Their fishermen gave a lot of information on the behaviors of the Atlantic, which in turn gave the Portuguese essential knowledge on how to train their sailors, how to perform their deep sea exploration, and things to document about their history.
2. Their ships. Each of the ships they sailed gave them a better understanding of the conditions required for safe travel across water.
3. Last but not least, religion. Jewish people driven out of Spain took refuge in Portugal and spread their beliefs, which received a small degree of persecution, yet still managed to root its place in Portugal, and serve as its advantage in trading with a wider range of countries.
