10:24 PM: Thanks for the tips on this – the 9:30 West Seattle Water Taxi run from downtown, and 10 pm run from Seacrest, have been canceled, and multiple passengers waiting on the downtown dock tell us they were told a “security breach” is to blame, but that there’ll be a sailing from downtown soon. The first tipster tells us – and the online Water Taxi Watch verifies – that the Doc Maynard was parked at the nearby maintenance barge instead of Pier 50 while this was investigated. Working to find out more.

10:39 PM: We’ve heard back from both Jeff Switzer with KC Department of Transportation and Greg Lerner from the Marine Division. Both say a trespasser was being investigated at the Water Taxi maintenance facility, that Seattle Police responded, and that passengers should be on a sailing headed this way shortly. Water Taxi Watch shows Doc Maynard has now moved over to Pier 50.

10:47 PM: One passenger tells us police are still in view, checking out the other two Water Taxi vessels (the maintenance barge is a short distance south of Pier 50 downtown). Vessel Watch shows Doc Maynard now headed this way.
