What was peacetime acquisition of third rates like in the age of sail?
Short answerIt was a continuous process of construction and great rebuilds, helped by frequent shifts between peace and war.
NotesFrequent wars encouraged steady dockyard work, but peacetime did not suspend construction and maintenance. Great rebuilds renewed existing third rates while new orders kept skills and facilities active. Work could involve one ship or a batch according to fleet condition rather than a single program separated from all later upkeep. The process was therefore closer to continuous fleet husbandry than today's sharply separated acquisition projects.
