A crew member who was under the weather prompted several cancelled sailings over the weekend of the Port Townsend to Coupeville ferry route.

Marta Coursey, spokeswoman for Washington State Ferries, said in an email that a crewman called in sick Saturday morning, leaving the Salish without a large enough crew to make its sailings. That prompted the 8:45 a.m. and 10:15 a.m. sailings from Port Townsend and the 9:30 a.m. and 11 a.m. sailings from Coupeville to be canceled.

Another crew member called in sick Sunday, which prompted the cancellation of the 10:15 a.m. sailing from Port Townsend and the 11 a.m. sailing from Coupeville.

Coursey said the operations center works diligently to find replacement personnel when someone calls in sick, but delays occur if staff can’t find replacements in time for a scheduled sailing.

Earlier on both Saturday and Sunday, low tide conditions forced officials to cancel several other scheduled sailings.
