The Clyde had built ships for centuries, but steam power and nineteenth-century heavy industry turned it into a dense industrial system. Denny's alone built more than 1,500 ships between 1844 and 1963 across the eras of wood, iron, steel, and riveting. Slower construction methods and even horse-drawn delivery of components make that output especially striking. Long success then encouraged postwar reluctance to change processes while newer rivals modernized. The decline involved an institutional failure to renew productive methods while the old ones still appeared to work, rather than a simple loss of skill.
