NAO or NAU

Post by aukepalmhof » Wed Feb 17, 2010 8:28 pm

NAO or NAU is a generic term for a 14th- to 16th century ship, and it was a three or four masted sailing vessel for use in the Atlantic.
The NAO was developed by the Portuguese, and used by them as expedition ship, warship and as escort by convoys. She was also used later by Spain, Italy and France.
Carvel built with a square stern. In general high-sided with castles forward and aft.
Midline rudder, 2 -3 decks, beamy, short keel, deep hull.
Square rigged on foremast and mainmast and lateen rigged on the mizzenmast.
Tonnage between 120 to 500 ton.

The Tanzania stamp gives that she is a caravel, but she is a nao.

THE PORTUGUESE NAU
The age of the Caravels came to an end when Cap Bojador was rounded in 1487. The prevailing Atlantic winds and currents that enabled this feat, rendered far-away voyages feasible and justified the choice of the Nau as a more suitable vessel for the Cape route. The reason was that it had much greater DW tonnage, it could carry more cargo thus enabling larger profits and also more provisions, a larger crew, passengers, as well as cannons for protection against the corsairs. Generally, the Nau had 3 decks, 3 masts (2 fitted with square sails and one with a Latin sail), a forecastle and an aftercastle, and a carrying capacity varying between 120 and 1200 tuns.
Naus that sailed on the so-called “Carreira da Índia” (India route) played a leading role on the annual trade route between Lisbon and Goa, initiated with the discovery of the maritime route to India, a voyage that Valignano in 1574 described as being “the longest and most trying voyage there is”. A true odyssey, which documents, in a dramatic way, our “história trágico-marítima” (“tragic history of the sea”), a narrative of dramatic shipwrecks that occurred in those times.
