The Coast Guard is establishing a temporary safety zone for navigable waters within a 250-yard radius of the MARMAC 306 cable laying barge, and a J.F. Brennan construction barge #4132. The safety zone is needed to protect personnel, vessels, and the marine environment from potential hazards created by cable laying operations being conducted in the vicinity of the West Passage Narragansett Bay, Jamestown, RI, between the Jamestown Verrazzano Bridge and south to Dutch Island. When enforced, entry of vessels or persons into this zone is prohibited unless specifically authorized by the Captain of the Port, Sector Southeastern New England.
