USCG Hollyhock / MESABI MINER, Near Straits of Mackinac, MI, USA (NTSB DCA14PM005)Report published Apr 8, 2015
The National Transportation Safety Board determines the probable cause of the collision between the United States Coast Guard cutter Hollyhock and the bulk carrier Mesabi Miner was the lack of effective communications between the two vessels’ bridge teams during icebreaking operations, which resulted in an insufficient amount of time to take action to avoid a collision.
The report names a ship "USCG Hollyhock" but prints no IMO number; the name matches this vessel only. It may be a different ship.
