The 140-foot Morro Bay is leaving its New London homeport on Monday and heading to the Great Lakes, a trip that's expected to take a few weeks.
It'll join other icebreakers and Canadian vessels to keep shipping lanes open, help mitigate flooding and make sure rescue boats and other emergency vessels can get through.
The New Jersey-based cutter Penobscot Bay spent last winter in the Great Lakes, and the Thunder Bay cutter from Maine was there in the winter of 2008 to 2009.
