Two people were rescued Thursday afternoon after their fishing boat caught fire off Fripp Island, according to the U.S. Coast Guard.

The two people aboard the 67-foot vessel evacuated at about 3 p.m. into a life raft, Petty Officer Anthony Soto said. As response boats launched from Coast Guard Station Tybee Island, Ga., another fishing boat retrieved the two from the raft and brought them to a Port Royal shrimp dock, Soto said.

Neither person requested medical assistance, Soto said.

It was unclear Friday how long the boat burned. Soto said the fire was smoldering by the time a Coast Guard helicopter flew overhead to assess the damage.

The Coast Guard did not observe any pollution from the boat Thursday or at about 12:30 p.m. Friday, when it sent out another helicopter

The boat remains lodged in the rocks off Fripp Island, Soto said. The fire's cause was not available Friday.
