What new technology allowed the spanish and other europeans to venture across the atlantic ocean?

I believe The new technology they used to allow them to a venture across the Atlantic ocean were compasses, cartography ( to improved map making), carabells (to help improved ship designs), and lateen sail (triangular)

Hope this helped :)
