SEATTLE (AP) — Puget Sound ferry travelers can expect summer delays because of last month’s fire aboard the ferry Wenatchee, which has forced the state to use smaller vessels than normal on several routes.

Washington State Ferries is operating 18 vessels instead of the usual summer fleet of 19 boats. Besides a reduced number of ferries, they say crew shortages and quarantines further limit capacity, just as peak travel season begins.

Lower-capacity schedules take effect Thursday night.

The jumbo ferry Wenatchee remains docked at Eagle Harbor on Bainbridge Island following the April 22 fire.
