Richard Harding's fleet figures show the British maintaining a persistent advantage in fourth rates and smaller cruisers even when the balance in ships of the line was much closer. France and its allies fell from 144 such vessels in 1796 to about 90 in 1800, making five captures in one action a meaningful share of the remaining force. By 1805, Britain had 160 cruisers in service against 71 for France and its allies. These ships surveyed coasts, took soundings, carried dispatches, scouted, repeated signals, escorted convoys, protected fisheries, guarded ports, suppressed raiders, and supported exploration. Their lower replacement cost made them suitable for hazardous charting work that no admiral would casually assign to a ship of the line. British admirals still complained of frigate shortages despite possessing far more small warships than their opponents because demand for these everyday tasks was effectively unlimited.
