My daughter and I took the boys and My love to the ship my grandfather helped build. My Papa was a ship builder back in Quincy, MA as a young man. He served in the U.S. Navy, and he worked into the ship yard.
I cannot remember if it was the front or the back of the boat, but there is a piece of metal that holds my grandfather and a co-workers name. They etched their names on the metal, and then riveted it to the ship.
