The Nina and Pinta, two of the ships in Columbus' fleet were known as caravels. A caravel had a shallower draft than a nao (Santa Maria), so it could move around in the water more easily. A caravel was 150-300 tons. It did not have much cargo space, but it was able to sail over difficult waters easily. It was square-rigged on its foremasts and mainmasts, but used a lateen sail on the mizzen to help in tacking. It was so easy to control that sailors could easily explore shallow bays and the mouths of rivers. A caravel could hold about twenty crew members. They usually slept on the deck and would go below only if the weather was bad. Pinta was a caravel, a smaller, lighter, and faster ship than the tubby Santa Maria. Nina had three masts, and most likely carried sails like those of Santa Maria, except for the topsail, and perhaps the spritsail.
