The Inflexible-class ships of the line were a group of four 64-gun third rates, designed for the Royal Navy by Sir Thomas Slade, based on his earlier design for the Albion class. These ships had a designed crew of around 500, and they were armed with 26 24-Pounder guns in the gundeck, 26 18-Pounder guns in the upperdeck, 10 4- pounder guns in the quarterdeck, and 2 9-Pounder guns in the forecastle.

HMS Polyphemus was laid down at Sheerness in 1782 and commissioned in 1799 under the command of Captain G. Lumsdaine. She sailed in the North Sea Fleet on the Baltic Sea until 1802. In 1805, Capt. Robert Redmill commanded her in the Battle of Trafalgar, where she engaged the French ships Neptune and Achille and captured the Spanish ship Argonauta. She was later in service along the French coast and in the Americas.

The ship base, ship card and ship log are printed on two sides - the game data of a second ship is printed on the back. This ship pack can also be used to represent the British Intrepid class ship of the line "HMS America 1777".
