In the wake of the dead: a sea kayaking pilgrimage to Oronsay and Colonsay via Jura.

For those who would like to follow the thread of this great trip to Oronsay and Colonsay via Jura from start to finish, I hope this index will be useful. We launched from Carsaig Bay NR735877. We paddled 136km over four days. On the outward trip we portaged the 2km over the Jura isthmus from Tarbert Bay in the east to Loch Tarbert in the west. We returned through the Corryvreckan.

Read Ian's trip summary here.

Postscript

If you would prefer not to paddle the Corryvreckan in the conditions in this photo, you can time your traverse for slack water:

The west going flood begins +0430 HW Oban (-0100 HW Dover)  at 7 to 8 knots at springs and +0515 HW Oban (-0015 HW Dover) at neaps.

The east going ebb begins -0145 HW Oban (+0515 HW Dover) up to 8 knots at springs and -0100 HW Oban (+0600 HW Dover) at neaps.

The time changes by 6.5 minutes each day between springs and neaps. The constant between HW Dover and HW Oban does vary, so most accurate times are calculated by using HW Oban times (though not if you have calculated HW Oban indirectly from HW Dover!!).

Slack water lasts up to 30 minutes at neaps. At springs there is no real slack, there is always water moving about somewhere in the Corry. These times are pretty good as long as there is high pressure. Low pressure and wind can alter timing considerably.

A traverse of the Gulf of Corryvreckan disturbed only by a shoal of fish.

As we set off from Glengarrisdale Bay towards the Gulf of Corryvreckan which lies between the isles of Jura and Scarba...

...the morning's cold front began to clear leaving...

...Glengarrisdale in full sunshine.

Colonsay and Oronsay were now distant bumps on the horizon behind us.

All attention was now on the western entrance of the Corryvreckan ahead. As we approached, we could still see breaking standing waves on either side of Eilean Mor but our timing was impeccable and...

 ...as we slid our bows into the jaws of the 'vreckan, it had fallen fast asleep.

In fact at one point the water was so slack we had to resort to paddling.  However, within 5 minutes of slack water we were travelling at...

...8km/hr with minimal paddling effort. Even Maurice began to relax due to the mill pond conditions as we crossed the mouth of Bagh Gleann nam Muc (Bay of the Glen of Pigs) and inside Eilean Beag. It is at this point that unstable standing waves appear at the end of the flood (especially if there is any swell from the west) and a race and anomalous waves develop during the ebb.

All of a sudden the water beside Maurice's boat began to boil and he nearly jumped out of his dry suit. He thought the tides were about to engulf him. However, it  was just a large shoal of fish driven to the surface by either the tide or a predator such as a seal or a cetacean.

 Leaving the Bay of Pigs our speed increased to...

...12km per hour as we approached Carraig Mhor and a quick glance astern...


...showed that Eilean Mor was already over 2km behind.

This telephoto shot through the Corryvreckan shows our last distant view of Colonsay on the horizon beyond Eilean Mor.

As we rounded Carraig Mhor, the narrowest part of the Corryvreckan, at 14km/hr David had his sail up and then proceeded to take his legs out for a stretch. Sam's only comment was "Legend!"

I have been through the Corryvreckan many times but this was easily the calmest. Just in case you think it is always like this, have a look at...

...this photo, taken when Tony and I were entering the Corryvreckan from the NW, it might just give you second thoughts..

As we passed Port nam Furm at the east end of the Corryvreckan, we entered the Sound of Jura and the last leg of our journey to Jura, Oronsay and Colonsay.
