How did line-of-battle tactics differ from galley warfare tactics?

Line-of-battle tactics and galley warfare represent two distinct eras of naval combat, differing primarily in their tactical formations, primary weapons, and methods of engagement.

Galley Warfare

Galley warfare, dominant in antiquity and the Mediterranean until the mid-17th century, relied on oar-driven vessels. Because these ships were relatively unseaworthy and required speed for ramming, they typically employed a line abreast formation, allowing ships to approach head-on without obstructing one another. The primary tactics included:1
* Ramming: Using a bow-mounted ram to disable enemy hulls.21
* Boarding: Utilizing grappling hooks or boarding planks (such as the corvus) to facilitate hand-to-hand combat with soldiers.1
* Melee: Battles often devolved into chaotic, close-quarters fighting similar to land warfare, where individual ships sought out opponents for single combat.31

Line-of-Battle Tactics

Developed in the mid-17th century, line-of-battle tactics utilized sailing ships armed with heavy broadside cannons. This approach shifted the focus from individual ship-to-ship combat to fleet-wide coordination:34
* Line Ahead: Ships sailed in a single column, one behind the other, to maximize the firing power of their broadside guns without obstruction.345
* Command and Control: The formation allowed an admiral to maintain cohesion and control over the fleet, even amidst the smoke of battle.35
* Decisive Firepower: Unlike the melee of galley warfare, these engagements focused on bringing superior firepower to bear, often by "breaking the line" to overwhelm specific enemy vessels.4
