Why was Britain unable to defeat the French Navy during the American Revolution?

The British would dominate the seas during the French Revolution only a couple decades later (I'm looking at you, Lord Nelson), and as far as I'm aware, they did pretty good against the French during the Seven Years War as well. So, why were they for the most part (or at least when it counted) unable to defeat admirals like d'Estaing and de Grasse?
