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.

  1. Hi Douglas. Hoping to go round Jura in August; slightly apprehensive re the Corryvreckan😟 You entered the west end just on slack water but within a one or two kms the stream was at 12-14km/hr?? It’s a fantastic blog BTW. Regards Stuart

    1. Hi Stuart I wish you a great trip. There is really no period of slack water at springs and at neaps there is only half an hour or so. As we were paddling with the stream you need to subtract our paddling speed which was probably 5-6km/hr. However, the rule of thirds dose not really apply to the Corryvreckan and it will be running at full speed about an hour after slack. :)
