Battleships are enemies that appear in The Legend of Zelda: The Windwaker, and The Legend of Zelda: The Phantom Hourglass.
Battleships are metallic boats that are about as large as regular sailboats. They also carry flags on top of them.
Battleships fire cannons at their foes, but for some reason, they have trouble firing in close range. This was likely due to the cannons are more suit for long-range shots.
