Flat Earth Kayak Sails preview


David enjoys the Flat Earth Kayak sail on a Quest LV.


My friend David and I have been experimenting with kayak sails for nearly two years now. We are both keen sailors and windsurfers so it seems very natural to us to put a sailing rig on a kayak. Indeed when "sea canoeing" took off in the west coast of Scotland at the end of the 19th century, nearly all were fitted with sails. Note, those who fancy experimenting with a Mark I brolly, please wrap some pipe insulation round the handle. It is more comfortable to hold and when the inevitable happens and you let go, it won't sink!


Sailing rigs on sea kayaks are not that common in the UK but are very big in Australia and New Zealand. We got in touch with various people over the Internet and have tried a variety of different rigs including the Pacific Action V rig (above). This is quite heavy and not particularly aerodynamic, although it is great fun downwind in a strong wind, it is not much fun in lighter winds and you really can't reach across the wind with it. The sheeting system, which adjusts the angle of the two masts is not exactly intuitive, unless you are dead downwind. The sail is also really just a flat triangle, with little shape in it. However, in a force 5 with a good sized swell, we got the old Aleut Sea II double up to a burst speed of 22km/hr by a mixture of paddling, surfing and sailing!


Next we tried Mick MacRobb's Flat Earth medium sail from Australia. We have used these sails on long open crossings such as to Ailsa Craig, long lochs such as Loch Fyne, Loch Linnhe, Sound of Mull, Loch Sunart. We have used them in coastal chop in the Firth of Clyde to open Atlantic swell off the west coast of Islay and in winds up to force 5 and in strong tidal waters such as the Sound of Islay and the Solway.

What we can tell you is that Mick's design is absolutely stunning. It's a proper sail, made by an expert sailmaker, as any sailor/windsurfer will see by the way the roach is bending off nicely towards the head of the sail in the bottom photo. This twist gives the sail a very broad range of usable wind strength, which other sails, without a sailmaker's skill in shaping, simply can't match.

All the fittings such as the mast, the mast foot and the goose neck have all been custom designed for the purpose and are not simply bits adapted from yachts and dinghies. The battens are even sewn into the sail with just the right amount of tension, saving you more guesswork using a tensioning strap.

The deck fittings are easy to fit using a drill, bolts and washers. On some kayaks you might be very lucky and not need to drill too many holes, because you can use existing recessed deck fittings.

You don't need a rudder to steer with Mick's rig, you raise the skeg and it points up into the wind and you drop the skeg and it bears off downwind. You don't need outriggers either! We carry on paddling when using the sail but in a force 4 you can expect to make about 9km/hr on a broad reach without paddling. So far the maximum we got on a GPS burst speed was 23km/hr sailing and surfing downwind on a broad reach. With a sailing rig you don't wait for the right swell, you overtake them then take your pick! 14km/hr is an easily achievable speed in force 4 to 5 and 9km/hr at the bottom end of force 4 and, again without paddling 6-7 km/hr in a force 3.

When broad reaching or beam reaching, paddling has a synergistic effect, increasing the apparent wind, so sheet in and go! We did not experience a "death roll" with Mick's rig though we did with the Pacific Action V sail. If anything, the Flat Earth sail steadies the kayak in difficult conditions. The sail won't beat into the wind, so tacking only happens if you want to change direction, round a headland say. We found if you raised the skeg but kept sheeted in the kayak would gently nose into the wind, the sail would depower and a couple sweep strokes would get the wind filling in on the other side of the sail. Downwind, gybing was easy using stern rudder/sweep strokes to turn the nose of the kayak through the dead downwind position. Because there is no kicking strap, the boom rises during the gybe, depowering the sail so there is little risk of capsize and the gybe is a slow, gentle sequence. You can speed the boom on its way over with a deft flick of the paddle on the sheet and then the gybe will happen more quickly. However, you need to have sorted out in your mind before hand how and where you will put in a quick brace, if required.


The V sails are really downwind only but as you can see in the above photo, you can close reach with Mick's Flat Earth rig.

Kayak sailing is a really dynamic and exciting activity so watch this space, our little group will soon have 5 of Mick's sails. Once my knee is better and I can get round a bit easier, anyone who fancies a shot would be most welcome to come along on one of our trips. You will need to swap kayaks as some of the rig fittings need to be bolted to the kayak.

I really can't understand why there is so little interest in sea kayak sailing in this country. There is not a single mention in Gordon Brown's otherwise excellent book Sea Kayak. I am not a great one for sea kayaking badges but as far as I recall, there was not a single mention of sailing rigs in either the 4* or the 5* syllabus either.

Friends have suggested that this lack of interest in the UK is because previous rigs have basically turned your simple sea kayak into a complex, heavy sailing boat with outriggers etc. and then you end up sailing instead of paddling. That is clearly not the case with Mick's rig which is quick to rig, light, simple and an adjunct to paddling, just as catching a swell is.

Others have suggested it is because your kayak must need a rudder because a sailing dinghy needs one. That is clearly not the case, a skeg helps but we have used the sailing rig quite happily with the skeg kept up.

Another concern is capsize and entrapment and when I started using sailing rigs I did have my knife to hand! I am not worried about entrapment because in Mick's design, all the lines are well forward of the cockpit. There are two control lines, an uphaul to pull the mast forward and up (when it then becomes a fore stay) and a sheet. Both are connected to the mast or sail by shock cord so there is some give, in case of gusts. With the rig up, control lines are all out of the way of paddling/rolling paddle arcs so you are free to carry on paddling. The sail can be raised and lowered very quickly. When rolled up on deck, they are very unobtrusive and are unaffected by rescue practice.

You can roll with the sail deployed. I have not tried this yet myself, because of my knee injury but here is a rolling clip on Gnarly Dog's blog. It is actually quite easy to prevent a capsize because, at the speed you are going at in windy conditions, there is a huge amount of lift generated by simply trailing a paddle blade out to the side in a static low brace position.

Once my knee is a bit better I will get back to testing and hope to submit a full review and long term test to Ocean Paddler magazine which will also appear here after the magazine has been published. At the moment there are no UK dealers and you need to order direct from Mick but I hope that very soon a well known UK dealer will start to import and distribute these really excellent sails. I am afraid this preview can only give you a brief idea of these sails's abilities and because my knee operation got in the way, much of it is through the experience of others. What I can say is that I have literally been blown away by these sails and I can't wait till my knee gets better enough to give them a thorough long term workout!

I have posted detailed fitting instructions for Flat Earth Kayak Sails here.

Made in Scotland from girders and glaciers.


We now entered the outer part of Loch Etive. The loch stretches away for 30km into the mountains, where it becomes the most fjord like of the Scottish sea lochs. It was cut by a massive glacier that gouged a U shaped trench through the mountains and was flooded by the sea when the glacier melted.


At the Connel narrows the view is dominated by the Connel bridge. It was built in 1903 to take the railway from Oban to Ballachuilish and its slate quarries.


In 1914 a roadway was added, which allowed vehicles to cross when no trains were on the line. The railway was closed in 1966 and since then it has been used only for road traffic. A one way system controlled by traffic lights is required as the bridge is not wide enough for two lanes. When it was built in 1903, no one could have expected the explosion in road traffic, even in this relatively remote part of Scotland.

As we approached the bridge it looked as if a light plane was going to try and land on it, but it was on its final approach to the small airfield just north of the bridge.


The Connel narrows formed where the glacier met the warmer sea and melted. As a result the narrows are very shallow and if the sea level was only a few feet lower, Loch Etive would have been a fresh water loch like Loch Lomond, Loch Shiel and Loch Morar.


The bridge is of cantilever construction and like irn bru was made in Scotland from girders, not to be drunk but to last!


We drifted under the bridge just an hour before HW slack and there was hardly a ripple to disturb the surface. However, there is a shallow sill, just below the ducks, over which the spring ebb tide pours as the Falls of Lora. A series of standing waves creates a very testing playground for play boaters. Tony Hammock of Seafreedomkayak has produced an excellent guide to kayaking the Falls of Lora.

All quiet at Dunstaffnage


Leaving Ganavan Bay the conglomerate rocks of Ganavan Hill tumble steeply into the sea. Silver birch cling to the steep slopes and survive on ground that is too steep for sheep to get at their seedlings.


Rounding a headland a strip of low lying ground links Ganavan Hill to an isolated hill called Chapel Hill which was once probably an island. On the flat ground, the modern buildings of the Dunstaffnage Marine Laboratory of the Scottish Association for Marine Science are being extended with the construction of a new teaching building.


We had now reached the point in our voyage where we turned east through the gap between Rhuba Garbh to the north end of Chapel Hill and the island of Eilean Mor. In the distance the snow covered slopes of the Benderloch mountains rose into patches of drifting cumulus clouds.


Through the trees, at the back of a delightful gravel beach, we could just make out the grim curtain walls and towers of Dunstaffnage Castle . The name has mixed Gaelic and Norse origins, Dun means fort in Gaelic and staffnage is derived from "stafr nis", staff headland in Norse.

There has been a fortification for at least 1500 years. In the days of sea communication, this site, at the junction of Loch Etive, the Firth of Lorn, the Sound of Mull and Loch Linnhe, had incredible strategic importance and the castle walls would not have been hidden away in trees. They would have dominated the landscape from every direction. Dunstaffnage was the capital of the ancient kingdom of Dalriada, which was founded by the Scots, who came to this coastline from Ireland. They brought with them the Stone of Destiny, upon which their Kings sat to be crowned. The stone reputedly came from the Holy Land via Ireland and Iona to Dunstaffnage. It was moved inland to Scone Palace in 843 with the advent of Viking raiders.

Most of the current castle was built in the early 1200's by the McDougall clan, who paid homage to King Hakon IV of Norway. In 1249 Alexander the II of Scotland assembled a fleet in Oban in order to seize Dunstaffnage as part of a campaign to regain control of the Western Isles from the Vikings and their allies. He died unexpectedly on the island of Kerrera and the attack was aborted. Unfortunately for the MacDougall's the respite was short lived. Dunstaffnage was captured after a siege by King Robert the Bruce in 1309, after the MacDougalls had backed his rival John Balliol. In 1470 it was transferred from the Royal estate to the Cambell clan.


A little further round, we could see the more modern addition to the castle, the Gatehouse, which is still the occasional private residence of the Captain of Dunstaffnage. The rest of the castle is open to the public for a small charge to Historic Scotland who now care for it.


Nowadays Dunstaffnage is a quiet backwater and we drifted past the castle in peace, to enter Loch Etive.

Trouble in the Isles

The Scottish tourist board have been hoping for a record breaking tourist season. What with the recession, volcano dust interrupting plane flights and the exceptionally dry June here in Scotland, things were looking promising....


This is the MV Clansman, she is one of the hardest working ferries in the Calmac fleet. It is 0743am and she is steaming out through the Sound of Mull towards Coll, Tiree then back to Coll. After visiting the islands she will return to Oban for a mere 40 minutes before heading back through the Sound of Mull and out to Castlebay in Barra! She is known as the loudest vessel in the Calmac fleet. We were camping at the SE entrance to the Sound of Mull but woke up when she started her engines 18km away in Oban! Sadly she has suffered a catastrophic engine failure and the life line she provides to Coll, Tiree, Barra and South Uist has been disrupted.


To maintain service, Calmac have transferred the MV Hebridean Isles, which normally does the Kintyre, Islay, Colonsay, Oban run, to help cover the Clansman's normal routes.


The MV Isle of Mull, which normally does the Oban to Mull run has also been drafted in to help cover the Clansman. The effect of this is that services to Islay, Colonsay, Mull, Coll, Tiree, Barra and South Uist are all affected. To make matters worse, the Scottish school holidays have just started.

If this was not enough, the record dry June has left reservoirs depleted in what are some of the wettest parts of the world! We now have an almost unbelievable situation where Mull is having to import water at a time when the ferries have restricted sailings!

As we say in Scotland, "It never rains but it pours!"

A welcome break at Ganavan.


We followed the Argyll coast across the sweep of Ganavan Bay and landed at its NE end.


The other end of the beach has beautiful sands but was crowded with walkers from Oban enjoying the first sunny day of the year. We chose to land at the quiet end and did not mind the cobbles.


We were rather hot and parched because we were all in dry suits, with multiple thermals underneath.


So it was a great excuse to stop for second luncheon. Jim W's kayak is a Sea King. The low winter sun showed off her fine lines and chines.


Jim produced orange slices while Phil got the stove an for tea but as it was afternoon, it was appropriate for a variety of malt whiskies to be sampled. On this occasion we had Bruichladdich Rocks, an 18 year old Glenfiddich and a 10 year old Springbank. I am sure there was another one but for the life of me I cannot remember what it was!


We enjoyed the thin winter sun in this beautiful spot. Recently a new housing development has been built on the site of a former RAF sea plane base in the SW corner of the bay. In a way it is a pity that such a development has taken place in such a beautiful spot. However, access is certainly a lot easier now. The owners of the previous holiday village of chalets, which was there from about 2004 to 2009, used to charge to launch from the beach, in addition to parking.


At our end of the bay, all was natural and wild. The view extended across the blue waters of the Lynn of Lorn to low lying Lismore, then to the mountains of Morvern beyond.

The skies cleared over the Firth of Lorn.


We left Oban harbour under cloudy, grey skies...


...but no sooner had we entered the Firth of Lorn...


...than a remarkable meteorological transformation took place...


...and the clouds parted above us.


We continued our voyage up the Firth of Lorn under welcome winter sunlight.
