I am doing this project on pirates and can not find any helpful resource...and l would hate to guess.

The smaller Caravel was a favorite ship of early explorers. But these ships were hard to handle with their huge sail spars and the open decks offered little protection for the crew or the stores. The only cabin space was in the stern as the forward decks had to be kept clear to allow the heel of the huge spar to swing freely. Obviously, this kind of arrangement, while it suited short coastal trips, was intolerable for long ocean voyages
It could accommodate about 20 sailors
