A caravel is a type of ship made from a single stern caste. These types of ships were used by the Europeans for their explorations of different lands unknown to them during the early days. Up to this day, the way a caravel looks is still debatable and historians are yet to find their answers. Through time these caravels were reliable because they can be easily maneuvered, their speed was incredible and yet they perform safe in the waters. The caravels gained their fame through the Spanish and Portuguese voyages that discovered lands far from their imaginations.
