SEATTLE — The Wenatchee, the state's first hybrid-electric ferry, was
taken out of service on Sunday for the third time since the vessel made
its debut in July.

A Washington State Ferries (WSF) spokesperson said one of the main
engines shut down twice due to a fault in the "overspeed protection
circuit." Engineers were able to resolve the issue that same evening,
and the boat returned to service for the first sailing to Bainbridge
Island at 4:45 a.m. on Monday.

The Wenatchee is a nearly 30-year-old ship that underwent a
two-year-long retrofitting process to replace two of its diesel engines
with batteries. It's one of the biggest vessels in WSF's fleet.

Just weeks after hitting the water, the vessel was taken out of service
for the first time in mid-August for a "drive motor issue" that was not resolved until about a month later.

A WSF spokesperson said this is not unexpected for new or recently
upgraded vessels. The final stage of introducing a new ship into the
fleet is called "commissioning," which involves addressing issues that
don't arise until the ship enters service.

After that initial repair, the vessel was reintroduced, but taken out of service again in late October. That was due to a problem with one of the
ship's electrical subsystems.

The boat was returned to service on Nov. 7, before being taken out again
just two days later.

WSF's sister vessels, the Tacoma and the Puyallup, were supposed to
undergo their own hybrid-electric conversions shortly after the
Wenatchee returned to service, but that plan was postponed by Washington
Gov. Bob Ferguson to return the ferry service to its full capacity in
time for the 2026 FIFA World Cup, which will hold several games in
Seattle.
