Duluth, MN (NNCNOW.com) --- The 140–foot ice breaking tug underwent in–water repairs to her rudder over the weekend.
The Cleveland–based cutter has been moored in Duluth for a week since her rudder was damaged while breaking ice near Thunder Bay. The Morro Bay left the Duluth Superior Harbor this morning.
Upon further inspection, naval engineers determined that ice breaking exacerbated a preexisting problem with the rudder's bolts that fasten it to her post.
The cutter has undergone necessary repairs and is back to breaking ice on the Great Lakes.
