How did the line-of-battle formation allow sailing fleets to use their broadsides?

The line-of-battle formation, or "line ahead," was a tactical arrangement where ships sailed in a column, each following the wake of the ship in front of it. This formation allowed fleets to maximize the effectiveness of their broadsides—the simultaneous discharge of all guns mounted along one side of a ship—by ensuring that each vessel’s armament could face the enemy line without obstruction from friendly ships.12

By maintaining this column, the fleet functioned as a cohesive unit under the admiral's control, allowing for coordinated maneuvers and the concentration of firepower. Because naval guns of the era were only effective at short ranges, the line-of-battle enabled fleets to present a continuous, miles-long "ribbon of death" to the enemy. This formation marked a significant shift from earlier galley warfare, moving away from individual ship-to-ship combat—such as ramming and boarding—toward a strategy centered on the disciplined use of heavy, broadside-mounted artillery.123
