The Coast Guard rescued three boaters after their boat sank approximately 30 miles southeast of Port Royal Sound on Friday morning.
The crew of the 45-foot vessel Hangem High alerted the Coast Guard via radio they were taking on water at around 7:30 a.m., according to a news release.
A helicopter crew from Coast Guard Air Facility Charleston and a Coast Guard Station Charleston 45-foot Response Boat boat crew launched about an hour later to assist.
The helicopter crew arrived on scene at 8:34 a.m. and the vessel lost power and began to sink at 9:15 a.m., the release said.
Around that time the helicopter crew lowered a rescue swimmer to help the crew get into a life raft.
The boat crew arrived on scene at 9:35 a.m., got the three crew members and the rescue swimmer on board, and transported them all to Station Charleston.
There were no reported injuries.
