MARTHA'S VINEYARD, Mass. (WLNE) - The Coast Guard has called off the search for three missing fishermen from a New Bedford scalloping boat that capsized off the coast of Martha's Vineyard Sunday. 

"I guess a wave came over the side. They didn't have the scuffers up, so the water couldn't flow out fast enough so basically made a swimming pool out of the deck, and another wave ended up coming I guess," said Dillon Martins, the grandson of the owner of the boat.

New Bedford Mayor Jon Mitchell tweeted Monday night: "#NewBedford mourns the loss of the crew of the F/V Leonardo, and we extend our prayers and support to their families."

Meanwhile, the Coast Guard is sharing a video showing Sunday's rescue of one man from that boat, Ernie Garcia.

"He's a lucky man," said Martins. "He suffered from hypothermia and he was trying to help the other man get onto the life raft, and couldn't do it."

In the whipping winds and rain, and relentless waves, the Coast Guard was unable to rescue Mark Cormier, Capt. Gerry Bretel and his son Xavier Vega.

"A mom lost her husband and her son. It's a tragedy," said Martins.
