The Clyde, a river of change.

From the Kingston Bridge we continued down the River Clyde towards the Clyde Arc bridge. It was completed in 2006 by Halcrow. It is a tied bowstring arch of steel box section, which supports a precast reinforced concrete deck. From this view, the Glasgow Tower (beyond the bridge) looked like an arrow set for launch from the Arc's bow!

The Arc crosses the Clyde at an angle and is therefore, quite logically, better known by its alternative name: the "Squinty Bridge". It was built to service the growing media centre which has developed on the south bank of the Clyde.

The tower of the University of Glasgow can be seen from the now empty Finnieston Quay. At one time it would have been lined with rows of ships, several deep, which would also have extended into the now filled in Queen's dock.

The Finnieston crane now stands motionless above the river. It is the furthest upstream of several Titan cantilever cranes on the Clyde. It was used to load steam railway locomotives from the Springburn locomotive works onto ships. At the height of its industrial power, Glasgow manufactured 25% of the World's railway locomotives.

The tower was built by Cowans, Sheldon of Carlisle, on piles by Sir Willam Arrol of Glagow and the cantilever was by the Cleveland Bridge and Engineering Company.

Continuing down the north bank and Finnieston Quay, we approached the Clyde Auditorium, which you will be unsurprised to learn, is popularly known as the "Armadillo". It was designed by Foster and Partners and built on the site of the now filled in Queen's dock.

The Glasgow Harbour Tunnel was built in 1896 and connects Finnieston Quay on the north to Plantation Quay on the south.  Two rotundas provided a lift down to two vehicle and one passenger tunnels. This is the Plantation rotunda the Finnieston rotunda is just to the east of the crane. The vehicle tunnels were closed in the mid 20th century but the passenger tunnel remained open until 1980. The tunnel was never a financial success as it faced strong competition from the Finnieston Ferry, which had an unusual lifting vehicle deck so that it could load and off load at a vertical quay side, regardless of the height of the tide. It started service in 189o and operated until 1966.

Plantation Quay on the south bank has been renamed Pacific Quay and is now the centre of Glasgow's Digital Media Quarter. This is the Scottish Television building.

Pacific Quay is now linked to Finnieston by two footbridges. The first, Bell's Bridge, was built in 1988 to service the Glasgow Garden Festival which took place on the filled three arms of Princes Dock, which lay behind Pacific Quay. Bell's Bridge was engineered by Crough and Hogg and its two main spans are supported by cable stays from a rotating pointed tower, which opens the bridge and allows bigger ships to pass through. Until 2001 the paddle steamer Waverley regularly went through the bridge to her berth at the Broomielaw but she now berths below the bridge at Pacific Quay.

Once through Bell's Bridge, our view of Pacific Quay was dominated by the BBC Scotland building, the Glasgow Science Centre and the Glasgow Tower. At 127m high, it is Scotland's tallest building. It has a teardrop cross section and rotates 360 degrees, so that its slimmest outline faces into the wind.

The curious bulbous building behind the Science Centre is Glasgow's IMAX cinema. So far it has avoided being called the "Glasgow Blob".

We now passed under the most recent of the City centre bridges. It is the Millennium Bridge completed in 2002 and engineered by MG Bennet Associates. It is built of steel lattice supporting a sheet steel deck. Hydraulic rams lift the two centre spans to allow vessels to get further up the Clyde.

One thing is for sure, this river city has changed out of all recognition over the last 3 decades and it is changing still!

The Dun gap, St Kilda


As we neared the end of our circumnavigation of Hirta we entered the narrow Dun gap which separates Hirta from its near neighbour Dun. Many sea kayaking trips never have the opportunity to go through here due to the huge swells which normally drive relentlessly through the gap. We were indeed privileged.


Once we were under the cliffs of Dun we could see the stack of Giasgeir with the hill of Oiseval, 293m, which forms the far side of Village Bay. A male eider duck came flying through at high speed.


Eiders are Britain's largest ducks. And are sometimes called "Whoo Whoo" birds on account of their mating calls in late winter and early spring.


As we emerged from the gap we turned sharp left before Giasgeir.


Murty knew of a large cave that led to a tunnel that would take us out into Village Bay on the far side. Sea kayaking doesn't get much better than this.

The west coast of Hirta in the St. Kilda Archipelago


We emerged from the threatening darkness of the Hirta/Soay gap and made our way south down the west coast of Hirta.


Looking back to the north, Soay was still wreathed in its cap of cloud.


The cliffs on this side of Hirta were no less impressive than on its north side.


From the summit of Mullach Bi (358m) the great headland of Carn Mor plunges into the sea.As we approached we thought we could see light coming through what appeared to be a cave.


It turned out to be a long tunnel which made its way right through the headland from the west to the south coast of Hirta. It is called Geo Creag an Arpaid and we were lucky enough to be there when it was calm enough to paddle right through!

Sea Kayaking through the gates of Hell!


The Cuma reported a force 4 to 5 SW wind on the far side of the Hirta / Soay gap.


As we went down the west side of Stac Soay, the gap between it and Stac Biorach looked like the gates of Hell!


Fortunately we did not need to pass through to Hades as a tunnel appeared leading right through to the other side of Stac Soay.

Unfortunately there will now be a short intermission. The staff of seakayakphoto come are headed for the fair isle of Islay. We have heard tales of many shore side distilleries, with magical names like Bruichladdich, Bowmore, Laphroaig, Lagavulin, Ardbeg, Caol Ila and Bunnahabhain.

We may be gone for some time.......

Purty sea kayaks and the great tunnel of Geodha na h-Airdhe, St Kilda


Geodha na h-Airdhe is a 140m long tunnel right through the great headland of Gob na h-Airdhe on the north coast of Hirta in the St Kilda archipelago.

Alan comes through in his Nordkapp LV. I think this boat is one of the purtiest sea kayaks around!


Fiona F and Murty come through as the MV Cuma makes an appearance behind.


The scale of this arch is difficult to describe, in truth it is a tunnel!


Yup the Nordkapp LV sure is a purty boat. Pity the same can not be said of all those who paddle one! Photo Jennifer Wilcox.


With Boreray as a backdrop to the NE, Lena and Jennifer paddle across the great sweep of Glen Bay where we had arranged to rendezvous with the Cuma.

The Cuma's purpose will be revealed tomorrow...

Sea Kayaking St Kilda: Na Cleitean Stac


Leaving Bradastac, we passed under further huge cliffs below Glacan Mor. We saw another stack ahead, Na Cleitean stac, and in the distance the headland of Gob na h-Airde with a cloud capped Soay behind.

As we approached the headland of Gob na h-Airde we realized we would not be paddling round it, there was a tunnel right through it!


Several people have emailed about my source of the names of the geological features that are not on the OS 1:50,000 map. I have used the Mathieson map from 1928.
