tanja sails on tripod masts (c. 8th century AD) The fore-and-aft rig is believed to have been developed independently by the
Austronesian peoples some time after 1500 BC with the invention of the
crab claw sail. It is suggested that it evolved from a more primitive V-shaped "square" sail with two spars that come together at the hull. Crab claw sails spread from
Maritime Southeast Asia to
Micronesia,
Island Melanesia,
Polynesia, and
Madagascar via the Austronesian migrations. Their use later spread into the
Indian Ocean since the first millennium, among vessels from the
Middle East,
South Asia, and
China.
Europe The lateen was developed in the Mediterranean as early as the 2nd century AD, during Roman times. It became common by the 5th century. The square rig had predominated in Europe since the dawn of sea travel, but in the generally gentle climate of southern Europe and the
Mediterranean Sea during the last few centuries before the
Renaissance the fore-and-aft began to replace it. By 1475, its use increased, and within a hundred years the fore-and-aft rig was in common use on rivers and in estuaries in Britain, northern France, and the Low Countries, though the square rig remained standard for the harsher conditions of the open
North Sea as well as for trans-Atlantic sailing. == See also ==
