Carracks fitted for war carried large-calibre guns aboard. Because of their higher freeboard and greater load-bearing ability, this type of vessel was better suited than the galley to wield gunpowder weapons. Because of their development for conditions in the Atlantic, these ships were more weatherly than galleys and better suited to open waters. The lack of oars meant that large crews were unnecessary, making long journeys more feasible. Their disadvantage was that they were entirely reliant on the wind for mobility. Galleys could still overwhelm great ships, especially when there was little wind and they had a numerical advantage, but as great ships increased in size, galleys became less and less useful.
