Estimating the power of small-tube-boiler Agincourt

Could improved machinery provide enough power for a faster Agincourt?

An extrapolation from small-tube boilers paired with geared turbines suggests roughly 120,000 shaft horsepower, or about 110,000 conservatively. It remains an estimate, not a recovered trial result.

John Evans uses Malaya's trials to question how much extra power a faster Agincourt would need and suggests roughly 100,000 to 105,000 shaft horsepower together with a longer hull. An alternative estimate pairs small-tube boilers with geared turbines. Extrapolating from an 18-boiler installation rated around 90,000 shaft horsepower gives roughly 120,000 for 24 comparable boilers. About 110,000 is offered as a more conservative estimate. The calculation is approximate and depends on the assumed machinery, with hull length and refinement also affecting the proposed speed.
