Nelson, Rodney, and the battle-line bulwark analogy

Winston Churchill's description of Nelson and Rodney as near-unsinkable battle-line bulwarks supplies a later analogy for the first rate's role. The interwar comparison was imperfect. A war against the United States rewarded British dispersion because the American battle line was slower, while a conflict with Japan demanded speed and maneuver in waters such as the South China Sea. Wooden first rates came closer to the image because buoyant hulls combined substantial survivability with concentrated firepower. Their three gun decks also gave admirals height and visibility, although the form demanded careful length-to-beam proportions and stability.
