The Katmai Bay was built in Tacoma, Washington in 1978 and is stationed at Sault Sainte Marie, Michigan. She is a 140 foot Icebreaking Tug, using a low-pressure-air hull lubrication or bubbler system that forces air and water between the hull and ice. This system improves icebreaking capabilities by reducing resistance against the hull, thereby also reducing horsepower requirements.
The US Coast Guard cutter Morro Bay left Duluth a week ago and on March 28, 2014, she was towed back to port by the Alder after sustaining damage to her rudder while breaking ice. Outside the Duluth piers, they lashed the Morro Bay to the side of the Alder for the trip through the ship canal. The Katmai Bay, also here a week ago, led them in to port.

Above, the Katmai Bay docked at the DECC on December 10, 2013. She arrived the day before to assist in ice breaking duties. Below, with most of the ice she brought in gone, she was out in the harbor breaking ice on the 16th.

  1. Saw the Katmai Bay (I think it was her hull) departing Duluth blowing one long all the way through the canal and out into the Lake at 9:11. It was very difficult to see because of the soupy conditions in Duluth until she was right next to the camera and then I could barely see the outline of Coast Guard 101. Duluth weather — never a surprise!

  2. What is the Katmai Bay doing at the DECC? Is there that much ice in the area for her to break up or is there something else going on? She is a much older and smaller ship than the Alder — different class?

    • donna, she arrived on the 9th. i think she’s been tied up at the DECC the whole time. not sure why. don’t think ice is an issue with daytime temps near forty the last couple of days. above freezing at night.

    Is she still run by coast guard
