SEABROOK ISLAND — A 20-year-old kayaker was found safe, if mildly dehydrated, after a two-hour search of the Atlantic Ocean by sea and air Wednesday afternoon, the U.S. Coast Guard said.

Joe Stevenat was wearing a life vest when he paddled away from his father's sailboat near the North Edisto River around 2:30 p.m., said Petty Officer 1st Class Donnie Brzuska, a Coast Guard spokesman.

The father called 911 about two hours later when Stevenat hadn't returned from what was supposed to be a short kayaking trip.

Around 6:30 p.m., a Coast Guard helicopter spotted Stevenat about a mile from Seabrook Island, Brzuska said.

A state Department of Natural Resources rescue crew brought him to Cherry Point boat landing.

The Charleston County Sheriff's Office, Charleston County Rescue Squad and Seabrook Island public-safety officials aided in the search.

In May, two men in their late 20s disappeared after they set out in a kayak from Seabrook Island.

The Coast Guard rescued one of them 18 hours after he drifted about 20 miles away, clinging to the kayak.

The rescued man's friend could not hold on, and did not survive the ordeal.
