For more than 30 years, seafarers have boarded the Ranger 85 to catch sightings of aquatic life gliding around the waters of Channel Islands National Park and National Marine Sanctuary. Throughout the three-hour tours, passengers lean against the railing of the 85-foot ocean liner’s wraparound deck, scanning the currents for fauna such as whales, sea lions, sharks, and dolphins. Seabirds flutter in and out of view, and the recorded narration educates voyagers on the differences between gray, humpback, pilot, and orca whales, including which pet names they’re more likely to respond to. Excursions include a shoreline tour of one of the Channel Islands, just a few miles from the coast, with additional narration that explores the islands’ history.
