This Thursday is a Dangerous Cargo day. When the DG is coming only to Thetis, they off-load the cargo and can take on vehicles and passengers for the 9:10 sailing. But when there is DG for Penelakut as well, that DG remains on board the 9:10 sailing and nobody else can go on. That's currently the situation for this Thursday, as well as eliminating access to the 12:30 sailing out of Chemainus for Thetis customers, and of course, the 1:25 from Thetis as well. For a list of future Dangerous Cargo days, with an effort to update when there's a situation like this week's, check out the combined busy ferry schedule on thetisisland.net.
There's a link from the homepage, from the ferry webcam page, or directly from here: http://www.thetisisland.net/ferry/current-combined-busy.pdf If you know of days when there will be extra stress on ferry traffic, please let me know, so it can be included on the combined schedule.
Thanks!
