The Coast Guard is establishing a temporary safety zone for navigable waters within a 500-yard radius of Tug Nancy Anne, Tug Champion, Tug General, Tug WM Boyd, Tug Shirley Ann and crew boat Timmy V. The safety zone is needed to protect the remotely operated vehicle survey operations from other vessels. Entry of vessels into this zone is prohibited unless specifically authorized by the Captain of the Port Northern Great Lakes.
