67th Tigers

That depends. The War of 1812 showed that some embarrassing losses can be inflicted if the RN spreads its ships too thinly. 67th thinks that the superfrigate paradigm adopted by the US in the early 19th century (if you can't afford ships of the line, at least make frigates that can beat anyone else's frigates) was outdated by now, but a well trained US crew could probably give as good as they got providing they didn't run into a combined RN force that outnumbered them.
Not outdated, the Americans moved to a doctrine before the technology allowed. Lambert discusses it:

I've no doubt some 1 on 1 victories can be achieved, particularly if some of the USS Hartford gets out (she's a damn good ship, fast and well armed) and some others. We're (unfortunately?) past the age where privateering is viable, they need to be half decent warships, and Hartford is far more powerful than Alabama was (she makes 13kts and has a throwweight of 274 lbs, completely outclassing Hatteras (8 kts, 74 lbs, Alabama threw 5 times the metal in each broadside and was much faster, no contest), while the larger Kearsarge (11 kts, 366 lbs throwweight and heavier construction) was roughly evenly matched against her).
Hartford would be roughly evenly matched against a 40 gunner, as are most of the heavier frigates. The Merrimacks throwing 0.7 tons of metal per broadside. The 4 Merrimacks have throwweights more akin to small liners and might be able to win a duel with a liner (probably 60/40 in the Brits favour), and have very quite good odds against a larger RN frigate (a 51 or 1 of the 6 "Walkers" - Mersey, Orlando, Diadem, Doris, Ariadne and Galaeta, all built in the late 1850's specifically to counter the Merrimacks, and all 6 are in American waters). Whether they'd face single liners in duels....
