A regular reader wanted to share this video. This was his comment.
I did not know where to put this, so I found one of the stories about the 140′ Ice Breaking Tugs in the Great Lakes
Below is a YouTube link of the USCGC Katmai Bay breaking ice up in Sault Ste. Marie as it was escorting a tanker.
Beautiful close up shots of her after the 20min mark, and you can clearly see her bubbler system working as she slices through the ice.
Just wanted to share this, as these 140’s are a unique asset in the Great Lakes – Very well made ships that still look strong (where’s the 140′ Replacement Program Congress!!).
Are we not allowed to post YouTube Links?? In not, please go search on YouTube for: “USCGC Katmai Bay making a path through the ice for Algonova going to the Soo on Jan 31st, 2025”
So I am passing it along.

Cutters at work!
More 140′ Cutter Icebreaking video!
This time, the USCGC Morro Bay was passing through Marine City and Algonac. The video ends with Morro Bay mooring up for the night in Algonac.
Again, more great video (and up-close) of the bubbler system on these 140’s that is used to help break up ice.
I won’t comment on the procedure involved with tying up although, I wish that the police officer line handling and all others involved on the pier would have had on some sort of life jacket. Oh, and the residents just casually walking around mooring lines with a cutter trying to moor (anyone remember that video “Line Snap” that we saw in Boot camp)!
Enjoy!
