So far, this has been the season of late-running ferries. According to Washington State Ferry Public Information Officer Ian Sterling, the problems mostly stem from the Yakima's propeller problem. It can't be fully repaired until space opens up in a repair facility at the end of July.
Because it has to run slowly to avoid more damage, it obviously doesn't meet it's scheduled sailing times. The Samish gets stacked up behind it and ends up running late. WSF is planning to change the Yakima's position in the schedule towards the end of July. This would allow it to tie up midday and catch up to its schedule.
Sterling said, "Obviously, there are other variables such as heavy traffic, etc. We considered temporarily changing the schedule or removing the vessel from service, but the FAC (ferry advisory committee) and others indicated that those were not the preferred options. What I can reiterate is that the captains can indeed speed up as needed and that the delays are not due to any fuel savings operational concerns."

A strange declaration indeed,Report
"What I can reiterate is that the captains can indeed speed up as needed and that the delays are not due to any fuel savings operational concerns."
I have on numerous occasions personally observed ferries here (other than the Yakima) on direct routes with no intervening stops lose time compared to the stated schedule. And since the schedule has fairly tight terminal sharing, even small delays have a cascading effect on other ferries being delayed.
