Question: What served Nelson as his flagship from 6 June 1799 until the end of June 1801, and was one of two British-built 80-gun ships he other being designed by Sir Edward Hunt?
Sentence (from "Fourth-rate"): While the number of guns stayed subsequently in the same range until 1817, after 1756 the ships of 50 guns and below were considered too weak to stand in the line of battle, although the remaining 60-gun ships were still classed as fit to be ships of the line.
Relevant evidence: No
