What are some nautical considerations of Columbus?
Columbus was wrong about the number of degrees of longitude that separated Europe from the Far East.
What was he right about in terms of nautical considerations?
he did possess valuable knowledge about the trade winds, which would prove to be the key to his successful navigation of the Atlantic Ocean.
How did some of his real life voyages go?
During his first voyage in 1492, the brisk trade winds from the east, commonly called "easterlies", propelled Columbus's fleet for five weeks.
Did anything else happen during that voyage?
The precise first land sighting and landing point was San Salvador Island.
Was San Salvador Island known for anything historically important?
CANNOTANSWER.
Did anything else happen in the first voyage in 1492?
Columbus returned home by following the curving trade winds northeastward to the middle latitudes of the North Atlantic.
Was his voyage successful then using his nautical knowledge?
It is unclear whether Columbus learned about the winds from his own sailing experience or if he had heard about them from others.

Question: What sailing techniques did he use to utilize the winds?
