British cannon consistency and charts became strategic advantages

Did major age-of-sail navies have relative strengths in ship components other than timber?

Yes; Britain stood out for consistent cannon production and exceptionally valuable hydrographic charts.

French foundries could occasionally produce excellent cannon, but Britain achieved more consistent quality in volume. That consistency mattered because a fleet needed interchangeable expectations across many guns, ships, and yards rather than a few exceptional pieces. British chartmaking also benefited when Huguenot specialists fled France and joined an already capable surveying tradition. The resulting charts of French waters could be better than France's own and were prized as operational intelligence.
