Dartmouth Ice Festival 2025

It was a cold day in downtown Dartmouth today, which was probably just as well for the 2025 edition of the Dartmouth Ice Festival underway on Portland Street and outside the Alderney Ferry Terminal from January 31st to February 2nd. I've gone down the last two years to try my hand at capturing some of the ice sculptures.


The black & white medium seemed to suit most of these images - I needed to boost the contrast to bring out the features of most of the ice sculpture - although I did process a few in colour.




This bear sculpture is wearing a blanket of light snow from earlier in the day. 






Every time I look at this particular sculpture I can't help but think that ET is making a rude gesture at the record store in the background.




I was fortunate to time this image with the passage of a child in a colourful winter jacket behind the sculpture.



There were several bears.


The lights in the business establishment behind this sculpture added some yellow light to the mix so I kept this one in colour.

Alleyway horse.


Peace sign.


This particular sculpture provided the novel opportunity of capturing the sculptor himself working away behind the block of ice. 

Ultimately, I hope my photographs do justice to the various sculptures that I captured, and many thanks to the sculptors themselves for providing the subject matter! The images can also be found in a gallery on my Smugmug site here

Launch of the future HMCS William Hall

The fourth of six new AOPVs to be built for the Royal Canadian Navy, the future HMCS William Hall, was launched by Irving Shipbuilding on Sunday. I caught her being towed back to the shipyard after launching. Halifax Shipping News has photos of the actual launch process.





Only a week before, the ship was still on land and looking like she wasn't going anywhere fast.





Two slightly modified additional ships (making a total of eight) will be built for the Canadian Coast Guard, once the ships for the Navy are complete.

Foundation Maritime: Salvaging HMCS QUINTE

Commissioned on August 30, 1941, the Bangor-class minesweeper HMCS QUINTE was essentially brand new and had undergone a recent refit in Lunenburg in late 1942 when she ran aground and had to be "beached" - at some point she seems to have additionally capsized and sunk in the St. Peter's Canal. Foundation Maritime deployed to salvage the wreck, but winter apparently set in and the canal froze over before work could begin in earnest.

QUINTE lies on her side in the frozen waters of the St. Peter's Canal. The salvage operation has begun, and righting masts with block and tackle have been set up on the pier to begin righting the ship. This photo looks to the south.

The salvage operation began with the ship up against the sea wall on the east side of the canal entrance. The ship was lying on her port side with the bow pointed to the north, up into the canal.

Looking to the north, a man stands on a gangway rigged from the pier to the wreck. Tackle rigged to the righting masts is already connected to the ship.

The ship is sitting on the bottom in these photos, and her exposed sides and deck would have been subject to the rise and fall of the tides - with all the ice present, this probably contributed to scouring paint from the hull.

QUINTE still on her side, with her starboard lifeboat davits pointing up into the air. The ground is still covered in snow in this image.
The tug that supported the operation at this stage was the Saint-class Ocean Eagle - a Canadian Government asset at this time, and formerly Royal Navy tug St. Arvans, she had been placed under the operational control of Foundation Maritime during the war.

Though ice remains in the canal, snow cover on the ground itself is receding, and Foundation Maritime has managed to maneuver the crane barge Foundation Scarboro into position alongside the now-righted wreck. Operated during the war by Foundation Maritime, the government tug Ocean Eagle can be seen to the right of the image. Foundation Scarboro's shear legs are in the stowed position in this photo - folded down onto the deck on the right side of the barge.

The masts and tackle are still in position after righting the wreck, though she has not yet been refloated. If is hard to tell if the wreck has already been relocated, or if some of the photos have been reversed, because she is now port side-to the pier as opposed to starboard side-to in the previous photos. I am assuming they would not have relocated the righting masts, so I believe this photo is mirrored - the opposite side of the canal in this photo should be the west side.
Once QUINTE was back on a more or less even keel, she was refloated. Presumably Foundation Scarboro's participation would have been critical to this state of the operation.

Now refloated, QUINTE is rafted outside Foundation Scarboro on the west side of the canal entrance, the latter with her shear legs now deployed. Ocean Eagle can be seen in the background. The righting masts can still be seen erected on the east (near) side of the canal.
Apart from the removal of a minesweeper wreck, this end of the St. Peter's Canal hasn't changed that much over the years - the sea wall is still there, and you can see the knuckles in the edge in these Google Map Streetview images to locate the action all those years ago. In fact, the house in the background appearing between the shear legs on Foundation Scarboro still appears in the Streetview image here

A close-up of the now-refloated QUINTE, looking rather the worse for wear after her ordeal. This is the starboard side of the ship, which would have been exposed to tidal action and ice, and presumably the paint has been partially scoured off - although I am unable to immediately find a photo of QUINTE taken before her sinking, so I don't know what her paint scheme would have been - but the camouflage applied during the war tended to consist of lighter colours in order to blend in on the horizon.
After completing the salvage operation in 1943, QUINTE was towed to the Foundation Maritime-operated Pictou Shipyard, where she was repaired by 1944, and then she spent the rest of the war as a training ship attached to the HMCS CORNWALLIS training base in Digby, NS. Although the Bangors had been built with enclosed bridges, it would appear that QUINTE's new training role demanded an open bridge modeled along the lines of the Flower-class corvette, and she appears to have received a new armament outfit as well, at least as compared to her contemporary sisterships.

In 1946, she briefly operated with the Naval Research Establishment in Halifax, but paid off by October 25th of that year. All this might seem like a lot of work for little return, as QUINTE was scrapped in Sydney, NS, in 1947. But then, salt water has a bad effect on electrical wiring, and perhaps problems were beginning to surface - certainly, if her history was known, she would not have been among the first to be purchased by other navies after the war.

The entire incident seems to have been relatively unknown, to the extent that at least one RCN ship historian wasn't even sure that it had occurred - until I was able to produce the photos. And the only reason I myself had the photos was because I was able to access the archives of the Foundation Company of Canada in Toronto, thanks to the kind assistance of Harold Beswick, who combed the archives, collected anything he found of interest and couriered it to me in Nova Scotia, and then received it back when I was finished scanning it. I learned just last week that Harold passed away on April 10th, at the age of 87. So if you've read this and enjoyed it, please say a little thank-you to Harold.

Canadian Ice-breaking

I was having a short discussion on Twitter this week, and discovered that my admittedly limited knowledge of ice-breaking is apparently as obsolete as the Canadian Coast Guard's ice-breaking fleet is.

As noted in a previous post, CCGS Louis S. St. Laurent, the CCG's largest and arguably most capable icebreaker, was commissioned 50 years ago this year. Although she received an extensive refit that saw her outfitted with new engines and a longer bow with a bubbler system, she is reaching the end of her lifetime.

The CCG's only other "Heavy Gulf" class icebreaker, the Terry Fox, is a ship taken up from commercial trade. She also has a bubbler system. Bubbler systems are designed to reduce the friction between the bow of the ship and the ice, allowing the ship to ride up higher on the ice to break it with the weight of the ship. Although newer than the Louis, the Terry Fox is far from young, as she dates from the 1980s.

The CCG's heavy icebreakers are supplemented by a group of "Medium Gulf" icebreakers, the Type 1200 or Pierre Radisson class. With Pierre Radisson herself built in 1978, she is older than Terry Fox.

The dedicated icebreaker fleet is supplemented by a fleet of light ice-breaking aids-to-navigation tenders. I believe these ships are fairly conventional as icebreakers go.

CCGS Edward Cornwallis is one of a class of Type 1100 light icebreaker / major navaids tenders.

Earl Grey is one of two Type 1050 medium navaids tenders / light icebreakers.
All of these ships have a conventional arrangement of shafted propellers, and are intended to break ice with their bows in a forward direction.

The state-of-the-art in ice-breaking has changed, though. Newer designs incorporate azimuth thrusters, and many are designed to break ice with their sterns, and moving backwards through the ice. Even the fancy bubbler systems in "newer" Canadian Coast Guard icebreakers are now at least partially obsolete, replaced by modern paint coatings and the lubricating effect of the azimuth thrusters.

In response to some posts on Twitter between myself and Dr. Samuel McLean, Aker Arctic (their website features a video of one of their designs breaking ice in an aft-sideways direction) was kind enough to chime in with some expert information. The Twitter thread follows.





The shape of the icebreaker pictured above can be seen here, although good luck reading the text (you might have to get your browser to translate for you).




So there you have it - apparent even from this short thread, ice-breaking technology has moved on considerably.

The CCG's future heavy icebreaker, the John G. Diefenbaker, will be fitted with two conventional wing shafts with a single azimuth thruster in the middle - from the look of her, she is designed to break ice with her bow, and she will also be fitted with a bubbler system as well as two bow thrusters. Interestingly, Aker Arctic is a member of the design team. 

Although initially intended to incorporate azimuth thrusters for breaking ice going astern, the Navy's new HARRY DEWOLF class of Arctic/Offshore Patrol Vessels (AOPVs) are being built with conventional shafted propellers (with a bow thruster) to allow ice-breaking by the bow. I have no information to suggest whether they have been built with a bubbler system, but perhaps the bow thruster can help with that.
