JUNEAU, Alaska (KTOO-FM) — The state plans to use one of its ferries to provide service between two southeast Alaska communities while repairs are done on an Inter-Island Ferry Authority vessel. CoastAlaska reports the authority’s link between Ketchikan and Hollis on Prince of Wales Island was shut down last Friday. The authority says there was a propulsion system failure on one of its vessels. Repairs to a sister ship were delayed by the inability of technicians to travel from the continental U.S. The authority is separate from the state-run marine highway system, which announced plans Wednesday to provide temporary, limited service between the communities.
