A faulty satellite antenna was the culprit in the loss of the ferry MV Puyallup from the Bainbridge Island-Seattle route on Sunday, according to Washington State Ferries.

The Puyallup was pulled from service at 5:30 p.m. Sunday, Feb. 22, and the loss of the vessel prompted long waits by travelers at the terminals on Bainbridge and in Seattle.

Seven sailings were cancelled on the route between 5:30 and 11:40 p.m. Sunday.

Broch Bender of the Ferries Division said Monday the Puyallup couldn’t sail due to a faulty satellite compass antenna that needed to be replaced.

The vessel relies on the satellite compass antenna for accurate GPS navigation, Bender explained, and WSF was able to replace the malfunctioning antenna with a similar antenna from another Jumbo Mark II vessel.

The Puyallup was put back into service with the first early morning sailing at 4:45 a.m. Monday out of Bainbridge Island.
