Dart was built in 1911 by Matthew McDowell at Tacoma for his steamboat line's Seattle-Tacoma-East Pass run.[1]Dart a small vessel even by Mosquito Fleet standards.[2]
Dart ran on the Seattle-Tacoma-East Pass route until about 1918, when Captain McDowell sold her to the Wrangell concern of W.T. Hale and P.C. McCormick, who converted Dart to a motor vessel to run mail between Wrangell and Prince of Wales Island. Later, he sold Dart to Paul S. Charles of Ketchikan interests.[2]
In 1925 the Anderson Tug Company purchased Dart and returned her to Puget Sound to operate as a tug. In 1928 Dart burned on the Sound while awaiting scrapping. Her engines were salvaged and placed in the ferry City of Mukilteo. Her hull, still good apparently, was rebuilt as a diesel freighter and sent to work routes out of Juneau.[2][3]
