Happy Birthday to you, U.S. Coast Guard Icebreaker Mackinaw!
June 9, 2012
The United States Coast Guard Cutter Mackinaw (WLBB 30) has its 6th birthday tomorrow. MightyMac.org has this to say about the United States Coast Guard Cutter Mackinaw:
Commissioned June 10, 2006 Mackinaw (WLBB 30) assumed the “Mackinaw” name and heritage and now stands as the largest United States Coast Guard Cutter on the Great Lakes. WLBB 30 is configured to better handle a variety of roles including buoy maintenance, and handling of environmental spills.
The Mackinaw is powered by 3 Caterpillar 3612 Turbocharged V-12 engines – 3360 KW each. Prolusion comes from 2 ABB azimuthing electric propulsion drives where the propulsion motor is installed inside a submerged azimuthing (unlimited 360 degrees) pod and coupled directly to an extremely short propeller shaft.

You can see the Mackinaw every year at the Grand Haven Coast Guard Festival (July 27 – August 5, 2012). Her predecessor is now the Icebreaker Mackinaw Maritime Museum in Mackinaw City.
