Multnomah (sidewheeler 1851)
The ''Multnomah'' was one of the first steamboats to operate on the Willamette and Yamhill rivers. This vessel should not be confused with the ''Multnomah'', a steamboat built in Portland, Oregon in 1885, which was larger and of a much different design.
==Design and construction==
The components of ''Multnomah'' were manufactured in the eastern United States, then shipped to Oregon City, Oregon around Cape Horn on the bark ''Success''.〔〔 At that time, there were no locks at Willamette Falls, so it was important to determine whether a boat would be built above or below the falls. In the case of ''Multnomah'', the vessel was assembled at Canemah, a settlement above the falls.〔 This allowed the vessel to run on the upper Willamette, running south from Canemah through the Willamette Valley. ''Multnomah'' 's hull was barrel-shaped, and held in shape with iron hoops which made caulking unnecessary.〔 The ''Multnomah'' was a sidewheeler, as were all the boats operating in Oregon before 1854.〔 The vessel's funnel was equipped with a spark arrester.〔〔Faber, ''Steamer's Wake'', at 38.〕
