The Coast Guard was searching late Tuesday for a Mount Pleasant man missing after his boat overturned about 16 miles offshore.

Ronald Fowler, 36, was last seen at noon Monday, the Coast Guard said. Another boater about 1:30 p.m. Tuesday spotted Fowler’s 17-foot skiff overturned off Charleston.

Coast Guard Sector Charleston launched a search-and- rescue effort, and about 2 p.m., a helicopter crew from the Coast Guard Air Facility in Charleston arrived. The overturned boat was identified as Fowler’s. Anyone with information is asked to call Coast Guard Sector Charleston Command Center at 740-7050.
