More details on the history (and the sinking) of the MT6

I learned more of the history of the MT6, which is sunk in Elliot Bay, from the Puget Sound Maritime Historical Society.

Rather than try and retell it’s life story I capture some quotes from that organizations monthly journal here: 

Formally the Tacoma, it was “a ferry that took trains across the Columbia River 100 years ago.”  “She was the reliable workhorse that the Northern Pacific Railway Company needed to complete its transcontinental service from Duluth, Minnesota, to Puget Sound.”  “The massive railroad ferry became an icon for [the town of] Kalama, her home port.”  “A product of the industrial revolution that crossed the Atlantic, Tacoma brought a mammoth representation of 19th century mechanical engineering to a fledging corner of North America.” 

“The Northern Pacific Railway Company contracted with Harlan and Hollingsworth Company of Wilmington, Delaware, to build an ‘Iron Steam Transfer Boat’ for the staggering price of $400,000.”  “The vessel was completed in the summer of 1883.”  At the time, she was, “the second largest ferry in the world.”  

“February 1884: The ferry package in labeled boxes, arrives in Portland, in 57,179 pieces.”
“October 1884: The ferry carries its first freight cars”

1903: “President Theodore Roosevelt’s tour of the west, which included… a whistle stop in Kalama on May 22, undoubtedly entailed ferrying the presidential train across the Columbia River on Tacoma.”  

“In 1908, after 24 years of service” supporting the booming rail transportation industry, “the iron transfer boat was no longer needed.  The railroad bridge across the Columbia River at Vancouver, WA, was completed… and the Tacoma made her last run on December 25th

“In 1909 she was [re]assigned to transport rock to build the North Jetty at the mouth of the Columbia River” 

“Milwaukee Railroad purchased the vessel in 1917 and towed her to Puget Sound, where she was stripped down, renamed Barge No. 6, and used to transport railroad cars across the Sound.”

“In Seattle’s Elliot Bay, on the morning of January 1st, 1950, the 6000 ton freighter Fairland was trying to avoid a tow of logs.  She collided with the Milwaukee Barge No. 6 (formerly Tacoma) that sank in 20 minutes.  Her crew of four were rescued by the tug Sandra Foss.  There were 19 railcars aboard her – of which 15 were loaded with lumber.  Six of these broke loose and floated ashore where they could be recovered.  They were lifted aboard another rail-barge by cranes from the Foss Company who had the salvage contract.”

Multi-Beam Imaging of Elliot Bay

After the February 2001 earthquake in Seattle, NOAA and the USGS teamed up in a project to map the underwater geology of the Duwamish River delta (Elliot Bay, Seattle), the Puyallup River Delta (Commencement Bay, Tacoma) and the Nisqually River delta.  The multi-beam images they created are really interesting. 

The one I will attach with this entry is of Elliot Bay, but I modified the file a bit to highlight points of interest:

The dotted line across the image is the major fault line that runs under the bay and then up through downtown Seattle.  The sharp ridges you see on the west side of the dotted line are very pronounced faults – I have seen them with my own eyes on prior dives in this area.  But until this image was created I had never known where they connected on the other side of the bay.  Turns out they line up pretty well with Pike and Pine streets in downtown Seattle.  When the ‘big one’ happens, it is going to be devastating. 

Two of the circles on the north end of the image highlight some pretty big shipwrecks, both of which are in more than 300 feet of water.  Date of sinking, names of the ships, etc all unknown.  I’ve also circled a crater which looks very large.  It seems it was likely caused by a significant amount of ordinance – maybe during WWII.  I also circled in the NW corder of the bay what appears to be an unexplored wreck in shallow water.

The circles on the south end of the image are of three wrecks I have written about on this website, the MT6, the AJ Fuller & the Astorian.

Back in the water

I was back in the water last Sunday after a long break.  I made a scooter run at Alki with friends.  It was a typical training dive for us; what we do in between the ‘big’ dives.  
We traveled out about 3000 feet with the average depth a bit more than 100ft and a total run time of about an hour (with deco). Pretty short dive.  Along the way we made deco bottle drops for ourselves and the team behind us that was planning to push quite a bit further.  We also made a stage drop for them at the 3000 mark before heading home.    
On the way back we ran an ‘out of air’ drill – which involves donating your breathing gas to your buddy, switching to your back-up, stowing your scooter and then getting into a tow position so the two divers can situate themselves as one long diver inline behind one scooter.  We also ran some valve drills while in the shallows just before deco.  
All in all a good refresher dive.

AJ Fuller – Redux

Made another dive on the AJ Fuller today – but this one ended up being a pretty short event. 
There were four divers including myself and we were broken into two teams.  We descended to the bottom in about 3 minutes, but this time the shot ball from our descent line was sitting on the wreck, so our bottom depth was 220ft.    

The first team had already tied in a reel to the line and were out in front of us by a couple minutes.  My partner and I were running parallel to each other and on opposite sides of their line.  We made our way from the center of the ship to the outside beam.    

On reaching the outside beam of the Fuller, I looked over to see my partner’s scooter doing its best to drag him over the edge of the ship.  Its main compartment seal had failed and the scooter was completely flooded – this made the scooter weigh a good 50lbs.  Having a 50 pound negative weight attached to you isn’t a great way to make your way around at 220ft, so we thumbed the dive and headed for home.  Just before our ascent my buddy unclipped his scooter and tied it in to our up line so as not to have to deal with the negative weight.     
By the 25 minute mark we were back at the surface for a dive that normally has a run time closer to 90minutes.  The visibility was so bad on the bottom the other team, one of which was shooting video, called their dive short as well.    

With the total amount of gear we take along for a dive like this, there are lots of opportunities for problems.  So when things do go wrong we just learn to deal with it.  The AJ Fuller isn’t going anywhere soon, so the only thing you can do is take it in stride.

AJ Fuller

I made a dive on the AJ Fuller with SCRET.org today. The Fuller is a massive 229 foot long, three mast sailing ship that sunk in 1918.  The AJ was owned primarily by Flint & Company of New York, and named for a shareholder who lived in Bath, Maine.   The three-skysail yard ship was one of a dozen ‘Down Easters’ built in 1881. Under the Flint house flag she sailed between New York, San Francisco, and Liverpool for ten years. 

In 1892, she was put in trade from East Coast ports, where she loaded case oil for the ‘Orient’ or general cargo or coal to Hawaii, generally returning with sugar cane.  It was while she was in that trade that Felix Riesenberg, who later became a master mariner in his own right, sailed in her before the mast.

She was sold to the California Shipping Company in 1902 and used in trade between the Pacific Northwest and Australia, exporting lumber and importing coal. In 1912, she was purchased by the Northwestern Fisheries Company of San Francisco, who employed her in their seasonal salmon fisheries—sailing north in the spring with fishermen, cannery workers, and supplies, and returning in the fall with a full load of canned salmon.

On October 18, 1918, while inward bound to Seattle in a heavy fog, she was rammed by the Japanese steamship Mexico Maru and sank in about 240 feet of water.

I was on a team of three divers and there was one other team of two.  Our team was first in the water, which meant once on the bottom it was our job to locate the wreck.  We thought we dropped the anchor ball and buoy line right on top of the wreck – or we at least hoped that was the case. The visibility was incredibly great on the way down.  I really thought there was a chance we would encounter the same viz on the bottom, but we weren’t so lucky.  Around 170 feet it clouded up pretty badly and stayed that way the rest of the way down.  Since the wreck rises about 20 feet off the bottom, we expected to encounter the Fuller on our decent at a depth of about 220ft.  But we went right past 220ft and found ourselves hovering above the Puget Sound’s floor in 248 feet of water.  That is the deepest I have ever been.

We tied in a cave reel to the anchor ball and buoy line and set off looking for the Fuller.  With only 2-3 feet of visibility it took us 5 minutes to find a wreck that was really within 20ft of where our anchor ball hit the ocean floor.  Once on the wreck we encountered plenty of life.  Lots and lots of big shrimp – some big lingcod too that startled off so quickly they made the already bad visibility worse.  We were on scooters, with the lead diver running our cave line and the other diver shooting video.  I was in the number two position making sure the diver running cave line didn’t encounter any problems with that line.  Cave line has a way of being evil at depth.  We passed over China plates and tea cups, errant old bottles etc., but since this wreck is one of only two wrecks on the list of Washington’s historical sites we left what we saw undisturbed.  

At 20 minutes into the dive we ran out of line on the cave reel.  That meant we had covered around 400feet.  We cut the line and I tied it off.  Then we stayed on the scooter triggers back to our up line.  We started the ascent at 25 minutes. 

Decompression was uneventful, though long.  It took around 65 minutes to step our way back to the surface.

Al-Ind-Esk-A-Sea

Our dive on the Al-Ind-Esk-A-Sea, or “Big Al” as we like to call her, is complete.

With a history that includes everything from being a Cruise Ship, a US Navy Ship and a private yacht, the Al-Ind-Esk-Sea floated her last days as a fish processing ship – owned by TransAlaska Fisheries Corp.  You’ll read in the scret.org link that she was capable of processing and carrying more than 5 million pounds of packaged seafood in her refrigerated holds.  This freighter has a beam of 50 feet and is more than 300 feet long.

In 1982, 23 years ago this month, Big Al was at anchor in Port Garner undergoing repairs when a fire started on the ship. Due to the 18 tons of ammonia on board (used in the ships refrigeration system), fire fighting crews stayed away from her.  She burned for two days and then rolled on her side and sank to the bottom of the bay.  She now rests on her starboard side, 240 feet below the surface, just a half mile off shore.       

Our dive operation on Sunday consisted of two teams of 3 divers each, 2 safety divers and our captain Troy of Porthole Dive Charters.  I was on the first team of divers, and after hooking the wreck while above water, our first goal for the dive was to free the grappling hook, then carry it to the top and set on the port side of the wreck.  Completion of this task would enable us to retrieve the grappling hook at the conclusion of the dive – once everyone was back on board.  Once the grappling hook was sitting on the top of the wreck and free of obstruction, we planned to explore the wreck using our Gavin scooters then terminate the dive at a run time of 20 or 25 minutes.  

The first task turned out to be a pretty hairy experience: we found the grappling hook on the bottom, near the 240ft mark, and it was stuck in the mud.  The hook weighs more than 20 pounds and the only way to get it out of the mud was to grab hold of it and inflate the buoyancy control wing just enough to pull it free.  My friend took on this task and on the release of the hook from the mud two expected things happened: 1) a cloud of slit significantly reduced visibility and 2) the inflated wing pulled him rapidly upwards about 10-20feet.  In this process something unexpected happened.  All three of us rose up underneath an almost invisible spider web of old fishing line.  It was an unnerving 5 minute process, sitting at a depth of about 220 feet, to cut ourselves free of this underwater killer, and if we hadn’t kept focused it might have meant death for anyone of us.     

After the fishing line incident, we all signaled that we were still ok and with 15 minutes of bottom gas left to burn we set out on the scooters.  We followed the port side walkway railing from mid ship to the bow.  Riding just off this railing would have made for a photo like you would expect to see on a National Geographic video of the Titanic.  At the bow we encountered the enormous eyelet that housed the anchor chain and the big spools that had anchor chain wound around them.  We then circled back towards the mid section, taking our time looking at the deck of the ship which loomed like a 50 foot wall on our right.  Eventually we made it back towards the stern and the super structure of the ship, moved again to the top and finally back to our grappling hook sitting free and clear on top.  Bottom time was reading 20 minutes at that point, so we circled OK, gave the thumbs up sign and began our slow 60 minute decompression ascent back to the surface.    

For the dive we used a bottom mix of 15% oxygen, 60% helium and then 50% oxygen and pure O2 for decompression.

MT 6

Plans changed a bit for our dive on the AJ Fuller.  We had Coast Guard clearance to be diving in the area, and we were in contact with them through the vessel traffic system (VTS), but when we got out near the target site there was an 800 foot long container ship anchored right over our planned area of operation.  We sat and waited for an hour or so for the ship to move out of our way and into its berth at Todds Shipyard – but then in an updated radio communication with VTS we learned we would need to wait for the container ship to move out of the way, and then wait for another to come & go before we could “commence our operation.”

So we bailed on the AJ Fuller and moved from the East Channel entrance to the West Channel entrance for a dive on the M.T. No 6.  We don’t know a lot about the MT6, other than it was a train ferry converted to a barge and that it sunk on December 31st, 1949.  NOAA took a side scan of this one some years ago and the target location is visible on most NOAA maps of Elliot Bay.  It is also visible in the multi-beam image of Elliot Bay that I have posted on this website.

The depth of the wreck and our dive was 220ft.  We spent 25 minutes on the bottom, about 10 minutes getting up to our first gas switch and then 50 minutes in a stepped decompression to the surface.  Because of a tidal flow that occurs at depth on this wreck we brought scooters – and because of the depth and the time we would spend on the bottom we brought both 50% oxygen and pure oxygen for decompression gas.   

There was lots of life on the wreck, saw one ling cod that must have weighed 60 lbs.  We tied in to our drop line with a reel of cave line, and then ran a full loop around the wreck which turned out to be around 400ft (wreck is 150ft long by 50ft wide).  It’s a big wreck to see and by the end of our 25 minute dive we felt like we had just scratched the surface of it.

AJ Fuller

This Saturday I’m going out with the normal crew to make a dive on the AJ Fuller – a massive 229 foot long, three mast sailing ship that sunk in 1918.  She is sitting at the bottom of Elliot Bay, 240 feet deep, so I consider this dive to be a “big dive” if that makes sense. 

The AJ was owned primarily by Flint & Company of New York, and named for a shareholder who lived in Bath, Maine.   The three-skysail yard ship was one of a dozen ‘Down Easters’ built in 1881. Under the Flint house flag she sailed between New York, San Francisco, and Liverpool for ten years.

In 1892, she was put in trade from East Coast ports, where she loaded case oil for the ‘Orient’ or general cargo or coal to Hawaii, generally returning with sugar cane.  It was while she was in that trade that Felix Riesenberg, who later became a master mariner in his own right, sailed in her before the mast.

In 1912, she was purchased by the Northwestern Fisheries Company of San Francisco, who employed her in their seasonal salmon fisheries—sailing north in the spring with fishermen, cannery workers, and supplies, and returning in the fall with a full load of canned salmon.

On October 18, 1918, while inward bound to Seattle in a heavy fog, she was rammed by the Japanese steamship Mexico Maru and sank in 240 feet of water.

Alki Plains Line Project

The last month and a half I’ve been diving with the aplponline.org group making extended range dives on DPV’s (diver propulsion vehicles), a.k.a. ‘scooters’. 
Starting at Seacrest Cove 2 (off Alki) we have more than 7000ft of cave line run at an average depth of 110ft.  The round trip is nearly 3miles.  Pretty incredible dive to make/distance to cover at that depth.  

The goal has been to get proficient at laying cave/wreck line while running scooters, repairing & working with loose line (dealing with entanglement hazards, etc), improving communication and line protocol and active training for bigger/deeper dives.

The last dive I made out there we had a great encounter with two harbor seals.  They were being so friendly and curious… checking us out and brushing up against the scooters – it honestly looked like they thought the scooters were other seals.  After disappearing for awhile, one seal came up behind me and nipped one of my fins – which gave me an adrenaline jolt based on the number of shark encounters we experience in this area as well.   

It’s been fun; but I am anxious to get back out in the lake to see and possibly find more historical wrecks.  More on those efforts to come…
