TRENTON, Maine — The Coast Guard credited the crew of a fishing boat with making sure safety supplies were in good, working condition, ensuring a smooth rescue after the boat began taking on water around midnight Tuesday.

According to a press release from the Coast Guard, the Coast Guard Sector Northern New England received a broken transmission around midnight from the crew of the Boston-based fishing vessel Lydia & Maya, saying they were taking on water. Shortly after, Coast Guard watchstanders received an alert notifying them the crew was in the water.

The Coast Guard deployed a 47-foot boat crew from Southwest Harbor and a MH-60 Jayhawk helicopter crew from Cape Cod.

Around 2 a.m., the helicopter reached the location broadcast by the distress signal, about 40 miles south of Southwest Harbor, and found the four crew members in a life raft, shooting flares and using a signal light.

A rescue swimmer helped get the four fishermen into the helicopter. They were flown to Hancock County Bar Harbor Airport in Trenton to be checked out by emergency medical personnel. The fishermen showed mild hypothermic conditions, according to the press release.

Chief Petty Officer Aaron Clendaniel credited the crew with helping rescuers find them quickly.

“The Lydia & Maya crew did a great job making sure their safety supplies were in good working condition, and that is what allowed us to find them so quickly,” he said.

Additional information about the crew, such as names or medical conditions, was unavailable late Wednesday afternoon, according to the Coast Guard.

This incident is not the first time the 71-foot fishing boat has made headlines. In December 2013, crew member Martin Gorham, 47, of Westbrook fell off the boat and presumably drowned in heavy seas off Cape Ann, Massachusetts.
