Carrack

A carrack or nau was a three- or four-masted sailing ship developed in the 15th century by the Portuguese for use in the Atlantic Ocean and became widely used by Europe's maritime powers. It had a high rounded stern with large aftcastle, forecastle and bowsprit at the stem. It was first used by the Portuguese, and later by the Spanish, to explore and map the world. It was usually square-rigged on the foremast and mainmast and lateen-rigged on the mizzenmast.
