Technological innovations like improved navigational tools (such as the compass and astrolabe) allowed explorers to more accurately navigate across oceans. Additionally, advancements in shipbuilding, like the development of the caravel and improvements in sail design, enabled ships to sail longer distances and withstand harsher conditions, making long-distance exploration more feasible.
