Dock limits were part of a wider infrastructure problem. Before the First World War, the Royal Navy invested on roughly six-year cycles, but the conflict prevented a major round planned for 1916. The next point in that cycle would have been about 1922. Suez imposed a draft constraint that could also be addressed through dredging. The discussion treats these limits as constraints that infrastructure investment could change.
