Why the sail-to-steam transition was harder than it looks

Decisions about paddles, propellers, ship design, and support were being made while the technology was still uncertain. The familiar late examples were mature third-generation products built on earlier trial and error, just before ironclads displaced them. Looking backwards can make the outcome appear inevitable, but contemporaries had to create the infrastructure and operating knowledge that made steam fleets viable. Advocates seeking money for ironclads also had an incentive to disparage the outgoing steam rates, so later dismissals must be read in their procurement context. The closing passage gathers the video’s argument about technological transition and the systems required to sustain it.
