The Klahowya served nearly all of her career on the Fauntleroy-Vashon-Southworth run before being moved to the San Juans to replace her sister ship,, which was to be retired. In early 2008, and again in August 2012, she did short stints on the Inter-Island run due to a vessel shortage. She was moved to the Inter-Island route on June 30, 2014[1] and remained there until her retirement in January 2017. In August, 2024 it was announced that the vessel had been sold to a recycling company in Ecuador.
Klahowya is a greeting in Chinook Jargon.
