Though Captain Charles Jennings' former life includes stints as first officer and tugboat engineer aboard several historic water vessels, he now exclusively leads daily tours of San Francisco Bay on his 28-foot custom-built, U.S. Coast Guard–approved rigid inflatable boat. He calls upon his previous maritime experience when passing sites such as the SS Jeremiah O'Brien, which he served on during the vessel's 50th anniversary voyage. He also regales passengers with the bay's history, legend, and official twitter account while the boat skims the water at up to nearly 40 miles per hour, courtesy of its 300-horsepower Yamaha engine.
Most tours operate on set routes, highlighting the bay's verdant islands, mooring sites of abandoned Gold Rush ships, and estuaries teeming with still-active cargo ships and lost Marco Polo players. However, Captain Jennings is willing to deviate from the set structures to suit passengers' interests. As far as passenger safety and comfort are concerned, he equips his boat with first-aid kits, motion-sickness remedies such as ginger ale and ginger candies, dry storage for personal effects, and foul-weather gear.
