A light sheen of oil or fuel surrounded a shrimp boat grounded on the south jetty of the Charleston shipping channel, too light to be cleaned up, the Coast Guard reported Tuesday.

Salvage divers found the 60-plus foot Capt. Snorky breaking up underwater. Its removal is underway, but salvage operations are being handled delicately to keep the fuel tanks from rupturing, said Petty Officer 1st Class Lauren Jorgensen.

"The vessel is still out there right now," she said. The Coast Guard will conduct morning flights over the site to monitor potential pollution until the ship can be salvaged. The sheen is expected to dissipate.

Three people aboard the ship were rescued Sunday when it struck the jetty and sunk three-fourths underwater.

The Capt. Snorky operates from Fernandina Beach, Fla. It's a relatively long shrimper with large carrying capacity, one of a number of boats that tend to roam the Southeast coast looking for good catch.
