The US Coastguard said on Saturday that the rescue operation remains ongoing, involving multiple aircraft and boats from the Coastguard and US Navy, with assistance from the Mexican Navy. An additional helicopter is expected to be deployed later in the day.
A mayday call was received at approximately 1am on Friday from someone on the vessel, which was located about 225 kilometres (140 miles) west of Ensenada, Mexico. A rescue helicopter arrived about two hours later and took 90 minutes to pull the 16 people from the water. Survivors told officials there were 27 people on board.
"Several of the individuals rescued were suffering from severe injuries consistent with shark bites, and the Coast Guard provided life-saving first aid while en route [to] San Diego," the coastguard said in a statement.
Although the incident occurred outside US waters, Coastguard official Charlie Valor said on Saturday they "were able to help, and that's why we launched our assets".
The area is popular with fishing and leisure boats but is also used by smugglers. Fatal incidents involving migrants attempting to reach the US by sea have occurred previously. In May 2025, at least three people died when a boat capsized about 56 kilometres (35 miles) north of the US-Mexico border. In 2023, eight people died in one of the deadliest maritime smuggling accidents off the US coast when a boat capsized near a San Diego beach.
