Brunel would need to balance durability with fleet numbers

What would Isambard Kingdom Brunel build if he became the Royal Navy's Director of Naval Construction in 1850?

He might initially overbuild, but his railway practice suggests he could delegate to naval specialists and establish a durable standard design that the fleet could procure in useful numbers.

Brunel's civil works were built for longevity and infrequent maintenance, qualities that become liabilities if every warship is so elaborate that the navy can afford only a few. His first instinct might be to concentrate too much fighting power into one enormous hull. His railway career supplies the counterweight: after recognizing that locomotive selection was not his strength, he delegated to specialists and adopted designs that could be procured in numbers. As Director of Naval Construction, he might therefore use naval architects to define a repeatable standard instead of personally determining every detail. Fleet construction rewards reliable series production and expert delegation alongside ambitious engineering.
