A winter storm sweeps the cliffs of Dancing Ledge

You wait weeks for a calm, sunny day to come along – and then one does. So in my back pocket I had a modest sea excursion planned for the TXL: the cliffs and caves west of Dancing Ledge.
It’s a mile’s walk from Langton Matravers village across the fields to the coast where the downs drop steeply to the former Portland stone quarry. From Swanage, about four miles to the east, Dancing Ledge is the first of the few sea access points along this cliff-bound Jurassic Coast.

Approach to Dancing Ledge

At low tide the lower, natural ledge is revealed, making getting in and out relatively easy. But to reach it you still have to scramble down a small cliff (below). It was easier to chuck the packraft backpack down before descending after it. Alone, rolled up or inflated, getting this far with an IK would be a struggle. This is why we like packrafts – and sea-going packrafts, so much the better.

The point where you scramble down overlooks the Bathing Pool (below). It was blasted out of the rock in the late 1800s by the strict headmaster of the local Durnford school in Langton. Pupils then trotted off to the pool each morning for the character-building ritual of ‘strip and swim’, but with a now reduced risk of being swept out to sea.
Decades later, James Bond author Ian Fleming attended the Durnford prep school and endured various torments before moving on to the more benign, towel-flicking environs of Eton. Unsurprisingly his Dorset years left a deep impression and later he named his 007 hero after a prominent Purbeck family, the Bonds of nearby Creech Grange. By 1999, when Bond 007 filmmakers had run out of Fleming’s dozen book titles, they chose ‘Non Sufficit Orbis’ or The World Is Not Enough, starring Pierce Brosnan. It was claimed as 007’s family coat of arms in On Her Majesty’s Secret Service, published in 1963, but was also the real Purbeck Bonds’ 16th-century motto. There’ll be a short exam later.

Back by the sea, even with wind speeds forecast at a lowly ‘4mph’ there was no balmy flat calm today, but that’s just the way it probably is with the wide open Atlantic to the west. Portland Bill or even nearby St Adhelm’s Head don’t do much to reduce the oceanic fetch driven by weeks of wind and squalls.

While setting the boat up I find today’s #ForgottenItem was the floor pad (left), which I was wanting to try again, despite being not entirely convinced. Two up, as we did near Skye last year, meant reduced legroom with the mat, but solo with my centrally positioned weight, I still like to think it will limit hull droop and floor sag to improve paddling response. (It does).

Alone, these exposed sea cliff paddles make me quite nervous, and a regular-sized packraft like my old Alpackas or Rebel would feel even more unnerving. The TXL’s healthy 2.8-metre length reduces that impression with less pitching, but I never fully relaxed today, so was happy it was only a mile to Seacombe inlet at which point I could get out and walk back if I wanted.
Away from Dancing Ledge things calmed down a bit or I just get used to them, but elsewhere I needed to keep an eye seaward as bigger waves rose up.

With my old MRS Nomad S1, I learned that with longer, high-volume packrafts like a TXL, no matter how hard you pump them up with warm, ambient air, after 10 minutes out on cooler water, a crease develops midway along the side tubes as the air in the hull cools and contracts and the boat effectively loses a few fractions of psi. Though beginners might worry they have a slow leak, this is normal with inflatables.
Ashore, I made use of Bond’s Pool of Torment (said to be the next film title) to pre-cool the TXL but knew it wouldn’t really work. Flooding the inflated boat for a few minutes is probably the answer. A little hand pump can only pack in, say, 2 psi at 18°C. Any more air forced in may burst the pump or stress the boat’s seams if done too often. But once part submerged by my weight on 12°C sea water, the hull cools and drops to, say, 1.8psi. It won’t get any lower, but it’s enough to lose its edge and means the boat paddles less efficiently. We can’t be having that!

In my heightened state of anxiety at paddling a new, exposed locale, I was pleased to see a lobster boat passing my way (above). Later on I catch up and and meet the Chatty Fisherman. For a while I was worried the tide might turn before I got to drag myself away, but, Purbeck born and bred, he was a local quarryman who used his summer hols to snag a few lobsters and had lots to say about everything, including reduced catches of late.
We used to get hundreds [of lobsters] here before the seas got warmer. Now I barely get a handful.”

There was no place to hop off and top up the boat, though I could always flip round in the seat and do it on the water. That said, I wonder if longer packrafts like TXLs could benefit from repositioning the inflation valve closer to the central seat, like my old Incept K40 solo IK. The MRS Nomad had the valve on the bow, which was handy. I suppose this might make expelling the air on rolling up more difficult, but we now have mini pumps with suction settings, making valve position less important. With a passenger or another paddler alongside, on-water topping up is less of an issue, but had I thought it through before adding the second skeg patch, I could have glued it at the other end, as the TXL is symmetrical, but then is the bow bag tabs would be at the back. So halfway down one side would be better, Anfibio. Sorry, I did I say something?

I paddle onward. Most of the caves have too much intermittent swell rolling in to get close, but one twin-mouthed cavern (above) looks like it could be safely threaded in the nippy TXL without me getting lifted by a sneaky swell and knocking myself out on the cave’s roof.

Inside the cave

Further west I see a few people wandering about on the foreshore ledges, announcing the inlet at Seacombe, another old quarry. As I get near, I line myself up to get lifted by a wave and dropped onto a ledge. It ought to be easy but ends up a bit of a bundle. Before I can climb out I get sucked backwards into another wave, which drops onto the boat. But though it looks ungainly, timing isn’t that crucial in a stable packraft that’s easy to hop out of quickly. Lord knows how a sea kayak would manage. Up on the ledge I drain the TXL before flipping it back over and giving it a few jabs of the handpump so it’s pinging firm again.

Seacombe cliffs

Putting back in, I’m alarmed to see my skeg lying on the rocks. My to-and-fro landing must have dislodged it. (It happened again on my next TXL; this is a fix). It is for moments like these (or, more commonly, distractions while packing up) that I wrapped it in hi-viz yellow and black tape. Had I lost it, the downwind paddle back would have been a bit squirrely, giving me something new to worry about until I realised the cause. Passing the twin-mouth cave I threaded earlier, the tide is already too high to repeat the stunt.

By the time I returned, Dancing Ledge was packed with day-trippers including groups of coasteering wetsuit-clad kids. They inched along the ledges, swam across cave mouths, and then clambered up to a narrow ledge to jump in. The next group was already lined up to follow so it all looked a bit sketchy and congested with just two guides for over a dozen kids (turns out it can be), but I bet they all loved it.

‘Beyonsaaaay! (or whatever kids shout these days).

As had happened so many times, a spell on the water without incident calmed the nerves. So I continue past the Dancing take-out and cast a wistful glance eastwards. It was only 2.5 miles, or an hour or so with the tide and wind and cliffs to the Isle of Purbeck’s southeast corner at Durlston Head, before a more sheltered turn northward to Swanage, another mile away over the Pevrill Ledge, the final hurdle into town. One for the next ‘calm’ day perhaps.

Anfibio Plus(+) fabric
Checking out Anfibio’s TXL page later, I see they’re offering the option of the TXL and similar long/double models in chunkier Plus (+’) fabric. It’s only 17% heavier but 80% more tear-resistant, depending on how you measure that, but costs only €70 extra. It looks like it might be similar to floor fabric or comparable with Alpacka’s much more expensive Vectran option.

Anfibio don’t fully explain why they’re now offering thicker Plus(+) fabric; has the standard proved a bit less durable? I admit Anfibio do focus a bit too much on the ultra lightweight side of things which, alone in a single-skinned inflatable, is not where my priorities float.
From my experience with stiffer PVC IKs versus more flexible rubber kayaks, I do wonder if a Plus(+) TXL or similar might be more rigid on the water without the need to pack it full of air. It may even exclude the need for the 900-g floor pad (it doesn’t). Along with what I estimate to be a <500g weight penalty, I imagine a Plus(+) TXL will roll up less compactly, but other than that it’s something worth looking into.

Quick-deflate seat
While I was never a fan of the mushy, twist-lok stem valves on the early Alpackas, I’m not a huge fan of the sprung, one-way inflation valves Anfibio use on their seats and backrests. Great for easy inflation and holding high pressures, but a pain to deflate when packing up; you have to jam a fingernail in the valve and scrunch the seat while it ever so slowly deflates. At least with an old twist-loks you could suck the air out. And anyway, you don’t need full pressure in a seat. Far from it.
There was talk of Anfibio modifying the seat valves for easy deflation but it’s not happened yet. Now the TXL is my sole packboat, I’m minded to set it up well. I failed to find anything other than Boston valves online. They’d work of course and will dump air really fast, but are a bit OTT and would need gluing in properly.

I had a spare dry bag with a neat twist lock valve a bit like Thermarest sleeping pad valves. But marrying it to the chopped off sprung one-way valve in the seat was tricky to do neatly. So I managed to do it not neatly (above left) with a bit of clear tube and lashings of Aquasure. Unfortunately the tube is narrow which slows things down or increases effort; win-lose. For the moment it works; I can unscrew the valve and roll up the huge seat, purging the air as I go. Looking back on this dramatic episode, next time I’ll just cut a hole and glue in a Boston valve (left) which are easily found online for under a tenner.

Eastwards from near Tyneham Cap: Kimmeridge Bay and the Ledges beyond on a very windy day

We took a lovely evening walk along the Purbeck coast east of Kimmeridge Bay, where for millennia the bands of bituminous shale have been burned or squeezed for their oil, like Kalamata olives. Good page here on Kimmeridge and its geology over the eons.

Just west of Kimmeridge Bay there’s even a lone oil well (right), nodding away incongruously since 1959 in the pastoral Purbeck idyll that inspired Enid Blyton’s Famous Five adventures which I devoured like Opal Mints in the Sixties. Blyton holiday’d for two decades in Swanage and elements of some distinctive Dorset icons, like Corfe Castle, find themselves transposed onto her book covers (left). There’s even an Enid Blyton Trail, which lists Kimmeridge.

East of the bay are the notorious Kimmeridge Ledges, submarine clay or dolomite beds which reach out to sea a few hundred metres. With the right sort of swell or wind (top of the page and below) they can catch out unwary paddlers when waves suddenly rise up and break far from the shore.

Windy day looking east across Kimmeridge Bay to the jetty below the Clavell Tower

Our evening walk coincided with low tide and calm conditions exposing parts of the ledges. They’re said to be rich in fossils and over the decades a local man, Steve Etches has collected enough to fill a museum in Kimmeridge village.
We walked as far as the outlook over Egmont Point where the path turns inland on its way over Houns Tout to Chapman’s Pool, just before St Alban’s Head (below).

Chapman’s Pool, just before St Alban’s Head
Kimmeridge Bay

To reach Kimmeridge Bay you continue past the village onto a private toll road to a huge car park with a daytime cafe. On both visits no one was at the toll booth which saved a few quid.
The east end of the bay has a handy slipway by the Wild Seas Centre. What a luxury it is to drive down to the sea’s edge and pop the kayak straight into the water to let it cool down and soften up while I parked the car. The high tide was just on the turn, but out here away from the headlands, the effect of any tidal current is minimal compared to the wind.

Jetty put in

I’ve got into the habit of opening the two side PRVs plus airing down the floor a bit at the end of a paddle for the drive home. Providing it’s not baking hot, I paddle with the PRVs closed which keeps the boat as rigid as a stick. Today I realised you can’t top up with a push-pull barrel pump stood in the boat on the water; you need to drag it all back ashore to stand on the ‘stirrups’. It takes just a few strokes to fully inflate the Igla back to 0.5 bar.

Round the corner the south easterly feels a bit more than the predicted 8mph. Perhaps the tall cliffs channel and accelerate the wind along their face. At least it should make for a good sail back.

Heading southeast, I can’t help but feel a bit exposed out here; open sea to the right, rocky beach below a steep, crumbling cliffs to the left, and lethal ledges lurking ahead. What next – fireballs falling from the sky? But away from the corner the seas settle down a bit. The Igla cuts through the headwind at around 3mph.

Nearer the cliffs the water turns green over the clay ledges not far below. But bigger waves rise up occasionally so I prefer to stay out which means I see less. As there are no sea caves to paddle into on this stretch and no skerries to paddled around, in a packboat I decide this unusual area might be more interesting to explore at low tide. You can easily hop in and out of an IK or packraft and wander across the ledges which few people ever access, looking for ammonites and other curiosities. Next time I’ll know.

Otherwise, with linear cliff paddles, in a kayak this Jurassic Coast can be all or nothing. You either commit yourself to a full run to the next normal take-out, or go somewhere and come back.
It’s only 3.6 miles to Chapman’s Pool, but I wasn’t ready for that today. (I packrafted it in 2025). As it is, once there, with a 4-metre boat on your head it’s an unrealistic take-out up a 400-foot climb over a mile to the nearest parking.

It’s the same at the next possible take-out at Dancing Ledge. We checked that out on midsummer’s eve. In calm conditions it’s an easy enough landing providing the lower ledge is exposed, but you’d then need ropes to haul an IK, either inflated or rolled up, up a 15-foot scramble (left) before another steep walk up to Langton village via Spyways Barn. One for a packraft noseabout on the next calm day.

Handy online marine chart for depths.

As it is, Dancing Ledge is on the far side of St Alban’s Head where the tide can kick up a bit (left). Good timing and some nerve are required, even if a kayak can tuck in close to the shore inside the race. This is why Mark R says in his South West Sea Kayaking book. [Kimmeridge to Swanage is 19km and …] “… a commiting trip with big tides races and few opportunities to land. This also happens to be the author’s local (and favourite) paddle.”

View from above, give or take.

Back to the present. Lured by a curious triangle jutting up from the stones, I park up on a narrow beach and hop out for a bit on a look around. This is Clavell’s Hard, site of former shale mining.
At ordinarily inaccessible spots like this you’re bound to find something interesting.

Like a beached red plastic ‘fake clinker’ dinghy.

Anywhere near seaweed there are masses of aggressive ‘sea-horse’ flies. The other week nearby Weymouth beach was blanketed in this kelp which soon started rotting during the hottest month ever. ‘Clear it away! cried the holidaymakers. ‘Stop your whining; it’s a natural phenomenon!’ responded the local council. ‘Get a grip‘ suggested Springwatcher General Chris Packham. Buckets and spades were flying and Trip Advisor turned molten with rage.

“This decision [to ignore the seaweed] supports our commitment to preserving the ecosystem’s integrity and avoiding any potential harm that may arise from interfering with its natural course.” chirped the council unconvincingly. A week or two later later they caved in and cleared the beach. Honestly, it’s just one scandal after another these days.

Compared to northwest Scotland, I’m surprised how little fishing detritus there is here. Are southern fisher-folk more tidy? I help that effort by snagging a superb, self-draining crayfish crate-bench to add to my collection.

I approach the mysterious shark’s fin.

It looked like the upper half of a retractable drop skeg (fixed rudder) with its mounting plate, similar to kits you can buy for hardshell sea kayaks (left), except it weighed tons, not ounces. I thought it might be off some old wreck.

You can see a pivot pin up front. A cable might have winched it up and down. But then any ship that size would obviously have a rudder. Who knows, but I now think it’s abandoned mining junk.

The fin made me think of the SS Treveal which broke in two on the ledges about 1.5 miles southeast of here in January 1920. The Belfast-built steamer was on the return leg of its maiden voyage from Calcutta to Dundee, and had left Portland earlier that day where someone observed that the too northerly heading was inauspicious.
Most of the 46 crew drowned when their lifeboats capsized near the shore. It’s said the tug which came to salvage the cargo also sank alongside. There’s no trace of the Treveal now, even on marine charts and wreck maps. But how do you dispose of a 5000-ton steamer snapped in two? Bit by bit I suppose.

It’s unlikely subsequent storms washed that huge hunk of angular metal a mile and a half to the base of this cliff. More probably it was placed there by shale miners. There’s more on the SS Treveal on Ian West’s geological pages here (scroll to the bottom of the long page).

I wander into a nearby cave, perhaps excavated during the ‘Blackstone’ mining era.

Inside I see just how friable this oily shale is. I can easily peel bits off.

Underneath Silurian millipedes inhabit the tiny cracks, feeding off microbes that feed off the oil. Probably.

Time to head back. I’m all fired up for a good sail with the tide.

Benign, weed-covered ledges lurk not far below. On the far horizon the chalk cliffs of Mupe Bay, just next to Lulworth Cove. Might try there next, but the army firing ranges restrict weekday access. We’ve been hearing machine gun fire all week; Ukrainian soldiers getting trained for the front line.

I throw up the sail but it’s not happening. I creep along at barely 2mph. Maybe I’m too far out (left) and the wind got intensified near the cliffs.

I paddle back to the corner of Kimmeridge Bay…

And carry on to the other side where waves are breaking off Broad Bench ledge. On the left horizon is Portland Bill dangling below kelp-clad Weymouth.

I turn back to the jetty, de-air the Igla a bit and strap it to the car roof.

And though I haven’t really earned it today, I treat reward myself to a seaside seafood basket by the seashore.
