The Newport Beach-based Coast Guard cutter Narwhal was patrolling international waters about 100 miles off San Diego when it picked up a speedboat on radar late on Sunday afternoon 16 November 2008.[1] The boat was heading north toward the United States and sped up at sundown; when the Narwhal ordered it to stop around 7.30pm, it fled toward Mexico with its crew throwing bales overboard.[1][2] The marijuana came in 137 steamer-trunk-sized bales weighing nearly 10,000 pounds, with an estimated street value of $32 million, in what was called one of the largest marijuana seizures in Coast Guard history.[1][3]

The Narwhal handed the chase to the Mexican Navy and spent the night and Monday morning hauling the bales from the water, then turned the drugs over to a federal narcotics task force in San Diego on Monday afternoon.[1] The smugglers got away, and the haul dwarfed another marijuana recovery the same crew had made in the area in September.[1][3]
