BRISTOL (AP) – A Massachusetts man died after a recreational boat capsized Monday in waters off South Bristol, officials said.

The 21-foot Parker operated by William Merrill of Windham, N.H., and carrying three passengers was leaving Christmas Cove at 3 to 4 knots when a swell hit the boat in a way that caused it to roll over, said Sgt. Paul Joyce of Maine Marine Patrol.

Merrill and a man from Wilmington, Mass., were trapped under the boat, and the Massachusetts man was not breathing when Merrill pulled him from under the boat, Joyce said.

Merrill and a lobsterman who plucked the four out of the water after the 11:45 a.m. incident began CPR and continued the CPR while the lobster boat was escorted by a Maine Marine Patrol boat to the mainland, where it was met by an ambulance.

The victim was later pronounced dead at 1:25 p.m. at St. Andrews Hospital in Boothbay Harbor, the Coast Guard said.

The parties on the boat were related, but the Maine Marine Patrol declined to release the name of the victim Monday night.
