what nautical developments helped make christopher columbus voyage possible?

Question

& is there any website that has lots of info on this kind of stuff?

Answer 1

Carl is confused. Galileo was born 70 years after Columbus sailed, and the sextant is an EIGHTEENTH century invention.

Key advances that enabled the voyages of discovery of the 15th century involve improvements in the magnetic compass, the astrolabe and in shipbuilding. Before this time, NO ships (anywhere in the world) were able to sail for weeks on end in the open ocean.

As far as ships, there was the invention of the carrack and caravel, ocean-worthy vessels, along with the Arab lateen sail. (Columbus's flagship, the Santa Maria, was a carrack; the other two were caravels.)

Also, though it's not precisely a "nautical" development, do not forget other factors, such as the growth of nation-states and economic systems that were eager to undertake such voyages and had the means to FINANCE them. (Competition, such as that between Portugal and Spain for new trade routes, played a key role.)

Christopher Columbus
Perhaps the most famous explorer was Christopher Columbus. Born in Genoa, Italy, in 1451 to a weaver, young Columbus first went to sea at the age of fourteen. As a young man, he settled in Portugal and married a woman of noble background.


Columbus, Christopher
European discoverer of the New World, born in Genoa, Italy. He went to sea at 14, was shipwrecked off Portugal, and settled there c. 1470. His plans to reach India by sailing West were rejected by John II of Portugal, but finally supported by Ferdinand and Isabella of Spain.


Christopher Columbus
After five centuries, Columbus remains a mysterious and controversial figure who has been variously described as one of the greatest mariners in history, a visionary genius, a mystic, a national hero, a failed administrator, a naive entrepreneur, and a ruthless and greedy imperialist.


Christopher Columbus (1451-1506)
The best available evidence suggests that Christopher Columbus (Cristoforo Colombo in Italian; Cristobal Colon in Spanish) was born in Genoa in 1451. His father was a weaver; he had at least two brothers. Christopher had little education and, only as an adult, learned to read and write.

Christopher Columbus
One cannot begin to understand Christopher Columbus without understanding the world into which he was born. The 15th century was a dynamic century, a century of change. There were many historical events throughout Western Europe that impacted society profoundly. Directly affecting the future explorer much closer to home, however, were three momentous events in and around the Mediterranean:


The Voyages of Columbus


The First Voyage
Christopher Columbus departed on his first voyage from the port of Palos (near Huelva) in southern Spain, on August 2, 1492, in command of three ships: the Niña, the Pinta and the Santa Maria. His crew mostly came from surrounding towns such as Lepe and Moguer.


The First Voyage of Christopher Columbus
Columbus departed Palos, Spain, with three ships on August 3, [1492]. The Nina, a lateen-rigged caravel, was captained by Martin Alonzo Pinzon. The Pinta, a square-rigged caravel was captained by Pinzon's brother, Vicente Yanez. The Santa Maria, a nao, was Columbus' flagship.


Land is Sighted
The greatest obstacle to Columbus was the crew's beliefs and superstitions. They believed the earth was flat, that the sea was full of monsters, that there were places where the sea was at the boiling point, or there were endless whirlpools. The voyage lasted longer than Columbus expected.


The Second Voyage of Columbus
With 17 ships, 1,200 men and boys including sailors, soldiers, colonists, priests, officials, gentlemen of the court, and horses, Columbus set out on another journey to the west. He left the port of C diz, Spain, on September 25, 1493 aboard the Mariagalante, his flagship.


The Third Voyage of Columbus
The monarchs financed yet another voyage for Columbus. On May 30, 1498, Columbus set sail with six ships. After a stop at the Canary Islands, three set sail for Hispaniola and three with Columbus at the lead, took a southern route.


The Fourth Voyage of Columbus
Anxious to win back his good name and discover riches in the Far East, Columbus set sail once again for the new lands. He left Cadiz on May 9, 1502, with four ships and 150 crewmen, one being his 13-year-old son, Diego. He arrived in Hispaniola on June 29 only to be forbidden to land lest he stir up trouble in the colony.


What Did Columbus's Crew Eat on Their Voyages?

Columbus's Ships


Columbus's Ship
As everyone knows, Columbus had three ships on his first voyage, the Niña, the Pinta, and the Santa Maria. The flagship Santa Maria had the nickname La Gallega. It was a nao, which simply means "ship" in old Spanish; today, we might call such a ship a carrack. S
