The caravel was a small manoeuvrable sailing ship developed in the 15th century by the Portuguese to explore along the West African coast and into the Atlantic Ocean. The lateen sails gave it the capacity for sailing windward. Caravels were used by the Portuguese and Castilians for the oceanic exploration voyages during the 15th and 16th centuries in the Age of Discovery, its English name derives from the Portuguese caravela, which in turn may derive from the Arabic qārib, used to refer to an ancient boat type known as carabus in Latin or καραβος in Greek indicating some continuity of its carvel build through the ages. Until the 15th century, Europeans were limited to coastal navigation, they used the barge or the balinger, which were ancient cargo vessels of the Mediterranean Sea with a capacity of around 50 to 200 tons. These boats were fragile, with only one mast with a fixed square sail that could not overcome the navigational difficulties of southward oceanic exploration, as the strong winds and strong ocean currents overwhelmed their abilities.

The caravel has origins in earlier Portuguese fishing boats built in the 13th century based on the medieval Islamic qarib, used in Islamic Spain. The caravel was developed in about 1451, based on existing fishing boats under the sponsorship of Henry the Navigator of Portugal, soon became the preferred vessel for Portuguese explorers like Diogo Cão, Bartolomeu Dias or Gaspar and Miguel Corte-Real, by Christopher Columbus, they were agile and easier to navigate than the barca and barinel, with a tonnage of 50 to 160 tons and 1 to 3 masts, with lateen triangular sails allowing beating. Being smaller and having a shallow keel, the caravel could sail upriver in shallow coastal waters. With the lateen sails attached, it was maneuverable and could sail much nearer the shore, while with the square Atlantic-type sails attached, it was fast, its economy, speed and power made it esteemed as the best sailing vessel of its time. The limited capacity for cargo and crew did not hinder its success; the exploration done with caravels made the Spanish possible.

However, for the trade itself, the caravel was replaced by the larger carrack, more profitable for trading. The caravel was one of the pinnacle ships in Iberian ship development from 1400–1600. Due to its lighter weight and thus greater speed, the caravel was a boon to sailors. Early caravels carried two or three masts with lateen sails, while types had four masts. Early caravels such as the caravela tilhada of the 15th century had an average length of between 12 and 18 m, an average capacity of 50 to 60 tons, a high length-to-beam ratio of around 3.5 to 1, narrow ellipsoidal frame, making them fast and maneuverable but with somewhat low capacity. It was in such ships that Christopher Columbus set out on his expedition in 1492. Towards the end of the 15th century, the Portuguese developed a larger version of the caravel, bearing a forecastle and sterncastle – though not as high as those carracks, which would have made it unweatherly – but most distinguishable for its square-rigged foremast, three other masts bearing lateen rig.

In this form it was referred to in Portuguese as a "round caravel" as in Iberian tradition, a bulging square sail is said to be round. It was employed in coast-guard fleets near the Strait of Gibraltar and as an armed escort for merchant ships between Portugal and Brazil and in the Cape Route; some remained in use until the 17th century.

Below is a list of the names of the rides on opening day, what they are named. Great Sea Wave, now known as The Wave Pool; the Twister and The Sidewinder, now known collectively as Swashbuckler Flumes.
