Large marina with extensive floating docks and multiple piers accommodating numerous boats, but no visible parking lot or landside facilities in the image.
Basin 4 is a marina located in Sausalito, California, nestled along the northern shores of the San Francisco Bay, which connects to the broader Pacific Ocean via the Golden Gate Strait, offering a scenic and sheltered setting in Marin County. It primarily serves recreational sailing and boating enthusiasts navigating the calm, protected waters of the bay. This area provides access to the diverse marine environment of the northern California coast, including opportunities for day trips toward the open Pacific.
Marinas typically need to separate slip holder parking from day-visitor parking, trailer areas, launch ramps, and secure dock access points. Modern facilities use barrier gate systems to enforce these zones automatically — allowing permitted vehicles through via transponder or keycard while logging all access events.
