im going to point some things out right now. even though there are no REPORTED incidents, does not mean these things don't happen. im betting incident similar happen close to 5 times a year, PER VESSEL, with incident now being defined as an anomaly in the propulsion / control unit. something as simple as the vessel not reacting to a particular situation, or a drive unit set to point at 45 Degrees, instead pointing at 43 degrees, therefore causing the operator to have to re adjust. im not saying the technology is perfect, but the incidents are probably commonplace, but never to the severity of the vessel misinterpreting a slow ahead @ 38 degrees to a full ahead @ - 38 degrees
Whatever the difference in loading and docking between Europe and BC, it's not due to tides, as the biggest port in the UK, Dover, has tide ranges similar to Tsawwassen. Some places more, some less. St. Malo has tide ranges we would never see here.
As an aside to this accident, I wonder what the fuel saving might be if ferries were actually just held in place by rope only, instead of also being pushed in, especially on runs like Denman and Hornby, where in non-peak times, the boats are sitting at dock for forty minutes out of the hour.

Anyone know what they mean in the following:
11. While in dock and loading and discharging, evaluate all BCFS RAD vessels to determine if JOG steering should be engaged prior to clearance to discharge and remain until clearance to sail is given. If adopted, this procedure should be included in the Vessel Specific Manual.
Other than that, I think the report is pretty clear, and spreads the fault across both the company and the crew. I could see Scenario 2 being very feasible.
It is a non follow up control used for positioning the RADS. It is mainly used if you must split control for the two units on one combinator. It can also be used as a secondary control if you lose the main. Each RAD is fitted with one on the W/H console.

Nanaimo Bulletin news story re Quinsam safety upgrades.
More upgrades still needed on Gabriola ferry
By Darrell Bellaart the news bulletin Aug 23 2007
Safety improvements on the Gabriola Island ferry aren’t as far along as recently stated by B.C. Ferries.
Alarms to warn of problems with the right-angle drive units used to steer and propel the ferry linking Gabriola to the Nanaimo harbour have yet to be installed.
Nor have heavier cables been installed on all such ferries, to prevent them unexpectedly pulling away from the dock, if something goes haywire with RAD steering/propulsion units.
Those are among the recommendations made in a safety review conducted after a man’s pickup truck plunged into the drink at the Nanaimo-Gabriola dock near Cameron Island Jan. 26.
The accident happened when the ferry suddenly lurched away from the dock, just as Randy Nicifore was driving aboard the vessel.
An investigation resulted in several possible causes for the accident, including distraction of the ferry operator by a telephone call or a malfunctioning drive unit. For safety, investigators recommended putting alarms on all RAD units to warn operators if they malfunction.
Deborah Marshall, B.C. Ferries spokeswoman, said last month Ferries had “closed off” on 13 of 16 safety recommendations, including the RAD alarms, but that statement was based on wrong information.
“What we’ve done, we’ve worked with the manufacturer on a design for the alarms,” Marshall said.
And instead of replacing cables used to tether the ferry to the dock until loading is complete, Marshall said they have been tested.
“We’ve done inspections fleet wide, now we’re doing an analysis, calculating the reflex action of the cables,” Marshall said.
“Rest assured all cables throughout the fleet have been checked to make sure everything is as it should be.”
Marshall couldn’t say how long it would take B.C. Ferries to fully meet the recommendations. She said ferries is now in the process of installing voyage data recorders on all vessels during refits, and that could take up to 18 months. =======================
Ive got to say thats a Crock of SH*T. This Cables could NEVER hold that vessel in the event of a steering malfunction. its only ment to hold the vessel if the vessel looses power, unless they've changed the cables...
