Changing foliage and shorter days aren’t the only things Washington State Ferries’ customers can count on every fall. Seasonal service adjustments start Sunday, Sept. 21, and off-peak fares go into effectWednesday, Oct. 1. Riders on the Fauntleroy/Vashon/Southworth run will also soon make the crossing aboard a larger vessel.

As summer turns into autumn, fewer tourists and weekend passengers ride the ferry. Accordingly, WSF routinely adjusts the sailing schedule and removes the peak-season surcharge to accommodate expected ridership.

This year, WSF also adjusted the three-vessel Fauntleroy/Vashon/Southworth schedule to improve on-time performance and allow more loading and unloading time for a larger, 124-car Issaquah Class vessel. The larger ferry will replace one of the Evergreen State Class vessels on the route in mid-November.

Highlights of the 2014 fall sailing schedule:

•  Anacortes/San Juan Islands: four vessels in service, similar to spring, with an additional 11:40 a.m. stop in Shaw.

•  Anacortes/Sidney, British Columbia: one daily roundtrip sailing via Friday Harbor, down from two.

•  Fauntleroy/Vashon Island/Southworth: fewer sailings on weekends and minor sailing-time adjustments.

•  Mukilteo/Clinton: fewer late-night and early-morning sailings Thursday through Sunday.

•  Port Townsend/Coupeville: two-boat service continues until Monday, Oct. 13; one-boat service resumesTuesday, Oct. 14.

•  Seattle/Bremerton: the 144-car Kaleetan adds more capacity by replacing the 90-car Sealth.
