Fleet concentration rather than one-on-one duels

The discussion rejects treating warships as isolated competitors in a duel. The Royal Navy is described as designing a fleet to concentrate several ships against one opponent, including under treaty constraints. That approach favours balanced, survivable ships that can be repaired and returned to the line instead of making every hull individually superior in a notional duel. One-to-one specification comparisons can mislead because expected fleet employment shaped the design.
