A Kingston, Mass., man and his brother are being hailed as heroes after rescuing two capsized boaters from the frigid waters of Cape Cod Bay.

Richard Greenwald and his brother, Tommy Menendez, were fishing about a mile off Gurnet Point Sunday morning when through his binoculars Greenwald spotted what first looked like a dolphin cresting in the distance.

On closer inspection, Greenwald realized he was looking at the capsized bow of a boat.

“There were 4- or 5-foot swells,” one of the rescuers said. “It must have been a scary feeling. We were the only ones out there.”
