week to do the hull, and I think the straight line fact is one of the major reasons it took such a short time. Of course I learned a lot about doing hulls so it is not the only thing, but I think it was definitely one of the bigger ones.
