Life-Line was designed by George H. Hitchings and built at Coos Bay for Reverend G. L. Hall of the American Baptist Publication Society. The vessel was 40.0 feet (12.19 m) long, propeller-driven, with a 24 horsepower gasoline engine.
Once complete, "this little ship, under zealot Captain Lund, ran up and down the coast for the Baptist Missionary Society, saving the souls of erring seamen and longshoremen alike."
On June 5, 1923, Life-Line was being taken north from Coos Bay to Kelso, Washington, under command of Captain Lund who was operating the vessel with a deckhand. Life Line foundered off the coast, just south of Neahkahnie, and Captain Lund and the deckhand swam to shore. The vessel washed ashore and was later covered by the sand, where it was forgotten until 1949, when a bulldozer uncovered the wreck.
