Why the wooden wall is a specifically British metaphor

Could the French and Spanish navies be explained through their own versions of the wooden wall?

They deserve their own studies, but not under the same label: the wooden wall was a British metaphor, while France and Spain organized and understood naval power differently.

The wooden walls of England is a specifically British description of naval strength. Each additional warship could be imagined as another brick in that wall. The French and Spanish approached their fleets differently, so an equivalent study would need a different title and emphasis. An expeditionary-fleet description is suggested as more appropriate to their perspective.
