The tug Henry Brusco with the 322 foot long barge St. Elias went aground between Center Island and Anacortes in the San Juan Islands, Washington.  The St. Elias was carrying cargo including 9,000 pounds of Navy munitions.  The Henry Brusco was refloated later the same day while the St. Elias was pulled free and taken to a nearby cove.   An inspection showed the barge suffered a 10 foot by 10 foot gash in the starboard hull, but the barge had no water ingress.  The Coast Guard approved the St. Elias to continue its voyage to Indian Island.   The St. Elias was escorted by three tugs and the Coast Guard Cutter Swordfish.   No reports of injuries or pollution being released.
