SS California arrives in San Francisco Bay, opening regular transcontinental steamship service

Background. The SS California was built for the Pacific Mail Steamship Company, founded in 1848 by New York merchants. It was the first of three steamships specified in a government mail contract to provide service to Oregon and California. The vessel was built in New York in 1848, with its keel laid in January and launch in May, preparing it for the transcontinental route.

Voyage Details. The California departed New York Harbor on 6 October 1848 with a partial load of passengers. It rounded Cape Horn at the tip of South America, completing a four-month, 21-day journey. The ship arrived in San Francisco Bay on 28 February 1849, establishing the first regular steamship service from the East Coast to the West Coast of the United States.

Significance. The arrival of the SS California marked the beginning of regular scheduled steamship service linking the US coasts. This service was crucial for mail, passenger, and freight transport to the newly acquired territories of Oregon and California. The vessel's operation facilitated the movement of people and goods, contributing to the development of San Francisco as a major seaport.
