A husband and wife were rescued from a boat about a mile off Point Judith on Sunday by Good Samaritans who saw an explosion and came over to help, the Coast Guard said.

The explosion occurred shortly after noon in the boat’s console area, injuring Richard and Alicia Derise, of Narragansett, said Chief Wendy MacLean, of the Coast Guard station in Woods Hole, Mass. The couple were transported to shore with a Coast Guard escort and were taken to South County Hospital, MacLean said.

Richard Derise, 59 was not admitted. But Alicia Derise, 61, was transferred to Rhode Island Hospital, Providence, where she was reported in fair condition yesterday afternoon.

The state Department of Environmental Management towed the damaged boat to a warehouse at Quonset Point, in North Kingstown, andwas investigating the cause of the explosion, said Gail Mastrati, a DEM spokeswoman.
