The smell of the sea hung in the air of Garbh Eileach.

We paddled across the channel which separates Dun Chonnuill  from Garbh Eilleach which is the biggest and roughest of the Garvellachs group of islands. Its name means Rough Island and though its NE tip is pleasantly wooded it...

 ...generally lives up to its name, as we discovered when we started to paddle down the steep cliffs which...

 ... line its exposed NW shore. The island is nearly...

  ...split in two at one point, at a gap called Bealach an Tarabairt, though I can't imagine anyone wanting to portage the rough ground. (A place name of "Tarbert" or similar usually means a portage.)

 Towards the SW end of Garbh Eileach the lazy swell was surging up the dark rocks...

...and exploding in cascades of spray, which drifted in the still air and cooled us. The smell of the sea hung in the air and our nostrils.

Crossing to the Garvellachs, the Isles of the Sea.

A big spring tide was ebbing down the Firth of Lorn. Soon we were making good speed at 9-10km/hr towards our halfway point the lonely rocks...

... of Dubh-feith. From the rocks we had a wonderful view...

.... to the south over the Slate Islands of Lunga and Eilean Dubh Mohr to the bulk of Scarba beyond.

However, our main attention  was drawn to the Garvellachs, which we were rapidly approaching. Despite the SW direction of the ebb tide, there is a NE going eddy, which curls round the NE end of Dun Chonuill (the first of the Garvellachs). It then joins the main SW flow, which goes down the SE of the islands. In a wind this eddyline can be an excitingly rough area. Even in no wind there was enough disturbance on the eddyline to get our faces wet. Our progress slowed to 2 km/hr until we entered the calm beyond. We had arrived at the Garvellachs, the Isles of the Sea..

From the Slate Islands to the Isles of the Sea.

It was midsummer several years ago, when Jennifer, Phil and I met below the whitewashed cottages that fringe at the little harbour at Ellenabeich on the Isle of Seil.

The harbour  was built to service the slate industry, which once flourished in these islands. They were known as the Slate Islands or the "Islands that roofed the World".

We were sweating in the hot sun by the time we launched below the cliffs of Dun Mor that back the harbour. So it was with great feelings of lightness and anticipation...

...that we glided over the cool sea to the skerries of Easdale.

Beyond the swell breaking on the reefs of the Slate Islands lay our destination, the Garvellachs...the Isles of the Sea.

I need to get out sea kayaking again.

Several people have recently emailed asking if I have given up sea kayaking. I am pleased to report that my absence from the maritime environment is temporary albeit somewhat prolonged. I faced the double whammy of a shoulder operation followed by a knee operation in the second half of 2013.

No sooner had I partially recovered from my shoulder operation in the summer, than  I upgraded my sling for a crutch in November. This little knee operation has also kept me off the water. In case the outside does not look serious enough to cause cabin fever, I attach the X ray...

The two large screws are pretty obvious. The shattered bone round the screwheads might be noticed by some as might the 6mm tunnel through the patella (kneecap). The other tunnel drilled through the femur (big bone at the top) is not so easily seen. The six biocomposite screws don't show on X ray, neither do the harvested tendons from a sacrificed muscle or the diverted tendon from the medial hamstring show.

Basically the ligaments that hold the medial side of my knee and knee cap have been reconstructed by a miracle of modern surgery. My left knee had been heading the same way as my right, which ended in a horrific dislocation while seakayaking to the remote island of Gunna in 2009. I now hope to have two stable knees, which will allow a return to sea kayaking and possibly other activities.

Anyway, I really need to get out sea kayaking again....

Dell Precision M6500 workstation overheating and running slow.

This is a sea kayaking blog but blog authors and visitors need to use some sort of  computer to access the Internet.  Please excuse a technology post!

For the last 38 months I have been using a Dell Precision M6500 workstation notebook. It works like greased lightening when editing and previewing large RAW files from my Canon 5D mk3 camera in Adobe Lightroom 5. I bought it because of great experience of three  Dell Precision M6400 computers I used at work, The M6500 was three years old in November 2013 and I wondered about extending its warranty. A quote from Dell offered 3 year on site pro support for £311. I thought about it too long and by the time I had made my mind up it was too late, as the offer period expired when the computer passed 3 years old. The reason I had not made my mind up is that in general  I do not buy extended warranties but this one did seem quite reasonable. Anyway, the computer had been trouble free for three years so...I suppose I thought I didn't need the warranty.

Exactly one week after the original 3 year warranty expired, the computer began to develop increasing problems, which rapidly worsened until it was almost unusable five weeks later. It began to slow down to a crawl, especially trying to do anything with big RAW files in Lightroom. The Windows experience Aero graphics score fell from 6.8 when the computer was new down to 2.8. The video drivers on the Dell site for the NVIDEA Quadro FX 2800M graphics card were rather old so I downloaded the latest (Nov 2013) drivers off the NVIDEA site.  I also updated to the latest Dell bios. Neither made any difference. The fans began to run all the time. The computer frequently and spontaneously rebooted. It suffered several blue screen of death episodes. On other occasions the screen would freeze and the mouse pointer locked up. I thought I might have a virus (as the symptoms seemed to have developed quite quickly). Scans with Sophos and Malware bytes revealed nothing and the problem persisted  even when the computer disconnected from the Internet. Suspecting overheating I installed ThrottleStop found the CPU and GPU were running at 95C. I decided to explore the computer's cooling system and used the online Dell service manual and dismantled the computer, which took about half a day.

This was how I found the CPU heatsink. The fine copper grille was completely blocked with dust. I suspect it built up slowly over the three years but as it built up, it gathered more dust increasingly quickly, which explained the relatively rapid and recent onset of symptoms.

This is how it should look. 

The CPU heat sink and grill fits in behind two other heatsinks and grilles which cool the graphics card and share the left hand fan. The graphics card also has another built in heatsink and fan on the right side. Its grille was similarly blocked but was even more difficult to get at and clean than the CPU heatsink and grille.

Once back together, the computer is running cool again at 50 to 55C, with hardly any noise from the fans. It is also working like greased lightning and the graphics score is back to 6.8.

It is a real pity that the whole computer (literally right down to the motherboard) needs to be dismantled to get at these heat sinks. It is not a great design. It is almost inevitable that other Precision M6500s will become affected. It took me about 7 hours plus a trip to Maplin for some Antec Formula 7 heat sink thermal compound paste to get it running again. It is not what I expected from a top end laptop. Perhaps they are built with a three year life expectancy for business but I am a private buyer and expected it to last longer.

Still I have avoided buying an expensive replacement so now I can afford to buy something else!

Sea kayaking desktop wallpaper calendar 2014.

I wish a very Happy New Year and a great 2014 paddling season to all visitors to seakayakphoto.com. As way of a celebration of the last year and in anticipation of sea kayaking adventures yet to come, here is the 10th annual sea kayaking desktop wallpaper calendar from seakayakphoto.com. I apologise for its late arrival. Neither my computer nor myself have been in the best of health.

As in past calendars, all the photos were taken during the previous year (2013). Unfortunately I have not been paddling over the last 6 months so the choice of photos has been more limited than previous years. Nevertheless I have been able to choose photos from north and south of Ardnamurchan Point, the Inner Hebrides, the North Channel, the Firth of Clyde and the Solway Firth.

January.

The Little Cumbrae lighthouse in the Firth of Clyde proved surprisingly popular despite being in the depths of winter. We met friends from the Drumchapel and Clydebank Kayak Club there.

February.

Rubha Carrach is on the exposed northern coast of Ardnamurchan. This coast is not paddled as often as it should be. Most circumnavigators of the British mainland cross to Eigg or Rubh' Arisaig on their headlong dash north. Paddlers staying in the area are faced with a circumnavigation of the whole Ardnamurchan peninsula if they only have one car, or a very long shuttle (over very slow single track) if they have two cars.

March.

Glenuig Bay opens into the Sound of Arisaig and views extend along the Ardnamurchan peninsula and to Muck and the other Small Isles. One of the great joys of winter paddling is returning in the dark!

April.

The north coast of Rum in the Sea of the Hebrides is a wild place. This is the sad wreck of the Jack Abry II, a French trawler that ran on to the rocks here just before midnight on the 31st January 2011. Fortunately, despite a gale and the surrounding cliffs and mountains, all 14 men on board were airlifted to safety by the Stornoway coastguard helicopter.

May.

The Mull of Kintyre is a rather committing paddle. The tide was moving at  6 knots and even in benign conditions there was no landing for 25km. It sticks out into the North Channel which separates Scotland from Ireland. On this misty day there was no sign of Ireland and we felt like we were paddling round the edge of the World.

Kylie the dolphin can often be found near Ardlamont buoy at the

mouth of the the Kyles of Bute.

July.

Murray's Isles lie in the mouth of Fleet Bay on the Solway Firth. In early summer they host noisy colonies of cormorants and gulls. The cormorants need to keep a watchful eye on their eggs and chicks as the gulls swoop down on any unguarded nest. It is a wonderful experience to drift in the tide past the colonies in kakak and watch, hear and smell the constant activity.

August.

Nothing can be finer than paddling across the mouth of Loch Fyne on a summer evening.

September.

The surf beach at Machrihanish is exposed to the North Atlantic swell and extends for over 6 kilometers. It is probably wise not to surf a fully laden sea kayak in amongst the surfers. The dune system behind the beach is one of the largest in Scotland.

October.

Shoe Bay is easily missed as it is hidden in the skerries at the mouth of Loch Moidart. The name comes from the very soft sand which swallows footwear!

The dramatic outline of An Sgurr is the highest point of Eigg in the Sea of the Hebrides.

December.

This is the view to the Small Isles from the silver sands of Morar Bay.  The bay is shallow and tidal and in a westerly wind, steep breaking waves build up as the ebb tide rushes over sandbars. On this trip the wind was from the east and all was calm.

Beady eyes and incontinent cormorants on the Murray's Isles.

 I was bound for the Murray's Isles which house a cormorant colony on their rocky crest.

From their lofty perch the cormorants can watch for...

...passing shoals of fish.

 Then a leisurely flap of ...

 ..their wings and they are off on a fishing trip...

 ...to feed their hungry chicks.  However, one adult always remains at the nest to protect the chicks as hungry herring gulls also nest in close proximity to the cormorants and are quick to swoop down on an undefended egg or chick. The cormorants' prime nest sites sit atop rocky pillars and by late summer...

 ...the rocks are caked in their white guano. Photographs can neither capture the sounds or the smell of a sea bird colony. The cormorants are bigger than the...

 ...the gulls but the gulls are patient, waiting for any opportunity to raid...

...a cormorant's nest.

 The gulls are also breeding  and...

 ...their chicks hop about the rocks in large groups before...

 ...they are fledged and take their...

 ...first flight down to the sea where they bob about in perfect camouflage.

This adult was keeping her beady eye on her chick and saw me off the premises.
