`
Commissioned June 10, 2006, the 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. Propulsion 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. See photos of
the pods from before the Mackinaw's launch.
