Britain's capital-ship construction ceiling before 1914

What could a build-everything Royal Navy lay down from 1910 to 1913 if only shipyard capacity mattered?

Roughly nine capital ships per year, with trained shipyard labor rather than physical slips forming the hardest limit.

The estimate assumes that materials and money are available and asks what the yards could physically sustain. Britain laid down thirty-six capital ships between 1905 and 1914, including six for foreign customers, and reached nine starts in one year. Eleven yards and roughly twenty-one suitable slips support an estimate of nine annual starts while other shipbuilding continues. Expanding a workforce from 12,000 to 15,000 would allow a quarter of the experienced workers to train newcomers while most established teams continued working. Doubling a hundred-person workforce would disrupt every existing team, so a large industrial base could absorb growth more easily.
