What does the "DEV" prefix stand for in DEV Galena? I believe it means 'Diesel Electric Vessel'. I guess we have a few ferries around that could go with the same prefix. That's what I was thinking too, but then I thought, "No... it can't be that since a lot of other ferries have the same engine configuration, but have the prefix Motor Vessel."

Stupid question: Is the DEV Galena a hybrid ferry? The DEV Galena is 40 years old. No, nothing is hybrid at all about her.

Doesn't the DEV Stand for Diesel Electric though?

Doesn't the DEV Stand for Diesel Electric though? It probably does, but it does not mean that the vessel is hybrid. I'm pretty sure it is some kind of propulsion, but I'm not sure. For example WSF's Jumbos, JMIIs, Supers and Evergreens are all marked as Diesel-Elctric (AC) for their propulsion type, yet they are not hybrid ferries. Perhaps Barnacle or EGfleet could explain this to us.

Doesn't the DEV Stand for Diesel Electric though? Yes, it is "Diesel Electric Vessel." A lot of ships are Diesel Electric, but only some choose to use that "DEV" as their prefix. I'm not sure why the DEV prefix is so uncommon for diesel-electric ships.

I'm not sure why the DEV prefix is so uncommon for diesel-electric ships. There isn't really a lot of regulation with the use of ship prefixes. Generally, they just refer to the use of the ship or it's general means of propulsion... it's not really necessary to distinguish whether a ship is directly driven or diesel electric or turbine electric. This wikipedia article has some decent information. en.wikipedia.org/wiki/Ship_prefixTo attempt to answer Solduc's question... the term Diesel Electric refers to the method of propulsion. With DE propulsion you have one or more diesel engines driving a generator, creating electrical energy. That energy is transmitted to an electric motor, which drives a propeller. You can do various things with the electricity before it gets to the motor to provide better control and thus better maneuverability. The "AC" in the case of the JMII's etc refers to the fact that the generators create Alternating Current electricity, similar to the power in your house. The old SE's used a DC system, which was simpler but not as efficient. The term hybrid refers to a system where there is more than one source of propulsion energy. In the case of the Hyak's proposed system, this will come from battery banks that will supply power in low-demand situations.

This wikipedia article has some decent information. en.wikipedia.org/wiki/Ship_prefixIt depends on who you talk to as well. A friend who used to work on BCFerries during the summers when the V's were just being stretched liked to joke with passengers about the differences between a Motor Vessel, and a Ship. Something about them not having proper ship structures, especially at the bow and stern where they have doors instead of hull plating, doors which actually open into a very large, very open and not very watertight space which a true ship would have. But, the term Motor Vessel is often used of ocean going ships, as well, but many ocean going ships are now motor driven as well, and there are different classes of ocean going ships which might still be called Motor Vessels. With most BCFerries vessels, the prefix MV is really an indication of the fact that they are primarily propelled by electric motors which turn the propeller shafts, and not the actual diesel engine itself. The Tsawwassen was the last direct drive vessel BCFerries had, but some of the older Blackball ferries were probably direct drive, with the propeller turning directly off of the engine shaft, or a shaft geared to the engine. Even now, mostly all the BCFS and WSF fleets would all be referred to as motor vessels, but they are still classed differently, with many of WSF ferries being restricted to sheltered waters, while most of BC's major vessels are specifically certified to cross open waters. Sorry Mill Bay, but respectfully, this post is full of crap. Your friend is semi-correct, in that any ship used as a coastal ferry is not built to the same degree of construction as an ocean going ship. The same reason a Hummer you buy at the local GM dealership isn't the same as the HumVee the Canadian Forces take into Afghanistan - they're built for completely different purposes and stress levels. The term "ship" is a generic term. There's nothing technical about it. A "ship" is not different from a "motor vessel", as a motor vessel is a type of ship. Nothing more. The term motor vessel comes from the fact that the ship is driven by diesel engines, and not steam engines. It has nothing to do with being diesel electric. BC Ferries currently owns two classes of diesel electric ships: The Coastals and the Cap/Cumbie. All the others are direct drive diesel. Also, the only BCF vessels capable of being certified to travel open waters are the NorAd and NorEx. The rest all have restrictions based on their construction to near coastal voyages. While I'm by far not an expert, I'm a 3rd year marine engineering student with a background in mechanical engineering. I guess that means I know just enough to be dangerous

This difference of opinion reminds me of a conversation I had with a life long deep sea mariner years ago on Saltspring Island, who practically spat in disgust when I referred to the Queen of Tsawwassen as a ship. "That tub's a boat", was his assertion.
Mill Bay's ruffled hackles notwithstanding, I tend to defer to people with experience or training in nautical tradition when it comes to terminology, so Nick's perspective here is worthwhile.

DEV Galena arriving at Shelter Bay BC, in the morning of September 10, 2013. - Seen by me on a fabulous day of Arrow Lake ferry riding. VIDEO compilation: ================= Still photos: 8:45am arrival, with the morning low-cloud on the lake. With the idle MV Shelter Bay. (DEV Galena starts work at 5:00am, MV Shelter Bay starts work at 9:00am) 10:55am, just before I boarded her:

Awesome video. Looks like you had a beautiful day for ferry riding on the lake. This is such a scenic route and Shelter Bay is a neat little area for a ferry landing. I love how you can walk out to the point there. One of my second favorite inland ferry routes. So how many trips on those ferries did you do on that route??

So how many trips on those ferries did you do on that route?? I stayed at Revelstoke the night before. So in the morning, I drove down to Shelter Bay, and parked my car at the rest-area beside the ferry landing (a small parking lot that is beside the top of the ramp-hill). As a foot passenger, I did 1 round-trip on each of the 2 ships. Then, I got into my car, put it in the line up, and drove onto the DEV Galena for my car-crossing. -------------- In the next video that I post (it's currently uploading to YouTube), I show my footage from the MV Shelter Bay, which is the first ship that I rode on that day. The morning weather then was lots of low cloud over the lake, and you couldn't see the mountains. - by the time we were heading back to Shelter Bay landing on my first round-trip, the clouds were starting to clear out.

My final video from Upper Arrow Lake. - this is shot from aboard the MV Shelter Bay. It includes views of DEV Galena as she passes by.
September 10, 2013.
I can't say enough good things about the people at WaterBridge Ferries who allowed me access to various areas of their ships, in shooting these videos.

Because you can never have enough in-service photos of a soon to be retired or moved ship, here are a few more of MV Shelter Bay (ex MV Needles) on Upper Arrow Lake on September 10, 2013. Leaving Shelter Bay, BC Photos taken from DEV Galena ferry: - his part of the Columbia River is sure different looking than MV Sanpoil's territory. Taken as we approach Galena Bay terminal.

A few onboard photos of the Diesel Electric Vessel GALENA, from the morning of September 10, 2013. The essentials: - The bell says "MV" not "DEV". That's an interesting quirk to the whole DEV uniqueness of this ship. The bridge: I like this angle, especially because I experienced a round-trip up there. ------------ More DEV Galena photos to be posted, in the days/weeks ahead. - this thread will be a great legacy for this ship on this route.

I note the quotation marks around the instructions printed on the bridge deck. I have to wonder if this was an exact quote that was at one time delivered to a misbehaving motorist by a stern crewman, preserved for the education of any subsequent trouble makers.

Scenes from the rocky viewpoint at the Shelter Bay ferry terminal. - this is next to the rest-area parking lot. As the vessel is approaching the berth, this area is the cliff to the right. from morning of September 10, 2013. Here are 2 photos that show how the low clouds clear out in the morning, with the MV Shelter Bay in her moored location: 8:20am 8:45am ------------------- The morning shuttle of the MV Shelter Bay's crew to the ship, by way of the DEV Galena: -------------- MV Shelter Bay moves out of the mooring area, and heads for the Shelter Bay dock. - the master told me that if he'd known I was filming, he'd have sailed between the pilings instead of going around the outside.

One of the things that caught my eye with DEV Galena is the vehicle ramp at either end of the ship, and how it looks like it is part of the hull, but that it actually rides above the water. The actual water contact point of the bow & stern are "inland" a bit, close to the end of the white-stripe of paint on the side of the ship. So those tapered ends to the ship really are the ramps and they are quite longer than that of the MV Shelter Bay. And I will call them "Fixed, on board ramps" because they don't get pulled-up like the ones on the Kwuna. Here's what I mean: The end of the hull is near the "GALENA" name painted on the side, at the end of the white-stripe. - in this photo, you can see that each end's ramp is above the water, and you can see how long they are. Here's the view of one end, on an angle. - you can see that the hull cuts the water near the "GALENA" name paint. And this on-board shot shows the ramp area - you can see how the ramp area isn't used for vehicles (although I've seen motorcycles there, and have seen the front axle of a truck encroach a bit there) - the back end of that silver station-wagon is probably the start of the above-water ramp portion of the ship. - photos are from September 10, 2013
