BREMERTON — Beginning Nov. 1, Kitsap Transit’s fast ferry will switch to its winter weather schedule for its Bremerton-downtown Seattle run.

The most impactful change: Saturday sailings will not operate until the winter schedule ends in April.

However, there is an increase in fast ferry sailings during weekdays.

Starting Monday, Nov. 13, two weekday round trips will be added to the schedule.

The fast ferry will depart Bremerton Monday through Friday at 11:50 a.m. and 1:25 p.m. It then will depart from Seattle at 12:30 p.m. and 2:05 p.m.

Kitsap Transit spokesman Sanjay Bhatt said reservations will not be taken for the two new midday sailings. He said those trips will be filled on a walk-up basis.

Bhatt said in a news release that Kitsap Transit will begin opening the reservation window on the first business day (Monday through Friday) of the month, not the first calendar day of the month.

The change is being made to provide more consistency in operations and to observe official holidays, he added.

Seat reservations are taken on weekday sailings other than for the two added midday trips.
