Julie, Eliza and Douglas Sheehan, descendants of Coast Guard hero Signalman 1st Class Douglas Munro, hold honorary plank owner plaques and unit coins gifted to them from the captain and crew of the Coast Guard Cutter Munro in Seattle, March 31, 2017. Plank owner is a nautical term that denotes someone who was actively engaged in the construction of a ship and served in the unit once the vessel was commissioned and placed into service.
