Broadsides and Boarding Parties is a board game created by Milton Bradley in 1984 as part of their Gamemaster Series. The only game of that series to feature a 2 player game (all of the games in the Gamemaster Series were for 2 or more players), Broadsides and Boarding Parties is a duel between a Spanish galleon and a pirate ship. Players take turns moving their ship and firing at the other ship to sink her. If the ships collide then players may take boarding parties onto the other ship to try to win.

Broadsides and Boarding Parties was discontinued several years after its introduction. It is highly prized amongst board game collectors.
