PERILOUS VOYAGE: THE MANILA GALLEONS
The Spanish were mining silver on the Mexican Pacific coast and getting it back to Spain meant overland travel through desert and jungle till they they reached the Gulf of Mexico.
Ships tried to sail directly from Manila to the New World but were thwarted by the winds
Finally, a friar navigator (love that) reasoned that Pacific winds may blow in a circular pattern and sailed North to the latitude of Japan, where he caught the Westerly wind and was also aided by the Kuroshio Current. On the return journey, he sailed South and then turned towards home.
The ships, built of Manila teak, were huge. They carried Chinese silks and porcelain and slaves (rebellious Moros, who are still fighting to this day) and the Westward crossing took 4 or 5 months.
They would make landfall around San Francisco, sail down the coast to Acapulco, load up with silver and return via the Marianas -- which was a quicker trip.
Once in Manila, the silver was shipped to Spain in smaller vessels, occasionally running the gauntlet of Chinese and other pirates
Provisioning was vital, as a Manila Galleon could get becalmed. One ship arrived on the American coast after 6 months with 350 of the 400 aboard dead from thirst (can you imagine the struggle for water?).
The Manila Galleons sailed this route for a couple of centuries.
