The Silvergate and the Cabrillo, two of San Diego Bay’s working vessels, have earned national recognition and were officially listed on the National Register of Historic Places by the U.S. Department of the Interior. Both vessels are owned and operated by Flagship Cruises & Events, San Diego’s oldest family-owned maritime fleet.
This designation acknowledges the cultural, architectural, and maritime significance of the vessels, which are among the city’s last remaining historic ferries still operating on the water. Both ferries have played a role in shaping the region’s identity—from serving local transportation needs to becoming beloved icons of the waterfront experience.
The Silvergate, built in 1940, served the historic commute between San Diego and Coronado, mainly to accommodate the increased passenger load to Naval Station North Island during war times. The completion of the San Diego-Coronado Bay Bridge in 1969, ended the era of the ferry as the primary mode of transportation between the two locations. Silvergate then expanded into harbor excursions and educational programming while ferry service was banned within a 10-mile radius of a toll crossing.
The vessel resumed ferry service in 1987 after construction bonds for the bridge construction were paid off and is being recognized by the National Register of Historic Places under Criterion A as a significant historical resource for its association with maritime transportation during World War II and in the post-war years as part of San Diego’s maritime recreation sector. Known for its distinctive silhouette and warm wood detailing, the ferry remains a cherished presence on the bay.
The Cabrillo, designed and constructed in 1964, is a testament to the craftsmanship and maritime tradition of the Star & Crescent Boat Company. Designed by renowned naval architect Oakley J. Hall, the vessel was built specifically for passenger service on San Diego Bay and continues to operate today with much of its original charm preserved. The ferry operated historically as an excursion vessel during the post-war maritime recreation boom in San Diego and is historically recognized under National Register Criterion A, with a period of significance of 1964-1968. Cabrillo is also recognized under National Register Criterion B, for associated significance with the life of its designer and builder, Oakley J. Hall, established by the San Diego Historical Resources Board as a locally significant individual.
The National Register of Historic Places is the federal government’s official list of historic buildings, districts, objects, and sites deemed worthy of preservation. This designation supports continued preservation efforts and ensures these vessels remain active and accessible for future generations.
Flagship Cruises & Events encourages residents and visitors to experience these historic vessels firsthand by riding during their regular public ferry service schedule.
