What the early US Navy could add to the Second Coalition

What could the United States contribute if it joined the Second Coalition in 1800 instead of making peace with France?

A few frigates and useful anti-privateer work, plus morale support, but not enough naval power to transform the war.

The counterfactual begins just after the young US Navy's Quasi-War experience. The American contribution would first provide valuable morale support. Its few frigates could help suppress French privateers in the western Atlantic and Mediterranean. They were not numerous enough to alter the coalition's main naval balance or carry a much larger strategic burden.
