Pushing further and further forward, the wreck of the Coln began to envelope us.
The walls, floors and ceilings of her vast structure were all around. Ahead the soft green glow led to our exit.
The wrecks had captured our hearts and minds in the past week. Now the Coln was literally holding us in her embrace.
Junior and myself were on the swim through challenge. First stop the stern.
The entrance was just above the seabed at about 33m, sitting diagonally down from the stern gun and capstan.
We sat there for a moment peering into the gloom until eyes adjusted and we could see the light ahead indicating our exit.
Pushing in and immediately turning right, we were inside the ship. At first, it was hard to assimilate the tangled structure with the inner workings of a ship as everything was sitting at 90 degree angles to where it should be. But as you properly orientated the pipes and suryfaces in your minds eye, it started to take the correct shape. The Holy Grail of this swimthrough was a tiny hatch. It sat low down and below our horizontal bodies and was easy to miss.
Shining torches into the darkness we could make out the emergency manual steering wheel.
Emerging at the wreckage created by the salvors, the race was now on for the second part of the challenge, the bow swimthrough.
Coming up on top of the wreck, the port side hull, we zipped along to preserve as much bottom time as we could.
The entrance to the second swimthrough is tucked on the starboard side of the bow, close to the seabed.
Beyond the entrance, we ascended upwards for a short while before the journey took us inwards and upwards.
Here human activity was apparent with hatchways leading deeper inside At the curved conning tower, we peered inside one at a time in a bid to make out any recognizable features.
We were now on the top line of the ship. Holes in the hull above us or in the deck to our left offered us many ways out. We continued forward until the metal around us gave way to the open sea. Just behind us was a lifeboat davit pointing the way to the shotline and our slow ascent to the surface.
Coming later (when I get to a proper computer): the pics and our final dive before bidding a sad farewell.

Scuba Diving Scapa Flow Day 3
"Guns, I need guns."
Well the Konig-Class battleship SMS Kronprinz Wilhelm has enough to keep Neo happy in his fight in the Matrix.
And chief among them are the ten massive 12-inch cannons in the five gun turrets that bristled the deck of the heavily armoured dreadnought.
Despite the weaponry, she saw battle only once, in the Battle of Jutland when she kept up the devastating shelling of the British fleet. One can imagine the ear-splitting boom and the clouds of acrid smelling cordite as the gunners fought time and fatigue to keep up the barrage of deathly shelling.
Thankfully, some of those impressive armaments are still visible, even though the ship turned turtle as she sank to the bottom in about 37m of water when the crew scuttled her in a final act of defiance against the Allied forces.
The shotline takes you down to the the bottom of the hull, on the port side, a third of the way from the upturned stern - or pert little arse, as Emily would describe it, at about 22m. From there, we crested the armour plated hull and followed her down to the seabed, the wreck casting a gloomy shadow over our watery path into the darkness.
At about 30m, as our eyes became adjusted to the low light, we were presented with what looked like an overhang. But as the bright beams of our torch danced across the ceiling - or what should have been the gundeck when she plied the seas - our eyes caught sight of the first guns, two 5.9in weapons, one pointing sternwards.
But the best was yet to come - two of the 12-in gun turrets. As massive as the turrets looked underwater, it must have been cramped, deafening and dirty for the gunners keeping up with the action. Lying almost on top of each other, their massive barrels protruded outwards, their stepped armour giving an appearance that they were telescopic.
The second of the two disappeared into the gloom, but shining our torches ahead of us we pressed forward into the every narrowing passageway to follow the barrel along the ceiling.
After retracing out steps, we were back outside the wreck and heading towards her 'pert-little arse' at about 35m-ish. For such a huge battleship, it was tiny.
Ascending over the upturned hull, we moved forward past the two giant rudders. I was anticipating this would be the least interesting part of the dive - I don't want to dive on an upturned bathtub, I may have been heard to say as we planned the trip - but it actually provided a wealth of interest.
At one point we could see three different thicknesses of armour plating, from the 12in at and below the water line to the thinner cover on the upper decks. We also came across parallel rows of metal sitting across the wreck, these were the fixing supports for the heavy armour and are not seen anywhere else.
As we neared 50-odd minutes were made our way slowly to the surface.
Dive two was on the Dresden, another of the lightcruisers and the only one sitting on her port side. She lists over more than others so it took a bit of time to get orientated as we dived the forward section, as he deck is slowly peeling away from her body, like a partly opened can of tuna, to expose her innards.
Who said Junior's an anchor?Number One, Number Two, Junior and myself decided to take a slight detour and we followed her anchor from the deck hawse and she stretched across the sandy seabed for a hundred or so yards.
That seen we headed back to the magnificent bow, festooned with a carpet of marine growth, including the beautifully bright plumrose anemones and white deadman's fingers. For those interested in their feeding habits, spending a few minutes simply watching them pulsate in the gentle current is an eye-opener.
With our no-decompression limits approaching, we headed towards the shallower part of the deck before making an ascent to the surface, Number One showing us the right way.
Jono and Ash, meanwhile, had headed back along to wreck to take in her conning tower and bridge. The control tower itself is resting on the seabed, blocking the tiny hatch inside. Peering through the letterbox sized viewing slits in the armour plating, the brassing dials and fittings are still visible.
The pair also saw the 5.9in gun resting close to the bottom and the giant lifeboat davits that curved round to rest on the seabed below. With their computers indicating they were approaching no-deco limits, they returned and made their way safely to the surface.
Viz was about 8m, temperature about 12degrees and only slight current on both wrecks.

Scuba diving Scapa Flow day 2
The fierce hiss of the cold water of Scapa Flow roaring into the ballast tanks of the Coln lightcruiser would have been deafening.
In a final act of defiance, the German crew were putting into action 'Paragraph 11'. Each member of the skeleton crew were doing their bit to scuttle the ship.
It had been a miserable and cold seven months interned in the Orkney Isles as the politicians dithered over the spoils of war following the declaration of peace in November 1918.
But as the sailors raced around the ship opening the valves that would fill the ship with water and take her to the sea bed some 35m below, the spirits would have been warmed.
Thanfkfully, their defence of the Motherland and two-fingered salute to the political windbags has left us one of the world's best shipwrecks.
The full scale of the oln slowly emerged from the green-tinged water as we descended the shotline to her port side at about 17m. The line from the surface is tied off close to one of the lifeboat davits about two thirds from the bow.
Following their arch-like shape, we headed deeper along her deck, sitting at a 90-degree angle from the sandy bottom.
With the wreck on our right shoulder, the six of us headed forward towards the bridge. Now just a skeleton framework, the bridge's soft steel outer has rotted away and, where she should be linked to the conning tower is now a twist of metal.
Initially, I missed the importance of the lump of metal sitting isolated from the bridge, until I recognised the range finder sitting on top of the armour-clad control tower with the ring of narrow letterbox-sized viewing slits. From here the crew were have operated her 5.9in guns that have long since disappeared from the wreck.
Continuing foward we passed the anchor chain capstans, the holes for the crew to manually turn the winch in the event of mechanical failure still visible.
Drifting off the wreck at the bow and looking back, the wreck looked immense, the deck disappearing ghostlike into the distance in one direction and the straight lines of her bow in the other. Her body was covered in a layer of marine growth with colourful plumrose anenomes and bright deadman's fingers scattered across he skin.
Most of the dive had been spent in that 30m region so we headed shallower and headed back along her portside, poking into the surface damaged by deterioration and salvage. Part way along, we can across the fixing for the armoury that looked like a three tiered wedding cake with a nipple on top (words of Emily, our skipper, not mine).
Sadly, we were soon at the limits of our EANx30 and had to ascent back to the surface. A massive shoal of fish, (fishy-shit, according to wreck-loving Emily) schooled around the davits as it to give us a sent-off.
We had only scratched the surface of the immense cruiser.
After lunch and another chat with Emily (her briefing are as in-depth as you could hope, and such are the directions, you can't fail to spot all the features) we headed to the second dive of the day, The Karlsruhe.
Sitting in about 26m, the years and the salvors have not been kind to her. Parts of the deck at her bow have slipped towards the seabed, leaving much of her innards exposed. It means that the anchor capstans can be seen through the wreckage to a platform and hydraulics that should sit two decks down.
The great thing about the Karlsruhe is that her guns are still there. One sits about seven metres below the shotline, lying on the seabed. Her barrel was impressive, but the loading breach of the gun, that is usually hidden away within the turret, looked huge.
We headed towards the stern past a lot of twisted metal at the damaged midships trashed by salvors. Jono and Ash found a smim through and disappeared inside her body while Andy, myself, Number One and Number Two, headed through the wreckage, past another gun (this one with her barrel inbeded in the sand) and onto her hull.
While the bottom of the ship might not sound that fascinating, it provided some of her best features. The hudge rudder lay on the sandy bottom just behind the giant A-frames that jutted from her bottom. Support for the giant propellors that powered her through the oceans, the frame was covered in vibrant coloured marine growth - or hairy, as Emily called it - they were instantly recognisable as a unique feature to the cruiser.
At the rear of the ship her teak decking is still intact, although for how much longer remains to be seen. There was a small capstan on the rear that looked stunning. However, it is feared that the ravages of time and the sea will take her to the seabed as well.
Fifty-five minutes later it was time to head back to the surface and a well-earned pint mug of tea. Yep a pint mug. During the post-dive chat, Rich, sorry Number One reminded us that the wreck was no deeper than Dosthill. The quarry will never be same again!
We would all agree that today presented us with two of the best dives we have done and we could spend days on them both, getting to know their intimate secrets that have been hidden beneath the waves for 90-odd years.
Visibility was about 10m, and water was about 13 degrees. Current was non-existent on the Koln and only slight on the Karslruhe as it pushed us towards the stern. While the wind was Force 4s and 5s, because they were north-westerlies, the surface was choppy but happily devoid of too much swell.
Tomorrow: The first of the giant battleships.
