Vanderbilt's company had had an exclusive contract ferrying passengers across the isthmus through Nicaragua, but in 1856 the Nicaraguan government cancelled the agreement.
The ship was then sold to Captain John Wright, renamed Commodore and put on West Coast routes, including from its new home port of San Francisco to Vancouver, British Columbia, as gold prospectors travelled to the Fraser Canyon Gold Rush.

The ship played a small but symbolic role in the history of the state of Oregon.
After President James Buchanan signed the bill admitting Oregon to the Union on February 14, 1859, the news was wired to St. Louis, carried by stagecoach to San Francisco, and loaded on Commodore on March 10.
On March 15, the ship docked in Portland, delivering the official notification of statehood to the people of Oregon.

By 1861, the ship had fallen into disrepair and was sold again to the California Steam Navigation Company, who retrofitted it, restored the original name of Brother Jonathan, and kept it on the northward route from San Francisco to Vancouver via Portland, allowing prospectors to work the Salmon River Gold Rush.
Over the next several years, the vessel gained a reputation as being one of the finest steamers on the Pacific Coast, being the fastest ship to make the run, sixty-nine hours each way.

However, in the summer of 1865 the ship suffered a collision with a barkentine on the Columbia River, damaging the hull.
Captain Samuel DeWolf, who had just assumed command of the vessel in June, recommended that the ship be repaired in dry dock, but the company performed the repairs while still in the water, as there was so much business that a backlog of cargo began to form.
