A Coast Guard aircrew scooped four people from a sinking fishing boat about 18 miles south of Martha’s Vineyard on Wednesday night, according to the Coast Guard.

The captain of the vessel Sea Star radioed the Coast Guard at around 6:20 p.m., saying the boat was taking on water and listing heavily and crew members were putting on their immersion suits, according to a statement from the federal agency.

Coast Guard aircrews that were on a training flight were diverted to the area, and once it was determined that the vessel could not be saved, the fishermen were ordered into the water and were pulled up into a helicopter, the statement says.

The crew members were taken back to Air Station Cape Cod and were deemed in good health.

"The most important things the crew did was activate their EPIRB (Emergency Position Indicating Radio Beacon) and don their immersion suits," Scott Backholm, a command duty officer at Sector Southeastern New England, said in the statement.

The water temperature was 37 degrees, seas were at 5 feet and the wind was up to 25 knots, according to the Coast Guard statement.

The Sea Star sank, and a marine bulletin is being issued so mariners will know of the potential hazard.
