European sea exploration began in earnest in the 15th century. In 1602 history records the travels of three ships which sailed along the California coast past Point Reyes, Drake’s Bay, Monterey Bay and Morro Bay. The trade from California to the Eastern seaboard, as well as to Europe began at the Monterey Bay Customs House. The early explorers with improved ship design and instruments utilized natural seaports in California to inaugurate major trade routes and expand the commerce of the state. The rich maritime history provides a link to the enormous role that California plays in world commerce today.
