Lulworth to Kimmeridge
Map with most place names

‘Calm… caaaaalm’. It’s what you say to a hyperactive child. But it’s also what you observe as you scan a weather forecast: 3-4mph onshore southerly, backing southeast later. With sunshine too, it could be the Last Good Day of the Summer.
I left my moto just as they’re opening the gate down to Tyneham ghost village. From there the Mrs drives me on up the coast to lovely Lulworth Cove for a sneaky 9am bacon buttie. I do worry about my B12 sometimes.

All calm at Lulworth

“Oh wow!” squealed a little girl as she also arrived with her family at Lulworth beach. And you can see why; it’s an amazing natural feature which, long with others help make Dorset’s Jurassic Coast a UNESCO site. Within an hour the renowned amphitheatre would be standing room only but hey, it’s August on the South Coast; if you want a lone beach, pack a mac and go to the Outer Hebrides.

Red shaded area is army firing range which – land or sea – is usually closed.

Today’s plan was head east 9km to Kimmeridge Bay as I gradually joined the dots packrafting Dorset’s Jurassic Coast.
This time last year Barrington and I sailed here from Ringstead Bay near Weymouth, before getting sent into Lulworth Cove by a patrol boat. The following eastward section of coast is an army firing range that’s only open to the public on weekends or throughout the August holiday season. And even then, some landing spots are closed and inland you have to stick to the paths in case you step on or pick up an unexploded bomb. Tragically that happened in 1967, though thankfully only once and as a result, today warning signs along the footpaths are everywhere.

Leaving Lulworth

Once out of the cosy Cove, the first section should be easy enough, but if not I could hop out at Warbarrow Tout, walk a mile to the bike at Tyneham and ride home. Continuing all the way to Kimmeridge depended on confidence and energy levels, and how the sea actually looked once out of the sheltered Cove.

Today I’ve remembered everything, including my repaired Multimat floor pad. All you need is to get into a routine. And as I set off towards the Cove’s mouth the TXL definitely has its glide on. I have two hours before the tide turned and the wind with it, but right now the boat felt great. I even remembered to pull up my knees straps, and felt nicely connected between the TXL and my paddle blades

Towards Mupe Rocks I had the odd sensation of offshore waves bouncing off the cliffs – it made getting close tricky. I see on an online marine chart (below) the seabed drops off quickly here so the swell just rolls in and boings back out.
They say there’s a petrified tree here somewhere – or ‘Fossil Forest’ in over-heated tourist-speak. But I learn later it’s by a path on the cliff top where there are also periodic radars (left) and other sinsiter MoD installations.

Mupe Rocks from the path

Mupe Rocks turn out to be rather ordinary remnants of fallen cliff, not like the gleaming white chalk stacks I paddled last week near Old Harry. With no interesting arches or caves, I thread about but they’re a bit disappointing.

Mupe Rocks

Seaweed streams reassuringly eastwards with the rising tide, and as I round the corner Mupe Bay opens up, revealing half a dozen moored sailing boats. Behind them rise the steep chalk cliffs which you can see for miles down the coast.

Mupe Bay and Warbarrow, a day or two later.
Landslide

I wonder about putting ashore at a gap in the cliffs called Arish Mell because I can. But perhaps I can’t, even in August, if I have interpreted the map warnings correctly.
Behind the beach I spot some huts, shipping containers, pickups and activity. As it is, my equilibrium is disturbed by some strangely large waves rolling in across the middle of otherwise calm Warbarrow Bay. A submarine shelf? They’re not crashing ashore as far as I can see, but I decide to stay out in the Bay.

Arish Mell gap
Activity on the Mell

Turns out Arish Mell is off limits 24/7/365, using the proven UXO gambit which didn’t seem to be bothering the chappies ashore today.
Another possible reason may be that from around 1959-1990 give or take, ‘slightly radioactive effluent’ was piped out here from the former Winfrith nuclear research facility a few miles away near Wool. They’ve been decommissioning Winfrith ever since and we should be grateful that with much effort they saw fit to extend the outfall pipeline two miles out to sea. You can see the pipe on that marine chart above. Coincidentally, this week Japan started doing the same thing at the damaged Fukushima reactor, raising the ire of Chinese seafood enthusiasts. Meanwhile, this well-produced 1959 Atomic Energy Authority promotional film describing the pipeline project seems very proud of itself.

So I set course for the conical headland of Warbarrow Tout at the far end of the Bay. The sinister waves subside and something else changes: the TXL glides across the smooth surface effortlessly as I am able to draw a long, slow, kayak-like paddle cadence, not the usual thankless spinning.
Later the GPS data revealed the combination of windless conditions and the Multimat helped the raft skim along at up to 6.2kph or 3.8mph. I’m not sure it’s ever sailed that fast so, even aided by the final hour of a modest, metre-high tide, that’s quite impressive.

Actually, I don’t know why I’m so surprised. Although I seemed reluctant to admit it at the time, the first time I tested the TXL with the Multimat in the Summer Isles, the evidence was right there (left), even if it wasn’t night and day.

Approaching Warbarrow Tout

As I neared the Tout I was anticipating some sort of disturbance from an eddy being pushed out by the eastern hook of the Bay. Sure enough, the TXL passed over a patch of incongruous clapotis without breaking it’s stride, but as I moved on past Pondfield Cove (a mini Lulworth) something changed again – the boat seemed to slow to a crawl. The coastline was creeping along but a check the GPS only registered a slightly slower speed.

Warbarrow Tout and Gad Cliffs beyond

As usual with winds, other anomalous currents and flotillas of irate pirates, I wondered if this would set in or get worse all the way to Kimmeridge, with get-offs but no take-outs along the way. I decided to carry on below the Gad Cliffs to the prominent Wagon Rock and if nothing changed, I’d turn back and walk out to Tyneham.

Gad Cliffs. Dorset’s cubist Mount Rushmore

But by Wagon Rock the countercurrent had subsided and the GPS later showed I resumed the steady 6kph pace. Sea paddling alone an inappropriate boat makes you more alert to minute changes in conditions which a sea kayak would carve through with barely a shrug. I later wondered if it was possible the eddy from the hook formed by Warbarrow Tout could draw back or suck in a current ‘beyond’ itself, as shown below. Who can fathom the mysteries of fluid dynamics.

Beyond Wagon Rock the grey sweep of Brandy Bay‘s oily shale cliffs plunged down to the sea. Up ahead I was reassured by the sight of Clavell Tower, just 3km away, marking the far side of Kimmeridge Bay. Less comforting was the breaking water between me and it: the ledges of Broad Bench spotted when I paddled the Igla here a few weeks ago. It would be alarming to have one of these rise up on you out of the blue (below).

Sneaky wave

As always, the solution to such unpredictable seaside disturbances was to paddle further out, even if the instinct (and interest) was to hug the shore. I aimed for the distant St Adhelm’s Head and safely rounded the churning maelstrom of Broad Bench, with the bedrock visible a few feet below. That done, the crossing was in the bag and I worked my way towards the beach where crowds were streaming down to the shore with their dogs. Nine clicks covered in less than two hours from Lulworth. Not bad.

Brandy Bay in a gale.
Interesting shelf

A few weeks ago we walked the coast from Tyneham on a very windy day. At low tide the ledges at Brandy were a froth of white foam (above). Today, walking back 4km to Tyneham, the Long Ebb shelf delineating Hobarrow Bay was already emerging from the retreating tide. Looking back I was reminded the nearby big shelf (left) behind Broad Bench was worth a nose about for fossils or dubloons, even if MoD poles discourage this and you can only access it by boat. It’s one for next time.

Above Tyneham looking back to Mupe Bay

Midday and Tyneham car park is already packed. Another section of the Jurassic ticked off or recce’d for another pass. Hopefully there’ll be a chance to do the 6km from Kimmeridge to Chapmans Pool before we roll up for the winter. That will leave the two points of St Adhelms and Durlstone for the next caaalm day.

Packraft air pressure

Packboat pumps
Flextail Max pump

What air pressure does a typical packraft run?
1 psi, 1.5, 2.5?
Answer at the bottom of the page.

Air bagging. Air bagging. Oh isn’t it wild?

Most inflatable devices come with an air pressure rating at which they perform best, including inflatable kayaks which run from 2psi/0.14bar up to 10psi/0.7bar in drop stitch.
On the cheapest vinyl Intex or Sevylor dinghies, as well as slackrafts there won’t be a number, instead you get a ‘stretch gauge‘ (left). With a Sevy you keep pumping until a sliding black tab settles between A and B; your squishy slackraft is probably now at less than 1psi but is good to go. Add a bit more air to try and make it feel less of a water sofa and the thing will burst a seam. It may do that anyway if you give it a week or two or look at it too long.

Right from the start packrafts never had air pressure ratings. You just aired it up with a flimsy nylon airbag (above) until you couldn’t get any more in. The airbag idea was surprisingly effective once you got the knack, and the bag weighed next to nothing. You then unscrewed it without trying to lose any air, quickly screwed on the cap, then topped off by mouth via the separate twist lock elbow valve (left) with all you had in your lungs. The more you blew the firmer you boat became – and that definitely made a difference to response on the water. It helped if you didn’t smoke and played lead trumpet in the local jazz band.

Once on the water all inflatable boats cool down and the hard-won air pressure inside drops a bit so you have to top it up again to get the boat firm.
What was the air pressure? As much as possible but what did it matter as you couldn’t overdo it with your lungs. Stronger lunged paddlers and opera singers paddled firmer boats. And anyway, such very low pressure would be difficult to measure with a normal handheld manometer.

These days most packrafts use simple and effective one-way Boston-type valves (left) which screw off for a wide open ‘fast inflation’ port for airbagging, but have a one-way valve built into the cap for topping up, just like a car tyre. What goes in, stays in so you can build up pressure and get the boat good and firm. No more crumby twist-locks and undignified topping up by mouth.

Better still, inexpensive pocket electric inflators like Flextail (above left) do the job of airbagging while mini handpumps (above right; adapted from party balloon inflators) can do the important topping up without giving yourself a lung hernia. But what’s the air pressure!? Who cares, it’s better than it used to be provided you could pump the handpump with all you had – I find it takes 100 jabs. A Flextail or similar will burn out long before it can get close to a handpump’s final pressure.

Tip: all these pumps are handy but I always leave an airbag in my packraft’s storage pockets in case the Flextail packs up or I forget it. Otherwise it will be a lot of blowing or handpumping to air a boat up. And with a Boston-type valve as above, a short section of half inch garden hose makes inflating by mouth much easier should you’re topping-up handpump pack up too.

Kokopelli and French-made Mekong packrafts (and maybe others) feature a RIB-style Leafield D7 push-fit inflation valve. That’s push-fit as opposed to more secure bayonet fitting as on proper IKs and iSUP boards. It’s what Gumotex IKs used years ago and is actually not a bad idea on a packraft as the pump nozzle on the end of a hose will blow off the valve as pressure climbs, meaning you have to try hard to over-inflate the boat.

Black boat and Englishman

But these one-way valves have now made over-inflation a possibility, and we know how that can end. However, one thing we’ve learned with TPU packrafts over the last decade or two is that it’s virtually impossible to burst a well-made packraft using a human-powered pump, even a high-pressure iSUP barrel pump. You would really have to go at it or leave a fully inflated black boat out in the midday sun. The fabric and simple but strong sewn and heat-welded assembly spreads forces equally across the single chamber hull ring. So much so that MYO packrafts have become a thing for individuals with a big table and a sharp pair of scissors.

With a D7 valved packraft you could use a handheld manometer (left) with a push-fit adapter to read the boat’s pressure. Such manometers have a pin in their throat which pushes open the D7’s sprung valve stem just as the gauge body seals around the valve housing, so getting get a live pressure reading.

I don’t have a D7-equipped packraft at hand, but I do have a Bravo Alu 4 R.E.D barrel pump fitted with a 14.5psi/1 bar inline manometer (left). With an adapter jammed in the Boston’s threaded port I ought to be able to get a full-pressure reading off my Anfibio TXL.

I’m guessing about 2psi / 0.14bar to get a pinging firm TXL. It’s what my early Gumotex IKs used to run, using the now obsolete footpump. When the Seawave came out, rated at 3.6psi/ 0.25 bar, that was quite a revelation, though before that I ran a 4.3psi/ 0.3bar Grabner Amigo and you could have battered down a wall with that boat, proving that rigidity didn’t require drop stitch panels as long as the boat was solidly assembled. At Grabner prices, you’d expect that to be the case.

Back to the test. And the answer is…. just 0.1 bar or 1.4 psi. And this was with the TXL as tight as a drum such as I could never manage with the balloon handpump but might have with a K-Pump Mini.
Now we know.

TXL; Packrafting Old Harry (Swanage)

Packrafting Swanage
Kayaking the swanage Stacks

On Google Maps an ebbing tide spins out an eddy of sand out into Swanage Bay.

Swanage to Studland past the Pinnacles is one local paddle I don’t mind repeating. In normal conditions it’s the most dramatic, easy paddle I know on the Jurassic Coast, sheltered as it is from the Channel swells. Today I’m going to make a loop of it: packraft round to Studland and walk back to Swanage over the downs (map left). All up about 11km which should be doable in the 4 hours I’ve put in the meter.

It’s always further than it looks to the north corner of Swanage Bay at Ballard Point, so I sit back and let the wind do the work. But apart from the odd gust, it doesn’t feel like 12mph – like sailors say, it’s either never enough or too much. GPS recordings later reveal no records were broken.

Leaking Multimat

Around here I was expecting to top up or ‘temper’ the TXL’s sagging hull with the handpump once the air inside had cooled down and softened following 20 minutes immersion (as explained on the previous outing).
But remembering the Multimat floor mat this time, there was no tell-tale crease in the TXL’s sidetubes, even with a slow leak I noticed at the beach from one of the mat’s seams (left). So the mat must do the job in supporting the hull, even if, sat higher, I felt a bit wobbly on setting off. The mat’s not been left out in the sun, let alone sat on since I filled it in advance, but I’m not surprised a leak has sprung, with probably more to come; I-beams are weak under pressure but it’s a necessarily lightweight design that still weighs nearly a kilo. You pump the mat up as firm as you dare, otherwise what’s the point; I must have gone a bit far. I’ve picked up similar, wide, I-beam seats from Anfibio with the same damage; all easily repaired with quick wipe of Aquasure sealant.
I know it would need a stronger pump (like my K-Pump Mini), but, despite added cost and probably weight, a 2-3 inch thick dropstitch floor mat – either TPU or nylon – would be a more durable floor mat. The AE Packlite+ packrafts use them.

Round the corner the wind eddies out and drops a bit, and up ahead the big spiked pinnacle is still such a surprise I initially mistake it for a big moored yacht. You’d think I know by now. A couple of sea kayakers are heading the other way, into the tide and breeze. They’re curious about the sail and raft.

I admire their sleek, water slicing craft. I’ve just finished reading Moderate Becoming Good Later, Toby Carr’s attempt to kayak in the 31 Shipping Forecast zones (right) before he succumbed to cancer in early 2022, aged just 40.
He pushes himself hard, starting with Iceland, a lap of some Faroes, out to Utsire island 40km off Norway and the full coast of Galicia [Biscay, Fitzroy], as well Bishops Rock lighthouse beyond the Scillies [Plymouth, Sole, Fastnet, Lundy] before his health collapses.

He reached some amazing places and it reminded me what a uniquely effective boat the modern sea kayak is in experienced hands. Combine today’s lightweight composite materials with inexpensive GPS tracking, satellite comms and ever more accurate forecasts, and radical paddles like the ones listed above become possible if you have the nerve, the strength and the wits to know when to wait it out.

But I’m bobbing along in a packraft, also a great tool for more amphibious adventuring. More kayaks come through, including some SoTs and all clearly unpatriotic types disinterested in how England’s women might be doing in today’s World Cup Final. Luckily we can look forward to days of analysis and debate when we get back ashore.
As I near Old Harry I tuck the sail under the deckbag and wait for some paddle boarders to squeeze through on their knees before threading all the arches I can; there must be over half a dozen here, not all full or wide enough for the TXL at the current tide level.

No PFD?

As this news report from a few weeks ago shows, it doesn’t always end well for paddle boarders taking the 1.2-mile run from Studland beach to Old Harry’s. But at least the guy rescued after 7 hours was wearing a PFD which I rarely see among paddle boarders. It’s just never become a custom, same as with Thames rowers. I don’t get it myself but maybe the lack of required clobber is part of iSUPing’s appeal. It is of course easy to crawl back aboard so out at sea – always a sketchy idea – an ankle leash is probably more important.

Arch bagging at Old Harry Rocks

That done, all that remains is a paddle along the northern lee of Ballard Downs to a busy beach all of 6 feet wide, pack up and a walk back over the Downs to Swanage.

Looking back north from Ballard Downs to Studland Bay and the entrance to Poole harbour.
Turn round and Swanage Bay lies up ahead.
It’s that time of year.

After the Gale: Packrafting with the Teignmouth Beast

An old mate got in touch to tell me he’d bought himself a top-of-the-range MRS R2 Barracuda Pro and heck, even my packrafting book. He’s in Devon and I was in Dorset so I suggested we meet up for a Yuletide splash-about. Back in the day we were desert bikers; now we’re packrafting pensioneers.

Like some do with a new activity, Phil had got stuck right into his MRS and had already paddled to Dartmouth with his Brompton bike (left), something over in Norfolk, then scared himself further up the rain-swollen Dart from Buckfastleigh to Totnes, noting ‘it’s amazing how dangerous the big branches [and fallen trees] are…’

Tell me about it. If it’s not weirs or camo-&-beard anglers spitting poison darts, it’s deadly sweepers blown down by winter storms. I never quite got round to doing the Dart in my fearless prime, such as it was, but I hear in winter it’s one of the Southwest’s whitewater classics – a bit serious for me now. We settled on the Teign out of Newton Abbot with our respective bangers parked at either end.

If nothing else, we ought to have a good backwind. The previous night had peaked at around 50mph, but by dawn it was tailing off to half that, with the usual gusts at +50%, single-digit temps and showers. A good day for a drysuit and a stable packraft.

Some quick stats on Phil’s noire ‘cuda: 3.6m x 99 wide with 217cm inside and up to 7.6kg with the removable deck, two seats and internal storage, all for a hefty £1750. Compared to my TXL, it’s 80cm longer or nearly 12 feet in old money; our Micra’s shorter than that! It’s also 10% wider than the TXL, about 35cm longer inside so loads of room for 2 adults. Solo/no deck it gets down to 5.6kg alongside the TXL’s 3kg.

We drove around Newton looking for parking and a put-in. Opposite the racecourse and over a broken roadside fence we found a spacious river bank just at the Teign’s tidal reach. By the time we set off we were in the middle of a 3.5-m ebb, midway between springs and neaps.
Either way, like the Frome the other day, the Teign was ripping along at a light jog and before I’d got myself untangled from my gear I was 75m downstream. I thought I’d finally got to grips with keeping it all in one bag, but Today’s Forgotten Item was my seat base [forehead slapping emoji]:
Gear drifts apart; the centre cannot hold. Mere forgetfulness is loosed upon the world‘. By chance I had a spare Anfibio Bouy Boy which did the job as a seat cushion.

The Barracuda has the same distinctive prow design as my old MRS Nomad which was a fast solo packraft, what MRS call StreamLineSL. These prows take up nearly 1.5m in the R2 which explains the massive length while still having a lot of room inside the boat. There’s probably enough buoyancy for four people and a caribou calf, with room for all their gear inside the ISS hull storage.

Before we knew it we’d passed under the A380 bridge and were out in the wide tidal estuary. The predicted 20mph winds came barrelling down the channel so I couldn’t resist flipping out my WindPaddle. With the Barracuda’s mooring line clenched in my teeth I managed the sail while Phil’s phone recorded 8 knots, obviously helped by the falling tide.

There were a few forceful gusts and the fetch kicked up towards the end, but the TXL and Barracuda shrugged it all off and my transverse bow sprit (left) did a great job of steadying the straining sail. I think the MRS has wider attachment points on the bow so may not need it, but I’m sure Phil will be buying a PackSail if Anfibio can do him one in black. He did.

Things got a bit chilly out in the deeper water and I noticed my TXL was creasing a bit at the sides. It’s been so many months since I last used it I’d forgotten high-volume packrafts need a second top-up a few minutes in to get good and taut. It didn’t seem to affect speed, but like properly laced shoes, taut feels better. That’s one good thing with Phil’s black boat; it auto pressurises in the pale winter sun. While we sailed, he tucked into his lunch.

The Teign estuary is actually not too industrialised. Under the last bridge The Salty sandbank was starting to emerge from the chop and as we curved round to the river mouth the sidewind pushed us into moored craft caked in algae. At the narrow outlet a rip of bouncing clapotis was jiggling out to sea and on the beach someone was striking poses for their Insta feed.

A little over an hour for 5 and a bit miles, just about all of it sailing both boats. It was interesting to learn that the WP could sail two big boats without much loss of speed. Staggering ashore, it felt odd not to be arm knackered, but once I got over that we headed into the deserted seaside town in search of the legendary Teignmouth Beast. That’s a local XXL pasty, not the jet-black MRS Barracuda.

South West Sea Kayaking guidebook

I’ve done a few IK paddles in Southeast England between Rye and Portsmouth, but the Sussex and Hampshire coasts aren’t that inspiring. So it’s about time I started exploring the far more interesting and much more extensive Southwest Coast. From the Isle of Wight to Cornwall and back up to the Severn there are scores of inshore excursions possible in an inflatable. Just as in the far northwest where I mostly sea paddle, all you need is a fair tide and paddle-friendly winds, the latter a bit less rare down south.

In a blobby packraft? You cannot be serious!

So in the face of predicted moderate winds I cooked up a 50-km Jurassic overnighter from Weymouth to Swanage in Dorset. I’m pretty sure they opportunistically rebranded the plain old Purbeck or just ‘Dorset’ coast as the ‘Jurassic Coast‘ soon after that 1993 movie and haven’t looked back since.
Like much of the Southwest coast, the beaches and country lanes become a logjam of holidaymakers on a warm summer’s day. On the water, our paddle would pass below sections of cliffs a couple of miles long and take us to the famed landmarks of Lulworth Cove, Durdle Door arch (top of the page) and Dancing Ledge. We could even carry on back north past Old Harry’s Rocks and across Studland Bay right into Poole Harbour to catch out trains home.

TXL at sea

Compared to using regular (solo) packrafts, my confidence in my TXL for sea paddling is a revelation. After all, it’s still just another blobby, single-chamber packraft. It must be a combination of the added size giving a kayak-like perception of security (as I found in my MRS Nomad), as well as the responsiveness and speed from a longer waterline and, I now recognise, the sometimes noticeable added glide from the Multimat floor. There’s also the fact that paddlechum Barry was up for the Dorset run in his similar MRS Nomad, making this untypical packraft outing less daunting.

Lulworth tides – all or nothing (of not much).
Modest, two-metre tides off Purbeck

For some bathymetric reason – possibly the Atlantic tidal surge backing up in the Straits of Dover, plus hidden offshore shelves – the tides off the east Dorset coast are very odd: they can rise or drop all day, but have a range of just two metres, about as low as it gets in the UK. That ought to mean moderate ebb flows pushing up against prevailing westerlies, plus we were heading into neaps. And while often cliff-bound, if we stayed alert to escape routes we could easily bail and walk or climb out with our packrafts.

East of Lulworth Cove the Jurassic Coast‘s bucket & spade Babylon is interrupted by a 5-mile wide Danger Area – an army firing range. This was probably not one of UNESCO’s criteria for World Heritage status, but the SW coastal path also gets closed for a similar distance. Barry’s Reeds Almanac had a page or two on this (left), as well as useful tidal flow charts (drops to the west; rises east). I left it to Barry to call the ‘0800 DUCK!’ number, but imagined surely they’d leave the target practice to the off season. In fact they’re all it most of the time Mon–Fri, including an evening session 9pm to midnight: all we had to do was click this.

Early train to Weymouth

With a plan taking shape, I in turn bought a copy of Pesda’s South West Sea Kayaking in the hope of being alerted to local anomalies. I’m glad I did. It turned up with just hours to spare and identified that the run from Kimmeridge Bay round the Purbeck corner to Swanage was a grade up from the easy section from Weymouth. With headlands, submarine ledges and long lines of cliffs, without a foot recce I decided we may be better off skipping this bit.

It’s noon in Weymouth, but with offshores now predicted by late afternoon, we fast forward by taxi to Ringstead Bay, 5 miles in. That first section from Weymouth looks nothing special.
Put in at Ringstead. Ten mph westerlies blowing against an ebbing neap tide.
My Mk2 transverse bowsprit for a wide WindPaddle sail mount to limit swaying in stronger winds.
I’m giving the Multimat floor yet another go too, all the better to skim over the water.
We’re on the water at 1pm, hoping to reach Chapman’s Pool, about 21km away.
But around 5pm winds are said to veer offshore and strengthen, so we’ll see.
We sail at about 5-6kph – not much faster than paddling – but I note my TXL creeps forward about half a click faster than the MRS – must be the stiffening Multimat.
Propelled at paddling speed by his inflatable AirSail, Barry casually checks his investment portfolio.
The cliffs below Chaldon Downs. At times we paddled as we sailed to make less work for the wind.
Forty five minutes in, I pull in the sail and line the TXL up to thread Bat’s Head arch.
Note how the layers of chalk beds here have been pushed up to nearly vertical.
Give it half a million years and Bat’s Head will be as big as nearby Durdle Door.
Approaching the famous Durdle Door arch alongside a crowded beach.
The TXL still weathercocks a bit under sail; I keep having to steer hard inland, but the bowsprit ‘stick’ limits the sail’s ability to twist. Or maybe the wind’s bouncing off the cliffs and blowing us offshore a little.
Sitting further back to weight the back end over the waves may help.
Sunbathers watch spellbound as Barry smoothly ‘Durdles the Door’ – a Southwest kayaker’s rite of passage.
The Door has been durdled. Some claim ‘Dorset’ (formerly Wessex) was named after this famous arch.
In high summer young bloods jump off the 60-metre arch. Appropriately, it’s called ‘tombstoning’.
Near the entrance into Lulworth Cove things get choppy. Sat high on the airmat floor, if I feel unstable I can easily let it down. As we head through the Cove’s narrow neck a patrol boat circles back and instructs Barry we can’t carry on east; the army ranges are firing.
‘I thought you said you were going call them, Barry? You had one job to do…’
‘But you said they hardly ever do this on a balmy, July’s day!’
And so it went on…
A salty-eared boatman tells us the army pack up about 5pm, about 2.5 hours from now by which time the offshores may be on us as we cross the Kimmeridge Ledges mentioned in the Pesda book.
As we slurp a 99 with sprinkles the odd gust blows offshore.
We can’t even pack up and walk the cliff path; it’s closed too, and so is the B3070 road.
Barry wants to paddle on a 5pm, but I propose we bus to Swanage rather than risk being be left high and dry.
Tomorrow we’ll paddle north towards Poole – or as far as the predicted headwinds allow.
So a paltry 5 miles – but the classic stretch of the Jurassic Coast.
But there’s no campsite till August, so we pitch for free up in Durlston Country Park to the sound of beery revellers and Tuesday-night hoons doing burn-outs along the seafront. What can it be like on a Saturday night?
Six am next morning, a light breeze blowing from the northwest means no condensation ;-))
The Anfibio Multimat passed the sleeping test, too.
I walk a mile south to Purbeck’s corner at Durlston Head to inspect the tidal stream. Two hours before LW, it’s negligible, but further west, St Albans Head just out of Chapman’s Pool is said to be stronger. I must do that walk sometime.
Above, a ferry heads from Poole to the Channel Islands.
Looking back north you just see our tents on Peveril Point,
Ballard Down chalk cliffs and pinnacles stretch out beyond, and Bournemouth’s at the back.
At the cafe we meet Rach and Mark setting off on the final day of a staggering 630-mile walk along the Southwest coast from Minehead in north Devon. Their picture above taken a few hours later.
Meanwhile we prime our boats for the 6.3 miles past Old Harry to Poole Harbour Entrance.
We may carry on to Poole itself, but a strengthening wind may nix that idea.
No sailing today, Barry inches into the light morning breeze across Swanage Bay.
We reversed this trip a couple of months back.
Ballard cliffs in the wind’s lee at glassy low water.
Ballard’s spike, thought by some to be a fossilised Dendrosauraus tooth.
We approach the Pinnacles to the squawk of agitated seabirds.
Arches ripe for threading as far as the eye can see.
But this morning the tide is too low.
And it means there’s a lot of this string-weed floating about. It catches in our skegs but I have a solution.
Leaving Harry’s, Barry’s is a bit of a Lethargic Larry cutting across Studland Bay.
Halfway across, I remove a metre-long, kilo of Swanage string-weed caught in his skeg.
It’s all going nicely until 10.30am when the wind kicks up, then picks up some more.
But the GPS revealed we kept plugging on at 5kph, just with a lot more effort.
As Barry observed, it was a slog but good to know our packrafts can progress against this sort of wind.
With brain-out jet-skiers, sailboats, motorboats, working boats and the rattling Sandbanks chain ferry, we have to time our crossing across the busy vortex of Poole Harbour Entrance. Hitting 8kph, we cross a sharp eddyline where the incoming tide clashed with still-draining Poole Harbour. Barry hops out quick before the chain ferry trundles back. (Turns out it’s actually free for northbound pedestrians).
From Swanage to Sandbanks, followed by a 90-minute walk to Poole station for the train home.

Anfibio Sigma TXL • Top 10 mods & tips

Sigma TXL main page

Revised Summer 2023

I’ve owned the Anfibio Sigma TXL for well over a year now and am now on my second TXL+. I’ve done several day trips two-up, solo and some sailing. They’ve all helped give me ideas on how to refine the boat to my needs.
On purchase I got the optional Multimat airfloor, additional foam block seat, paddle leash and use my old Anfibio DeckPack on every trip. I also got a spare skeg patch and mounted a second skeg under the bow – it made things worse.
Here’s an annual reappraisal of the Sigma TXL followed by a list of modifications which have worked for me. Got packraft tips of your own? Let’s hear them.

Spacious solo
Light for its size
Room for 1.9 people
TubeBags very handy, even for day trips
Level solo trim (unlike Rebel 2K and similar)
Multimat floor’s benefits are noticeable (good to sleep on, too)
Broad, thick front seatbase spreads the load: less floor sag when solo
Thicker 420-D floor extension ‘bumpers’ over bow and stern
Variety of set-ups and sitting positions, solo or two-up.

Stock skeg mounted too high (or too small)
Inflatable front backrest lacks support
Optional foam seat block too hard
For me, the paddle leash was inferior to my regular mooring line
A dump valve in the seatbase would be nice (instant deflation)
Reduced floor space when two-up with Multimat (depends on your sizes)


Best Sigma TXL Modifications & Tips

1

Fit a thin foam backrest (+40g) for better support.
Fits with no mods bar some helpful zip-tie slip-rings at the back. Works best with a footrest (6).

2

Fit a skeg mount to the floor so it’s fully submerged. Needed for sailing.
Otherwise reversing the stock skeg improves submergence a bit, or make a bigger one.
[Both skegs shown, only one needed for paddling]

3

Knee straps improve boat connection both on flatwater and when waves get lively, plus they help bracing into a headwind and are handy lifting handles on land. Above is the old Anfibio version which requires gluing on 4 tabs as none of the stock ones line up or are robust enough. Anfibio do a ‘5-P’ thigh strap – even more gluing needed but better for whitewater.

4

Fit protective floor strakes before scratches get too bad (sea shore use; heavy paddler).
Any thick tape will do; I used expensive Gorilla Tape Patch & Go. but actually the TXL sits level, two up or solo, so this is not so clever or useful.

5

There’s a lot of volume in a TXL so a Flextailgear electric pump works away while you do other prep.
Using rubbery, self-amalgamating tape, I adapted a spare nozzle to fit both the Boston valve ports (top).
The soft grey adapter supplied (bottom left) fits the main port but could pull off and fall inside. If you use it, glue it on.

6

I tried a roll-top Anfibio Multibag Footrest but reverted to the simpler MRS footrest I used on my Nomad, with its overlong inflation hose. It creates a flat surface to push feet against for a good paddle draw.

7

Consider Anfibio’s Lite Seat base for two-up only (-176g). Besides being less than half the weight, the curved rear edge gives a little more footroom for the rear paddler compared to the broad, rectangular stock front seat base (see backrest picture 1).

8

The TXL’s frontmost tab mounts are close together. If you’re sailing with a WindPaddle or Anfibio AirSail/PackSail, consider a Transverse Bowsprit (‘stick’) so the sail’s mounts are spread wide. It stabilises the sail which can flutter side-to-side when winds get strong.

9

Initially I wasn’t convinced but now I am: the 900-gram Anfibio Multimat reduces sagging, especially solo, and helps the TXL glide. Yes, it’s another thing to have to carry and pump up, and I’ve already repaired mine once, but one time I paddled at 6kph on a calm sea for nearly an hour which I’m sure was made easier with the Multimat. Why Multimat? You can sleep on it too.

Sigma TXL: seat and sailing sorted (videos)

Sigma TXL Index Page

The winds here have been belting out at up to 40mph for days, but I grabbed a quickie during a lull the other afternoon to try out some final mods.

Foam backrest: much better

My centrally seated TXL is like a small TPU kayak – the missing link, some say – so it needs a backrest that works. I was never won-over by the Anfibio inflatable backrest on the Revo or my boat; it manages to be both mushy and wobbly.
But once on the water it was soon clear that, combined with my Lomo holdall wrapped into a footrest bundle (below left), the foam SoT backrest felt much better. The broader, firm pad spreads across the back supportively and is held up with straps, not thin elastic. Plus being able to press feet side-by-side against a flat, firmish surface, not jam feet into the bow, is also much more comfortable. It felt just like my old Seawave!

I was giving the Multimat air floor one more try. It must do some good and I admit it may have helped replicate the IK feel. And unlike initial impressions, the half-inflated seat base is actually pretty stable sat on the stiff floor, not wobbly as I originally thought. Plus the pad protects the floor from impacts below, and heel scuffing inside.

I did feel again that the TXL skates across the water a little, bobbing on the stiff air floor. This flat-floor effect makes sense on a shortish 3:1 ratio boat and was one reason I thought a front skeg might be helpful (it wasn’t with the stock rear skeg). The air floor lifts the boat a bit higher in the water and the sliding left to right is more from wind and waves than in reaction to paddling strokes (like normal packraft bow yawing). But until conditions get too rough I don’t think it really hampers paddling progress that much. It’s a packraft after all, not a jet ski!

While I had the floor in, I tried the 15-cm thick seatbase fully inflated and sure enough, like Anfibio say, it’s too high and may get unstable on anything other than flatwater, even with my repositioned knee straps for added support (left). That’s why they offer the 5cm foam block (it’s on ebay, fyi). A thinner inflatable seatbase would be less agonising but it seems, like on an IK, the half-inflated stock seatbase actually works fine.

Only one skeg needed

The other test was a skeg repositioned on the floor for full submergence – this is only needed for sailing; the TXL tracks well enough with the semi-submerged stock skeg position and goes OK without one. Had I not seen the selfies (left) and not tried sailing, I’d probably not have noticed.

The afternoon’s glassy calm had turned already. I pushed into the breeze out towards a low-tide skerry just off Tanera Mor, then heeled round for the mile back to Badentarbet beach and flipped out the WindPaddle. I left the stock skeg in place which was cheating a bit, but I’m pleased to say my earlier problems with weathecocking (stern blowing round, side to the wind) have been solved. No surprise a fully submerged skeg makes the TXL sail as well as my Rebel 2K and MRS Nomad.
This was an important thing to pin down as I want to be sure my bloaty, IK-replacing Sigma TXL has something up its sleeve when the wind allows because, like any inflatable, in the other direction it will struggle as headwinds reach 15-20mph. Sailing still needs constant micro-adjustment, but it’s great to feel a gust tugging at the handlines as the Sigma ploughs a trough through the surf like a water buffalo wading across a mudhole. The boat was definitely hitting 7kph or more at times.

I was also trying an idea I didn’t get round to testing on my narrower-bowed Seawave before I sold it: a WindPaddle transverse bowsprit™. Those cunning Chinese will be copying it on ebay any day now.

TXL vs MRS Nomad spacing

A WindPaddle disc sail starts bobbing madly left to right when winds get much over 10-15mph – it can’t unload the air fast enough. This is a side effect of mast-less downwind sails, but I figured if the bow sail attachments were further apart and more taught, the bobbing might be constrained. You want a downwind sail at the very front of a short boat, but on the TXL thr frontmost mounts are quite close together (compare to a Nomad, above left).
My ‘transverse bowsprit‘ is a stick which extends the sail mounts out to the sides, like ship rigging. I used a foot-long bamboo stick with some Rovaflex loops on the ends and for the weight and minimal faff, I like to think it worked. A bit longer would be better; I have a 50cm rod lined up for next time.
A few days after posting my sailing vid, YouTube thoughtfully directed me to a ten-year old video where a bloke with a hip-wide surf ski had the same idea (above right). Only he managed to zip along at a breathtaking 15kph in a 40kph breeze!

Heading towards shore, again, I aired-down the Multimat but again, can’t say performance deteriorated noticeably. After all, the MRS Nomad manages fine. The stiffening breeze rushed me towards the rarely exposed sands of Badentarbet beach and a short walk home.

So. Good to know the TXL is now largely sorted. Weather-wise, it’s been a wash-out in the far northwest this year, but there’s still enough summer left in the heatstruck south to do some trips.

Sigma TXL: floor-mounted skeg and foam backrest

Sigma TXL Index Page

After various trials I decided for sailing the TXL would benefit with a skeg on the floor where it would be fully submerged except momentarily when cresting bigger waves. The standard position angled on the stern (left) sits too high on the buoyant TXL so doesn’t have much effect, though the TXL tracks pretty well on flat water, with or without the air floor, solo or two up. You can mount the skeg back-to-front (right) for more bite, but I hope tracking when sailing will be greatly improved with a fully immersed skeg. When the wind allows, I want the TXL to be a reliable sailer on longer paddles.

Under the floor stays fully submerged, even with the air floor.

I could’ve simply made an extension to the stock skeg, but decided having two positions for the stock skeg would be less bulky. Like on an IK or a SUP board, the long but shallow Anfibio skeg would work well mounted horizontally under the floor (above, left). I’d already tried a skeg under the bow, but that did not work well at all. Waiting for good glue, I’d stuck that front skeg patch on with Aquasure and was surprised how easily it peeled off with less than a minute with the hairdryer.

Just as I was about to clean the removed patch and glue it on with Helaplast (recommended by Anfibio), I thought super tacky Gorilla Patch & Seal tape would be even easier, using the spare Anfibio skeg patch as a template. But I decided P&S is just thick ‘rubber’ tape suited to sealing, not supporting a knocked about skeg. In fact regular, string backed Gorilla ‘duct’ tape would have worked (a good way to test the idea), and I’ve found lasts surprisingly well on a packboat. In the end I decided the liberated fabric-backed Anfibio patch would be best.

The most important thing is to mount the patch straight along the centre line otherwise you’ll be going round in circles. This is best judged with the boat inflated. After that, it’s the same Helaplast sequence as detailed here. While gluing, I decided to add a couple of tabs low in the front to make the thigh straps hook more effectively over the knees.

The benefit of having two positions for the rear skeg instead of a bigger fin is that you can choose: use the standard position for shallow rivers (if a skeg is even needed) and use the floor mount on open water where wind and waves may push the boat around more, and if you hope to sail in a straight line.


Foam backrest
Sat up front, the stock inflatable backrest (below left) does the job, but in a low-pressure boat, the air cushion just adds more mushiness where you want support. As I say in the book or on Seats: sit on air; lean on foam. There is no advantage to inflated backrests other than saving a bit of packed space (might they also be cheaper to produce?). In this way, regular solo packrafts, where you lean on the back of the boat are better. Seated centrally in the TXL, you need a supportive IK-style backrest.

After a few outings I’ve decided to replace it with a spare foam SoT backrest (below), an idea which has worked well on my IKs for years. IK makers too have a blind spot when it comes to front seats. Today’s price for the backrest on ebayUK is 17 quid (left). Once I ditched the heavy ‘brass’ clips which came with mine, it weighs 200g, only 40g more than the Anfibio item (the ebay one shown left uses lighter plastic spring clips).

The foam backrest fits right on the TXL: the long tapes reuse the TXL’s front buckles and, less well, the rear straps come back through the flat tab mounts. A slide ring would work better here. I could have reused the thin, cinchable elastic cord which came with the Anfibio backrest but I suspect it was part of the problem (and thought so on the Anfibio Revo too). Counter-tensioned, non-elastic straps attached to a firm panel add up to better support. Up to a point the thinner foam backrest also makes more room behind it, too. And I won’t miss deflating the stock backrest to save on packed space, neither!

As the calendar flipped into June the crap May weather – worst for decades locals say – had finally broken, and northwestern Scotland sits under a High with cool, light winds and blue skies. After weeks of the opposite, it can all look a bit miraculous. The other day we climbed Ben Hope, Britain’s most northerly 3000-footer. It’s a short, steep climb, and coming back down I was sure pleased to lean on my packstaff (right).

Ben Hope and Britain’s north shore.

Back home, paddling the southern edge of Enard Bay in an arc from Garvie Bay around to Achnahaird beach (left) was another easily realised sea packrafting outing. It’s also our favourite local half-day walk and with today’s strengthening northerly breeze, I ought to be able to sail down into Achnahaird, wade up the stream to the twin freshwater lochs, and carry on sailing nearly all the way back to Badentarbet. All up that would be about 18 kms of paddling and walking.

It’s a muddy kilometre’s walk from the road bridge down to Garvie beach which, unlike popular Achnahaird, is usually deserted. I did carry my old Grabner IK down on my head one time for a paddle to Lochinver, but a packraft in the pack is so much easier. This car-free and approach/portaging ease was part of the rationale in putting all my eggs in the TXL basket and flogging the Seawave.

Even before I reached the shore it was clearly a bit windier than the predicted 6mph, but as long as white capped waves held off (the easily spotted warning sign for inflatables) it should be OK. The chilly northerly coming off the sea was steady; less gusty (or so the forecasts suggested) so I was glad I grabbed the dry-suit last minute.
As you can see from the Google image above, the rough shoreline and reefs can kick up some breakers, but if it all got a bit much I knew plenty of take-outs to join the Mrs who was doing the walk and taking photos from above.

Skeg effectiveness
Anfibios mount the skeg sloping down on the hull’s short stern. Selfies I’ve taken on previous TXL paddles show the skeg halfway out of the water, unless the boat is very heavily loaded. The air floor lifts the boat higher still.
This was not an issue in my rear-weighted Rebel 2K single seater where I pushed the back end down. On the level-trimmed and more buoyant TXL, the skeg is ill positioned or too small.

Fitting the skeg backwards puts more in the water, but sticking another mounting patch at the back of floor sheet like an IK (above right) is fully effective. People ask: would the lack of inflated skeg support be that bad without the firm backing of the air-floor or a rear paddler’s seat? No; and the long, low stock Anfibio skeg is just the right shape.

Mounting another skeg patch on the floor is a bit time consuming is what I ended up trying so I can keep the stock skeg. Today I’m trying a spare Gumotex skeg (right) whose slip-in mount system the Anfibio skeg copies, but which has a deeper profile putting more plastic in the water. It’s only less than half a hand’s worth, but is worth a go before fabricating a skeg extension or repositioning it.

Today I’m also trying my longer, smaller-bladed, 230-mm Camaro sea-kayaking paddle more suited to steady cruising into the wind than the over-sized, white-water Corryvreckan I’ve been using so far. Initially I can feel the paddle’s extra weight, but that’s soon forgotten which suggests the slimmer blades are just right. Progress is a bit sluggish into the northerly, but I’m getting the feeling it’s always like this with the bloaty TXL until the arms warm up.

I wonder if coming round the point and turning west into Camas a Bhothain (‘bothy bay’) may get a bit lively, but the TXL takes it all in it’s stride. It’s easy to spot where waves break over reefs and, sat low on the broad, 15-cm-thick seatbase, stability is never an issue and for a packraft, the TXL tracks well across the side wind and waves, perhaps helped by the Gumboat skeg and my masterful technique.

It’s only 4km beach to beach and soon I’m threading through the western Rubha Beag skerries and turning south with the wind for Achnahaird.

Out here in the open the waves are bigger with the odd white cap rolling past, but incredibly the boat feels fine. In a normal solo packraft I suspect I’d be a bit freaked out. The bigger boat makes you feel less vulnerable and the high sides keep the splash out and don’t seem that affected by ~10mph side winds (something I discovered on my first sea outing in Dorset).

I paddled out into Achnahaird Bay (or so I thought) to get a straight run for the beach, then flipped out the WindPaddle. Only things don’t go so well. Just like the other day when I blamed the front skeg, the TXL is weathercocking (back coming round, below). This time I blamed a too shallow skeg lifting out on wave crests at which point the wind pushes the untethered stern around – the boat pivoting around the sail’s ‘mast’ on the bow.
I’ve had this before sailing a IK on Ningaloo Reef in northwest Australia (tall-sided Ik and too short a rudder for the winds). In the TXL my central ‘kayak’ rather than rearward ‘packraft’ seating position doesn’t help. The (loaded) Rebel 2K sailed fine in similar conditions; so did my unloaded Nomad S1 one time, as well as Barry’s loaded Nomad last year in Knoydart. With its skeg on, the MRS Nomad sailed well, with or without a load. Along with its pointy ends, I put that down to its fully submerged skeg.

Meanwhile in the TXL you can see my annoying zigzagging track on the left. Hoping to slice across the bay like a blue-fin tuna, it was all a bit frustrating, but I inched in the right direction quicker than it felt and was pretty sure weight distribution and skeg depth were the culprits. And in fact I saw later the GPS was logging a steady 6kph, it just wasn’t the steady linear progress I’ve had sailing other packrafts.

Once at Achnahaird I paddled as far as I could up the burn running alongside the beach, then hopped out and waded upstream – easier than carrying the boat in the wind.

Near the road junction it’s a 2-minute carry over to freshwater Loch Raa where I hoped the lower waves would give the skeg some traction. But it was the same zigzagging progress. Waves combined with a shallow skeg were not causing the weathercocking (as they had in the Bay). So the problem had to be weight distribution. I remembered a canoeing adage: “sit up front into a headwind; sit at the back downwind“. You are the flagpole from which the boat should trail downwind. After a short portage over into Loch Vatachan, I sat right at the back and progress did seem a bit straighter, as the GPS tracklogs below show. I was no faster: 6kph downwind and 5ph on the ‘off-wind’ zags, but there was less zigzagging.

Left: sailing sat centrally. Right: sat at the back. With a bigger skeg I’m hoping for a straight line.

By the time I reached the south end of Loch Vatachan to pack up, the wind was fairly brisk (left). Packraft sailing should be better than this but moving to the back of the boat to enable reliable tracking under sail is not so practical. The answer must be a bigger or repositioned skeg.


A couple of days later we went for a short paddle in a reasonable sailing wind. The stock skeg was on back to front (right) and with the Mrs’ added ballast I hoped it might bite under sail.
Unfortunately it was the same story of the stern coming round even if the speeds were again OK. On a beach we went for a wander and found a nice bit of broken plastic fish crate. We’re gonna need a bigger skeg.

During the stop I took the TXL out for a spin sat in the back. Of course the bow was up in the air and yawing like a giraffe, but it was quite a revelation to have a spacious boat extending out in front of me like a kayak. My front seatbase made a spacious footrest and I could lean on the back like a normal sized packraft. Sat in the back, as a way of touring or bikerafting, a bike over the bow and baggage in the front would correct the trim a little. And with the 200 litres of dry storage capacity inside the TubeBags, you could probably move house with the TXL.

We paddled the last mile to Badentarbet with me in the back. Again this felt much more comfortable for me – it must be the ability to lean on the stern. Meanwhile the Mrs said she felt no more cramped than the back. Yes the trim was still off (left), but so it always was on my 2K and I got around in that with no problems.
That’s the great thing with the TXL: there are all sorts of ways of using it.
