The Vessel and Her Loss

YMS-416 was built in 1944 and served as a Navy auxiliary motor minesweeper before being struck from the register in 1947 and sold as surplus. Her fate afterward went unrecorded for decades until dive researchers identified her wreck in Lake Washington near Sand Point. At some point after her Navy career, she was stripped of equipment and scuttled, and she now lies alongside two other identified YMS-class wrecks in roughly 200 feet of water.
