Although later converted to diesel power, Concordia was the last inland commercial steamboat ever built on either Puget Sound or the Columbia river.

The volume of business on the company's major route, from Tacoma to Quartermaster Harbor, had fallen off, and would not support the larger vessel.

Four feet of hull were then omitted from the final design on the stern end, which gave the completed vessel a truncated or lopped-off appearance.

In 1942, Concordia passed into the hands of Joe Boies and Irving Frank, doing business as Harbor Island Ferries.

[4] Nowaczyk and his wife Beverly restored and maintained the Concordia and moored on Lake Union at the foot of Stone Way Ave N until 2020.
