As autumn semi-officially arrives this Sunday with the month of October, officials at Washington State Ferries will be dialing back the frequency of some cross-Puget Sound sailings.

But the summer surcharge will end, too, which means a slight reduction in ferry fares to and from destinations on the Olympic Peninsula and into north Sound harbors.

Southworth to Vashon Island and on into west Seattle will see fewer weekend sailings after Sunday. The Port Townsend to Coupeville (Vashon Island) will also scale back to one vessel, instead of two, meaning about half as many scheduled runs.
