Dramatic video shows a chopper rescuing a woman and two children stranded on a boat that capsized off the coast of Puerto Rico after the island was slammed by Hurricane Maria.

The people aboard the Ferrel sent out an emergency message saying they were disabled and adrift Wednesday in 20-foot seas and 155-mph winds near Vieques, according to the US Coast Guard.

The Coast Guard and the British Royal Navy coordinated the rescue mission that was captured Thursday by Petty Officer 2nd Class Ashley Johnson, Metro UK reported.

A British man died after being trapped in the vessel, but the woman and two 12-year-old boys — believed to be his family — can be seen waving at a British helicopter as it arrives to pluck them off the boat.

The family had spent a terrifying 24 hours on the 146-foot former oceanographic research vessel, which could not withstand the catastrophic power of the Category 5 hurricane.

It was only after Maria passed and weather conditions improved that the rescue mission could be launched by the Coast Guard, which deployed a plane and a cutter, and the British Navy, which sent a ship and a helicopter.

A signal from the radio beacon led the rescuers to a point just off Vieques — 50 miles from where the initial distress call was made.

“We initially got the call — a vessel in distress, a family of four — north of St. Croix, literally in the teeth of a hurricane,’” Coast Guard Rear Adm. Peter Brown said, the Daily Mail reported.

“We were obviously concerned,” he said. “We didn’t ask their names and didn’t ask why they were out there.”

After completing the rescue, the chopper flew toward a carrier, where the three were led to safety.

“There was obvious joy in the command center when the aircraft spotted them and the helicopter hoisted them to safety,” Brown said.
