A (Very Heavy) Step Back in Time

I've always had a fascination with hard hat diving, ever since I was a little kid. Who hasn't? Walking along the ocean floor, peering through thick latticed windows, the hiss of air bubbling through green water - it's the same dream our great-great-grandparents had. The North East Diving Equipment Group puts on several vintage dive rallies where they invite folks to try out hard hat diving for themselves, and they didn't have to ask me twice. There is no fee, all they require is that you listen to a briefing, and then assist gearing up divers a few times. This weekend's festivities were at Brownstone Park near Hartford, a beautiful flooded quarry that only recently opened. It's not very big, and it's not very deep, but it's still a very pretty place to spend the day. Surrounding the lake are sheer brownish-purple traprock walls, with rock climbers top-roping on the far walls. To my surprise I ran into Jerry Milmoe, whom I had taken my prism training with years ago, and whom, with his brother-in-law Ruben, I last bumped into on a boat in the middle of the St. Lawrence. Both of them were here to try the helmets out for the first time as well. Another surprise was Martin Weber. Stephan and I dived with him in Cape Ann last year, after I had met him on a trip to Honduras. So just because Brownstone is small, and tucked in next to diesel storage tanks, doesn't mean its not a nexus of the Northeast diving community!

I recently bought a pre-war Dräger dive helmet, or rather Draeger, those crazy Germans can't make their minds up when it comes to umlauts. It isn't diveable, but the kids love playing with it (see? another generation dreams!), so the whole fam damily joined Stephan and me for the trek.

For today we used Bob Rusnak's US Navy Mark V helmet and rig. This venerable design was born in 1905, and stayed in service all the way until 1980. It has a com-link with the surface, a chin-operated purge valve, and a spitcock to allow a little water in (useful for clearing the windows if they fog up, or taking a drink if in fresh water.) The helmet is mounted to a collar, which in turn is bolted into the suit. In order to gear up, you first slip into the rubberized canvas drysuit through the neck hole, then slide your hands through the thick rubber wrist seals. As a diver that is about the extent of your participation in the process, the rest is done by the support team. Brass boots are tied on, 17 lbs. each. There are brass grommets along both calves to prevent air going to the boots in an inversion (which you are NOT going to tuck and recover from), but for today we left them loose. The collar is inserted into the suit and secured to the rubber gasket with 12 brass t-nuts. A weight harness is then belted on, a two-man job as it weighs 70 lbs. The helmet is carefully slipped over the diver's head (at least in theory - hope that nose is okay Jerry), bayonet-locked, and the air and communication lines tied into place. Once we had a rhythm going we could get the diver set in 10-15 minutes without any rushing, something you never want to do with gear this heavy. All told the configuration we had was about 180 lbs. This is not the time to find out if you are claustrophobic, because if you are, you will be freaking out. You also need to be comfortable with putting your life entirely in the hands of other people, and to have complete faith in equipment with single points of failure. That is pretty much the antithesis of everything I am about when it comes to diving, I go to great lengths to avoid letting any piece of gear, or any person(s), have that degree of control. When it comes to hard hat diving though, the ante is to just put that attitude on the shelf.

I was a little concerned, as the first diver had seemed none too happy, and came back out pretty damn quick. He was a big guy, but the weight of the gear really bothered him. I need not have worried, when I stood up and walked to the water it was all very manageable, with the help of my support team. A safety diver accompanied me in a SuperLight, which as its name implies is a much less cumbersome, more modern dive helmet. The pinch-and-blow Valsalva manuever is out, so it pays to be on friendly terms with your Eustachian tubes. I am, and a few jaw wiggles and gulps later I was fine to descend. Entering the water was much different than I'm used to. I felt the water go up my chest as normal, but then there was no sensation of immersion when the water closed over the helmet, and I looked up in surprise to see I was in 10 feet of water already. As is too often the case for me lately, normal also meant getting wet, as water flowed through the right wrist seal with gusto. Good thing it was warm. Air flow is controlled by a knob at your left side, and is rather noisy. For a moment I shut it off, and enjoyed pure silence, the only sound the throbby resonance of my breathing inside the helmet. It reminded me a bit of narcosis, that sensation of being disembodied and remote. Buoyancy is controlled by adding more air, and an experienced diver can ascend and descend easily through open water. I, on the other hand, stumbled about with all the grace of the Tin Man on a week-long meth binge - at one point I thought I might even lose a boot in the muck! I'll leave the effects on the viz to your imagination (put your head in a brown paper bag - yep that's it.) I also uttered several brilliant and incisive observations (ex: "this is so fucking cool!") before remembering that the com link was sharing my witticisms with the world. Oh well, Neil Armstrong's second comment on the moon had to do with oral sex, so there's precedent. I was surprised later to hear Barb come over the com-link, resulting in many jokes about husbands fleeing to the bottom of the ocean but still trailed by their wife's voice. I took the high road and exclaimed just how wonderful it was to enjoy the two loves of my life at once (did you know Barb can snort and guffaw at the same time?)

Too soon it was time to turn the Slog (Dive just doesn't seem an appropriate word for it), and I followed my umbilical back as it snaked along through the weeds. Gravity is not your friend when you are wearing 180 lbs, so I leaned forward and transferred some of the weight from my lower back to my legs via my arms. It was effective albeit undignified: in the video Barb shot I look like nothing so much as an 80 year old man who has just crapped himself. I later slipped into my Meg and shadowed a diver in a SuperLight, despite the no-solo-diving-rule (heh heh stealthy rebreather.) Well before I could see him I could clearly hear the chatter over his com-link.

Many thanks to Ray, Bob, and all the guys and gals at North East Diving Equipment Group. You'd be hard pressed to find a more friendly and generous bunch. I can see doing this again and again and again...

Scapa Flow May 2007


note: there are several dozen pictures from this trip, in an album at http://www.wreckvalley.com/gallery/v/world/Europe/Scapa+Flow/

UK divers have it good. Really good. Wrecks everywhere, dive sites everywhere, and then, for a change of pace, nip up to Orkneys for the cream of the Kaiser's Navy. It's the good life, and I got to share it for a week. Our original destination was the U-92 and the U-102, First World War submarines in the North Sea that were only discovered last year, and have yet to be dived. Mother Nature had other ideas though, so as a consolation prize we spent the week diving the German High Seas Fleet in Scapa Flow.

Scapa Flow is a natural basin, 15 miles in length and 8 miles wide, with an average depth in the 130' range. During both World Wars it was the home to the British Navy, providing protection from both the elements and the enemy, as well as access to the North Sea and Baltic. The armistice at the end of World War One was basically a cease fire, while that highly flawed document, the Versailles Treaty, was drafted. Under the terms of the Armistice the German Hochseeflotte was to sail to Scapa Flow for internment. There it languished through the long winter and spring, with the crews becoming more embittered and even treasonous, having been thoroughly penetrated by the Communist party (the commander actually had to flee his flagship!) The peace talks clearly pointed towards a vengeful Victor's Peace, and the grim prospect for Germany that, with the Hochseeflotte in their possession, the Royal Navy would be unstoppable. The culmination of the all these tensions was that, on June 21st, 1919, Admiral Ludwig von Reuter gave the order to scuttle the entire fleet. Out of 74 ships, 52 sank completely, with the balance being either grounded or seized by Royal Navy boarding parties. During the next several decades the overwhelming majority were raised for salvage, the largest such project ever attempted, and an amazing story in itself. In one of life's little ironies, the steel thus recovered was sold on the open market, where a significant portion of it went towards re-arming Hitler's Germany - Mark Twain would have loved it. What is left is 14 German warships, as well as an enormous number of Blockships, so called because they were used to block submarine access to the Flow through various sounds (perhaps Barndoor ships would have been more fitting, since they were placed after the U-47 had snuck in and wreaked havoc.) The same topography that made this a brilliant harbor for the Royal Navy makes it ideal for diving as well, with all sorts of shelter from the ever-present wind.

But first I had to get there. I took an 8 pm flight from Newark, changed planes in Edinburgh, and I was in the Orkneys by 11 am the next day. British Airways gave me a minor coronary by sending my bags on the evening flight, and my cab nearly ran over a pedestrian on the ride in ("Everyone knows I'm a mad bugger!"), but really, it was a piece of cake. I deliberately came a day early, which was well spent enjoying Kirkwall. The 12th Century St. Magnus Cathedral dominates the town, with a 14th Century Renaissance palace across the street. The Orkney Museum is here as well, covering 5000 years of human presence in the islands. Neolithic carvings, Pictish art, all the way to modern times, it is impeccably curated. Flanking every window in the streets of Kirkwall are two small holes, which are used to board up the windows for the Kirkwall Ba. This event, the Middle Ages predecessor to football, is played using the entire town as the field. Massive crowds from each side (Uppies and Doonies) battle it out all day long, up and down the streets, through houses if need be, to put the ball in their respective goals. There was even a Women's Ba, Christmas Day 1945 and New Year's 1946, but it was not repeated as it was deemed too violent! Considering these were folks who had just fought the most horrific war in history, I can't imagine what those ladies were doing.

The next morning I rode down to Stromness with John Thornton, the captain of the MV Karin. The Karin is a big sturdy vessel, lots of deck space, wood hulled so its forgiving in rough seas, and with a feature that makes it a luxury yacht amongst dive boats: a diver lift! Nothing but nothing is better at the end of a dive than to kick over to the lift, stand up, and be raised the 6' up to the deck. With the midafternoon ferry from Scrabster the other divers came aboard, a mixture of Scotsmen and Englishmen, and we all went into a flurry of setting up and checking our gear. All told we were Ian Davis and Steve Harding on Evolutions, John Nicolson, Gordon Meek, and Barry Baloo on Classic Inspirations, Jason Flather on a Classic Kiss, Lorne Thomson diving independent doubles, and me on my Meg, with Allen Stanger crewing, cooking, and generally being a helpful fellow.

It's a fine old nautical tradition to get drunk as a lord the night before sailing, a tradition not neglected on the Karin. Fortunately I don't partake, or for sure I would have been run over the first time I tried to cross a street - I never realized how deeply ingrained driving on the right is for me. There were sessions going on at the local pubs, with folk musicians reeling away, and the night ended in a late night feast of Yorkshire oatcakes from Jason. Mighty tasty, in a uncooked bacon kind of way. John's nickname is Ding, so called because everything he cooks ends with the microwave sound, and his assistance was crucial for keeping trichinosis at bay.

Day 1

Our first dive was on the 28,600 ton battleship SMS Kronprinz Wilhelm, 575' long x 96 feet wide. That's incredibly beamy, considering if you look at the Iowa class battleships they were nearly the same at 108' wide, but 875' long. As with pretty much all battleships she lies turtled, pulled down by the weight of her 305mm (12") guns. Conditions were very comparable to New Jersey, 51 degree water, visibility in the 20' range (though it often is much better.) At 140' deep there was plenty of time to poke about and make my acquaintance with the wreck. Urchins were everywhere, as were sunstars, 13 legged cousins of the starfish, while silvery Pollack cruised the wreck, and conger eels peeked out of the debris. Most surprising were the wrasse, who in their brilliant neon plumage looked like lost vacationers from the Caribbean. Barry works as a commercial diver up here, so he spent his dive filling a bag with scallops. These had rippled shells, as opposed to the smooth shells I’m used to seeing. Also different is that up here they eat the orange guts, which he referred to as the roe. I had some in a restaurant the next day, not bad, but not my first choice. Like I tell my kids though, you don’t have to like it, but you do have to try it.

For our surface interval we pulled into Lyness. At one point it was the main fueling station for the British fleet, with a capacity of 100,000 tons of oil. It now hosts the Lyness Interpretation Centre. This museum, dedicated to the presence of the Royal Navy in Scapa Flow, is filled with the kind of artifacts divers hyperventilate over. Visitors are greeted by a 150mm gun from the SMS Bremen, which was actually recovered by a dive club! Also present is the propeller from the HMS Hampshire. This wreck is famous in the UK, as the so-called Iron Duke, War Minister Lord Kitchener was traveling aboard it to Russia when it hit a mine and sank (the U-102 that we had hoped to dive laid the mine.) Kitchener perished, along with 643 of 655 aboard. Inside the museum are various vehicles, torpedoes, small arms, portholes, diving helmets, anti-aircraft guns, uniforms, scale models, etc. Present too are the brass letters from the Royal Oak, which were stolen by a Canadian diver (the site is closed as a war grave), but returned 15 years later. One of the above ground oil tanks has been turned into a movie theater, and had a short film on the history of the area. Chances are good that Scapa Flow has come to you at some point, since the steel salvaged here, being pre-nuclear, is well-suited to medical instruments and other sensitive applications that are intolerant of radiation. In fact, as pointed out in the film, the Voyager spacecraft is built with steel from Scapa Flow. Globalization indeed. Out behind the museum is a sadly well-populated cemetery, with casualties from the Battle of Jutland, the HMS Hampshire, the HMS Royal Oak (victim of the U-47), HMS Vanguard (blown up in an accident), as well as numerous German airmen.

For the afternoon we headed to the SMS Dresden. This light cruiser, 5600 tons and 510 feet long, lies in 120’ on its port side. It is remarkably intact. After descending the line I headed to the stern, and did a series of limited penetrations. I knew they had lobster here, so I checked everywhere in NJ there would be a bug, but to no avail (I was later told they don’t really live in the Flow proper.) I came face-to-face with the same enormous conger eels we have at home, which seem to unnerve the divers over here much more. Perhaps they are more aggressive this side of the pond. A dogfish darted away from me, 6' long and with a beautiful camouflage pattern on its back. Plumose anemones adorned the wreck, but with much longer stalks than I’ve seen before. Finning down the wreck, I was able to dart in and out of holes in the decking, including a large one at the bow. The anchor chain disappeared off in the distance, so I followed it for several hundred feet to a large and impressive anchor.

That night several of us ate at the Royal Hotel in Stromness, which was lovely, followed by pints at Flatties Bar, which was horrible and mercifully brief. Within 5 minutes of arriving I was deafened by fat drunken Scottish girls braying along to Bon Jovi – is there any signal in nature that more clearly indicates Run For Your Life!

Some observations about UK diving, and being in the UK in general:

-Not since I was in Russia have I been so glad that I don't drink, because there is no way I'd want to compete with these guys! Best to not even pick up the gauntlet.

-Those of us from New Jersey cannot simply refer to it as Jersey, because they have the original and it’s confusing.

-Bailout/stage bottles are universally steel; I had about the only aluminum tank onboard, and that was a dry suit bottle.

-Generally speaking you kit yourself up entirely, including hooking your stages on. I usually need help with these, and felt like a needy pain in the ass.

-Bagging off at the end of a dive is much more common, though the preference is for you to come up the shot line (a term which is used interchangeably for either a shot that is thrown in, or a permanent mooring.) The boats do not tie in, leaving them free to pick up anyone who fails to come up the shot.

-Very popular are lift bags with their own .1 or .2 cubic foot bottles. They’re a bit heavy, but I picked one up anyways for the safety factor since they are simpler to operate, are less chance of an entanglement risk, and you are assured of a fully inflated bag.

- Dive boat captaining is a rough trade over here, as evinced by a photo of three skippers with their hands on the bar, faux fingernails painted onto their various stumps. Best of all was John Thornton talking about how whenever he is in the Karin’s engine room he pokes about a bit to see if he can find his long-lost digit! Remember that the next time you’re sitting around a campfire and need a scary story.

-On a completely different note, the milk doesn’t get refrigerated, leading to some clumpy horror scenes in the galley. I did appreciate how there was still a sense of bewilderment and shocked outrage (“Ach, the milk’s gone off!”) All I could think of was a friend of mine, who gets a facial tic if the milk sits on the table for more than two minutes. AMF, don't go near Scotland.

Day 2

The SMS Markgraf, in 140’, is the sister ship to the SMS Kronprinz Wilhelm we dived earlier, and also to the SMS König we dived later on. There were four ships in the König class, but the SMS Großer Kurfürst, which sank with rest, was raised and salvaged in 1933, a herculean feat of engineering. My drysuit, which had been seeping for much of the trip, now began to leak in earnest. The immediate effect was that I moved with a purpose, since I wanted to see as much as I could before getting cold. Apparently my moving with a purpose equals most other folks full sprint, since Meeko, Jason and John nearly lost their dsv’s when I jetted past them to the bow, and then zipped back again to the stern.

For the afternoon dive we visited the UB116. A coastal U-boat, it made a suicidal attempt to enter Scapa Flow two weeks before the war ended. Unbeknownst to it, the British had put in underwater hydrophones. After checking the schedule, and seeing that nothing was due, they detonated a minefield in the seabed and destroyed the intruder. It remained reasonably intact into the 1970’s, when it was decided that having a wreck full of torpedoes in an area frequented by oil tankers was perhaps not such a great idea. It was gingerly towed to a more appropriate area, and then, with clarity of purpose, the torpedoes onboard were used to eliminate the threat of the torpedoes onboard. What is left is quite an impressive pile of ur-uboat bits, but part of the conning tower is still recognizable lying on its side, as well as various bits and bobs.

John has a blessed device onboard the Karin, one which proved indispensable to my happiness: a tumble dryer. I thus had a sad little routine for the first couple of days: pull off gear, remove drysuit, squeeze out water, hang up drysuit, and by the time it's dry we're onto dive 2. Fortunately Scapa Scuba in Stromness has a service without parallel: show up in the afternoon with your leaky drysuit, and for 20 quid they patch it and drop it off at your boat in the morning. In an attack of hubris I had attempted to patch it myself the night before, but now saw the error of my ways and let the Honorable and Esteemed Ben work his craft. Winston Churchill once said you can always count on the Americans to do the right thing, once they’ve exhausted all the alternatives, and I guess in the same vein I eventually wise up.

Day 3

The MV James Barrie was the only non-warship we dived. In 1969 she ran aground in Pentland Firth, was refloated, and then sank for good while under tow (nearly taking her benefactor with her.) In what was becoming a ritual, I asked for beta while gearing up. Meeko gave me the very sound advice to avoid touching, upon pain of dissolving gear, the very oily ceilings. The ship lies intact on its side, and I was able to swim the length of it and make several nice penetrations into the holds. Sure enough the ceilings were studded with thick gloppy chunks of oil. Despite my best precautions I even managed to pick up a little bit, but fortunately only on a buckle, and it was easily wiped off.

Later we went to the turrets of the SMS Bayern, the namesake for a class of battleships. She was raised in 1934, but her four 600 ton, 380mm (15") turrets remain in 120'. They are a magnificent dive, with the shafts rising 35' proud, as they say there. Enormous ball bearings like bowling balls still sit in their chases. Near the base of one turret I found an opening, and dropped down below the sea bed. I was surprised to see there was an anchor in the opening, a little forward of the guns massive breech. Apparently all manner of junk falls down when you flip a 28,500 ton vessel upside down (the consensus was that it came from a steam pinnace, as a similar one has been seen on the Markgraf.)

That night gale force winds rocked the harbor. It was amazing to see white caps behind the jetties. Hats off to the pilot of the ferry boat, he slid that thing in pretty as can be (we had our cameras out just, uh, cause we wanted to record him doing such a good job.)

Day 4

I had missed the 150mm gun deck on the SMS Markgraf the first dive, so I was pleased to hear we would be returning to it. This time I paid more attention as I descended, and was rewarded with a leisurely tour past several of them. Dropping to the bottom I scouted about a bit, then squeezed into the wreck to poke about, with the massive deck for a ceiling. On the ascent I decided to swim to the other side of the keel, but lost my nerve - its such a broad featureless plain, you'd never believe it was a ship if you didn't know. My favorite part was the millions of brittle stars carpeting the hull, densely packed and waving their arms like in the flow.

The afternoon’s dive was the SMS Brummer, in 115'. This was an interesting ship, a high speed minelayer designed to get in, lay 360 mines, and then outrace any pursuit. It now lies on its starboard side in 110’, and while parts of it are trashed, quite a bit is still intact. I had to cut my dive short as I was low on oxygen, but not before taking a whirlwind tour of the bow and superstructure, with a few penetrations along the way. The bridge retains a cage about it, and what looks like a radar array but is actually from a searchlight.

Day 5

SMS Konig was a sister ship to the Markgraf and Kronprinz Wilhelm, and in fact they are all in a row on the bottom. On each of these dives I enjoyed swimming down them and grooving on their enormity. It was also possible to swim at various depths and see different things - the hull, the gun deck, the superstructure smashed off into the sand. I also did a few swim-throughs - is still a swim-through if your tanks clang away when squeezing in? After that I spent my time playing about in the superstructure. There was a brief Oh Shit moment when I wandered off looking for scallops, but I was able to relocate the shot.

Without too much conscious thought I played things very conservatively on this trip, with relatively limited penetrations and shorter run times than I would normally do (45 minutes-1 hour, versus 1½-2 hours at home.) Part of that was the leaky drysuit, part of that was some issues with the electronics on the rebreather. A big portion goes to me taking a dcs hit the month before, which had my wife pretty nervous about this trip, and truth to tell, me too. I don't consider myself a brash diver, but I'm often the one going deeper, staying longer, penetrating farther, and this time I had no urge to be that guy.

The SMS Brummer definitely merited another dive (or 10). I had thought I'd swum to the stern the first dive, but this time, when I penetrated and swam from the inside, I realized it just keeps going and going. It was like a really sharp, really dirty playground, where you twist up and down, over and around the pipes and sharp metal bits. Towards the end I felt a tweak in my left arm, which probably was nothing more than the gradual decomposition of my body as I age, but it still kind of freaked me out.

As the trip wound down, it was time for me to face the Demon. I love food, and I love all food - sea urchin gonads, beef tongue, sweetbreads, there's very little I don't like, and even less I won't try. You know where I'm going with this, don't you? Haggis, for the breezily innocent, is a sheep's stomach stuffed with the heart, lungs, and other organs, with a little oatmeal for texture. Mmmm, sounds appealing, doesn't it? They had it at the local Chippy aka the Fish and Chips shop, and it was my day of reckoning. At Meeko's suggestion I ordered a Haggis and a smoked sausage. "Would yeh laik yer sa'sage battered?" the countergirl asked. I'm not sure if it was an invitation for rough sex, or the culinary equivalent of dioxin, but either way the answer was an unqualified NO. In the final assessment, I have to say the haggis was pretty tasty. Not perhaps the sort of thing to have all the time, and I preferred the sausage, but I'd take it over gumbo any day.

Day 6

The last dive day was clear and warm. We had put off several times going to the HMS Pheasant, since it is a tricky dive under the best conditions, but today's looked ideal. Lying in 230', it requires careful planning, and perfect timing from the skipper due to a raging tidal flow through the area. The methodology for such dives is to drop the shot, and then attach a deco bar to it, aptly referred to as the Trapeze. This stays at 20', suspended by buoys, with a line that runs down to 180' or so. The last person up either unclips it, or cuts the line, and then all decompression is done drifting with the current.

All night I went back and forth as to whether or not I was going to make the dive. Several factors played on my mind: Would the latest patch to my drysuit leak? If I was wet it would be a miserable, possibly dangerous 90 minutes. Would the electronics on my rebreather fail, as they had done the previous dive? I don't mind flying it manually, except that now I had no backup. What was up with my arm the day before? Was that something, or was that nothing? Last of all, why did a voice in my head keep saying, Don't do this dive?

I didn't do the dive, but not for the sensible reasons above. As I was literally about to step off, the HUD on my rebreather went down, which meant not only was my primary suspect but my backup was gone. There's a difference between being concerned and being stupid, and diving a semi-functioning rebreather puts one squarely in the latter column. It was the first time I've ever called a dive, and the first time I've had gear fail me like that, but there's a first for everything and I was at peace with it.

I'll tell you what does prey on my mind. See, there are these two U-boats in the North Sea, and nobody has dived them yet... Hmmm, methinks I'll be back in Scapa sooner than later.
