The Coast Guard Cutter Mackinaw (WLBB 30) directly assists the 650-foot motor vessel Algoma Intrepid near Beaver Island on Lake Michigan, Jan. 25, 2026. The Mackinaw made high-speed passes by the vessel, breaking up ice and opening navigable channels for the Algoma Intrepid to continue its transit. (U.S. Coast Guard video by Lt. j.g. William Erekson)
