USS Congress-- Part 4: A Special Kind of Frigate


In 1785, Barbary pirates, mostly from Algiers in North Africa, began to seize American merchant ships in the Mediterranean.  In 1793 alone, eleven sere taken with their crews and cargoes held for ransom.    This caused the U.S. to pass the Naval Act of 1794. to provide funds for the construction of six frigates.  But in cost cutting, a clause was added that if a peace treaty was signed with Algiers that construction would be stopped.

Joshua Humphreys design was unusual for the time with a long keel and narrow beam and mounting heavy guns.The "ratings" or number of guns carried, was a bit of a misnomer as these frigates carried many different numbers of cannons.  The USS Congress was rated at 38 guns, but often carried as  many as 48.

The designs also gave these ships much heavier planking on their sides than was to be found on frigates at the time, meaning they could withstand broadsides better.  Humphreys design took into account that the U.S. Navy could not stand toe-to-toe with the European powers at the time, but could do well against other frigates.  They could, though, escape from the more powerful but slower ships of the line.
