MarineLog reports that both Senators from Michigan have requested “Robust” funding for a “Heavy Icebreaker” for the Great Lakes.
OK they called the Mackinaw a heavy icebreaker, and we know it really is not, so something less may work.
Looking at the excess Shell icebreakers we talked about earlier, it appears the already built icebreaker Aiviq, with a beam of 80 feet, is a little too large to squeeze through the St. Lawrence Seaway, but if Tups was right, and this is the icebreaking vessel Shell had under construction at Edison Chouest, its beam, 22 meters (72.2 feet) is less than the 78 foot maximum for the Seaway. Maybe something could be worked out.
This is a lot larger and more powerful than USCGC Mackinaw.

Being somewhat cynical, if this was more than a political gesture, I would have thought they would have gotten signatures from Senators from other states that border the Great Lakes.
