The steamboat Dauntless operated in the early 1900s as part of the Puget Sound Mosquito Fleet.

Dauntless was built in 1899 by Matthew McDowell at Tacoma to replace the Defiance (I) on the Seattle-Tacoma-East Pass run.

In 1900, Captain McDowell built a newer and larger Defiance (II) at Tacoma, and sold Dauntless to the Moe Brothers, who put the vessel in the Bainbridge Island service.

A steel mill at Irondale caused that town to boom, and Dauntless, still capable of 11-knot speed, made quick trips on this route.

[1] On December 30, 1923, a storm caused Dauntless to break loose from her moorings at Appletree Cove.
