Royal Navy infrastructure supported expansion in the 1840s

If more age-of-sail ships and screw repeats were completed in the 1840s, how much better off would the Royal Navy be?

It would be better off, but from an already dominant position; Britain's real advantage was the infrastructure and spending base that let naval capacity compound.

Finishing more sailing ships and repeating screw-propelled designs would strengthen the Royal Navy in the 1840s. Britain already held a large advantage in ship numbers and naval infrastructure spending while continental rivals had to fund armies. Dock capacity grows with the fleet's maintenance schedule: in the illustrative one-in-three cycle, six ships require two suitable dry docks and twelve require four. The same reasoning leads into modern Britain's stock of older docks. The argument distinguishes docks that still exist from the smaller number maintained and invested in over recent decades. Restoring suitable dormant facilities could increase operational capacity without having to create every dock from scratch.
