The ship that truly launched the first phase of the Portuguese discoveries along the African coast was the caravel, a development based on existing fishing boats. They were agile and easier to navigate, with a tonnage of 50 to 160 tons and 1 to 3 masts, with lateen triangular sails allowing luffing. The caravel benefited from a greater capacity to tack. The limited capacity for cargo and crew were their main drawbacks, but did not hinder its success. Limited crew and cargo space was acceptable, initially, because as exploratory ships, their "cargo" was what was in the explorer's feedback of a new territory, which only took up the space of one person. Among the famous caravels are "Berrio" and "Caravela Annunciation".
