I would assume they're going to eventually berth fit a Salish class (if not the Orca then one of the other two) at every dock that's ever been visited by everything from the Capilano/Cumberland thru the Burnaby/Nanaimo.
Quinitsa disappearing from Saltery Bay in the next few days will be a good indicator of the Orca overnighting there. I'm guessing they'll park the Orca at Buckley Bay if they're feeling good about letting her be 'far' away from Deas.
How much taller does anyone figure the Salish Orca is than the Island Sky. I went to tsawwassen yesterday and she looks quite tall, the reason I'm asking is on family day I was on the island sky and it was high tide and the clearance above the island sky from the transmission lines in jervis inlet didn't look like it was very much.
They always look close, I remember thinking that the Powell River Queen barely missed them. I have a marine chart that shows the minimum cable clearance as 160ft/48m, but I don't have the air draft of the vessels...

Over the next month, Salish Orca will conduct dock trials at ports in the Southern Gulf Islands, Sunshine Coast, Departure Bay, Duke Point, Horseshoe Bay and Swartz Bay. As part of BC Ferries’ commissioning process for any new class of vessel, ships conduct dock trials at a variety of locations for potential future deployment purposes, corporate planning and contingency scenarios.
I'm just so confused regarding the purpose of the dock trials.
Note that this isn't a new thing for BC Ferries to do ... its been reported that dock fitting has to occur if a vessel is used as a fill in on a route it hasn't operated on in a while.
There's an old quote, that is often attributed to Yogi Berra, but probably isn't actually a Yogism. Regardless its relevant here:
"In theory there is no difference between theory and practice. In practice there is."
And if BCFerries is just being super cautious and basically following what is prescribed in the above quote, than okay. I mean, they have to get the crew familiarized so might as well trust but verify the dock fit in the process.
The following should still be known knowns ... The ride height of the vessel while unloaded. The beam of the vessel. The bow radius of the vessel. The distance from the bow of the walk on passenger gates. etc
Meanwhile, the following should be known knowns in regards to the docks ... The height adjustability of the transfer span and passenger walk on ramps The configuration and angles of the berth The positioning of the wingwalls, dolphins, and other bits of the berthing structure. etc etc etc
Thus, these specs should have already been determined when the vessel was being designed. We've seen reports that BCF has started modified the Long Harbor terminal to better fit the Salish class, so obviously, many of these things have been identified and solutions planned out long before the vessel showed up.
As such, the "dock fitting" should be a quick exercise. Approach the berth, lower all the ramps, check the tie-up positions, and move on.
But they're spending hours at each berth, checking "the fit."
What are they checking? What are the issues? If the vessel doesn't fit, then its either a design problem with the vessel, or the information that BCF should have on hand about the berths is incorrect.
Based on my poor memory of watching BC Ferries berth test the Sidney, Tsawwassen and Burnaby at Blubber Bay on Texada, whatever their process is, it's not a 5 minute thing.
They're very careful about checking clearances of *everything* imaginable, they take pictures of it all and pages upon pages of notes. I'm pretty sure they check for unexpected movement of the marine structures too (possibly more important at Blubber Bay as the 2 main wing walls are pretty old, even back then). Plus sometimes they like to check bow and stern fit so things can get spun around a few times.
I don't know what's all on their check lists, but they seem to have a bunch and they're not short.
Often times when I see a brand new vessel for the first time, I'm not quite used to the size proportions of the vessel. For example the Island Sky and Baynes Sound Connector looked very wide at a first glance. Maybe it was cause I was at Tsawwassen surrounded by equally large vessels, but I didn't quite have that feeling with the Orca. Nevertheless, it's not the width of this vessel that's impressive, it's the height... Salish Orca Docked at Berth 1, Tsawwassen. by Curtis Simonetta, on Flickr
