Eleven miles off the coast of the San Francisco Bay, a vital and highly dangerous operation unfolds daily as the world's largest vessels, including cargo ships up to 1200 feet long and weighing over 45,000 tons, engage with the San Francisco bar pilots. Sam Eckholm, who documented this "thrilling world" of seafaring, highlights that the "everyday commute" for these pilots involves a perilous ascent onto massive ships, often without safety nets or harnesses. Eckholm's experience climbing aboard one such vessel demonstrated the high stakes, admitting he was "stressed out the whole time," even as the pilots remained "cool, calm, collected". This elite group of expert mariners maintains a centuries-old tradition, where their specialized skill and experience are essential because even the smallest mistake could mean disaster. Ship captains lack the local knowledge—regarding the wind, current, hazards to navigation, and shallow areas—that a pilot possesses to safely dock the vessel in San Francisco.
The term "bar pilot" is derived from the massive horseshoe-shaped sandbar stretching nearly five miles offshore from the Golden Gate, through which the main shipping channel cuts a narrow, critical path. The service originated in 1850 during the California gold rush, when a surge in unfamiliar ship traffic led to an estimated 300 shipwrecks just outside the Golden Gate. The California legislature responded by creating a dedicated group of expert mariners to guide incoming ships safely, officially forming the bar pilots. Today, they are responsible for piloting any vessel over 750 tons, handling 8,000 ships annually, and contributing to about $40 billion in economic revenue across nine total ports, including Oakland, Richmond, Stockton, and Sacramento.

The pilot sector is the "pinnacle of the seafaring career". Eckholm emphasized how selective these positions are, noting that he was "blown away" when he learned the prerequisites. To become a pilot, one must be a tugboat or ship captain, a process that can take a decade or more to achieve an unlimited master’s license. For example, one test 14 years ago started with 75 people taking the written exam, only 15 made it to the simulator, and just 12 ultimately made it through.
The operation begins at the pilot station boat, a 105-foot steel hull vessel positioned 11 miles outside the Golden Gate, where pilots rest, eat, and await assignment for their demanding week-on, week-off schedule. They are transported by a runner boat like The Golden Gate, a state-of-the-art, all-aluminum monohull commissioned in 2023. This vessel, which Eckholm described as having "business class seating" and spacious living quarters, is lauded as the most EPA advanced pilot boat in the United States. Powered by two 1200-horsepower engines, it can reach speeds of about 35 knots (roughly 38 miles per hour).
The most dangerous step is the pilot-to-ship transfer. Pilots must step out onto a platform and perfectly time the move onto a ladder while the pilot boat climbs up and down the side of the massive ship, often contending with 50 knots of wind and 20-foot seas. This hazardous transfer, which lacks safety nets or harnesses, results in severe injury or death to a pilot somewhere in the world every year. Once aboard, the pilot conducts a Master Pilot Exchange, takes navigational control, and must account for the immense momentum of ships that can displace 150,000 tons, requiring turns to start a half mile before reaching the Golden Gate Bridge. Inside the bay, speeds are restricted to 15 knots, dropping below 10 knots near the Bay Bridge. Pilots constantly battle fog, which necessitates a half mile of visibility at certain points, as well as shallow water, cross currents, wind, and recreational boaters. The high stakes were tragically underscored by the 2024 container ship crash in Baltimore, confirming that bar pilots serve as the "first and last line of defense against disaster". Sam Eckholm's footage captured the satisfaction that comes with successfully docking a "massive piece of steel," a feeling described by a pilot as "a very pure sense of satisfaction".
