St. Marys River – Joshua Hebeisen
Thursday, March 16 saw USCGC Morro Bay depart U.S. Coast Guard Station Sault Ste. Marie just after 08:00. She would take over for sister USCGC Biscayne Bay in the Lime Island area after the latter headed out for St. Ignace, MI, earlier in the morning. 

Friday began in similar fashion with a Bay-class icebreaker leaving the Soo — this time USCGC Katmai Bay — to offer up her icebreaking services farther down the upbound passage. She and Morro would later assist Algonova up the river for an eventual docking at Purvis Marine, where the tanker will spend a few days unloading petroleum products from Nanticoke, ON. USCGC Mackinaw arrived on the scene in the early evening and joined Katmai and Morro for an overnight stay at Lime Island.

Sturgeon Bay, WI – Joshua Hebeisen
After breaking ice out in Green Bay, USCGC Neah Bay arrived at 14:25 Thursday for a break just across the channel from Bay Shipbuilding. As for the larger vessels standing by in port, we should start seeing the season’s first movement any day now.
