The Bucentaure class ships of the line were a class of twenty-one 80-gun third rates, designed for French Navy by Jacques-Noel Sane. These powerful ships had a designed crew of around 500, and they were armed with 30 36-Pounder guns in the lowerdeck, 32 24-Pounder guns in the upperdeck, 18 12-Pounder guns in the quarterdeck.

Neptune was launched at the beginning of the Napoleonic Wars. After missions on the West Indies, she was used against the British in Mediterranean Sea. During the Battle of Trafalgar she was engaged by Nelson himself, and she dueled with several British ships, surviving the battle. She later became part of the Spanish fleet, named Neptuno, after Spain declared war to France, and spent most of her life under the Spanish flag.

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 French Bucentaure class ship of the line "Ville de Varsovie 1808."
