The Coast Guard has suspended a search for a missing boater last seen fishing on the St. Helena Sound in Beaufort County on Thursday.

Missing is Gregory Moss, 53, of North Myrtle Beach.

Search and rescue controllers at Coast Guard Sector Charleston were notified by the South Carolina Department of Natural Resources at 9:17 p.m., Thursday, of Moss' disappearance. It was reported that Moss was aboard a 14-foot fishing boat with one other person when it reportedly capsized. The second person successfully swam to Ashe Island and was later picked up by another boater. 

Moss was last seen attempting to swim ashore — he was not wearing a lifejacket. 

Two Coast Guard HH-65 Dolphin rescue helicopter crews from Air Station Savannah, Ga., a 25-foot rescue boat crew from Coast Guard Station Tybee Island, three South Carolina Department of Natural Resources boat crews and one fixed wing aircraft conducted an exhaustive search throughout Friday.

The Coast Guard reminds all boaters of the importance of wearing a life jacket when navigating aboard recreational vessels and personal watercraft. In addition, VHF-FM marine band radios are encouraged for all marine activities in isolated areas where cell phone coverage can be poor.
