Packrafting the Swanage Pinnacles

A recent picture on BBC News of David Attenborough plugging his new Ocean film (or lamenting the ravaged state of the seas) reminded me that the dramatic Swanage Pinnacles and arches are just down the road. Having paddled just once last year, this would be a good first paddle to break in the shoulders. Last summer got nixed by a big book job, which was tackled full-on and did in my back for months and months – all compounded by finally catching the Covid (or so it felt).

As beach towels and brollies were getting unfurled, I unrolled my boat and left Swanage Bay (above) at the bottom of the tide. It would carry me north against a light breeze that would flip and get behind me around noon.
But setting off towards Ballard Point (left), the TXL was all over the place, handling like a 1psi vinyl bath toy. Had I forgotten how to paddle straight in the last year? I groped under the stern with the paddle to see if it clanked against the skeg. Either I missed it or it wasn’t there.

Back on the beach, sure enough – no skeg; probably dislodged while putting in. This happened once before, landing on a rocky ledge where the fore and aft of the shallow surf saw the skeg slip its mount. After that I wrapped it in hi-viz tape.
I couldn’t see how it had happened today on a smooth, sandy beach, but I spent the next 40 minutes wading up and down, juggling estimates of longshore drift with onshore breezes, but unsure exactly which of the 20 Swanage groynes I’d set off from. I finally accepted the skeg was MIA: some errant doggie must have snapped it up and rushed it back to its bemused owner. Drat – and I’d paid for 6 hours parking too! I went for a swim anyway, ate my sandwich, then packed up while a beaky seagull dryly observed the lambent folly of human endeavour.

*Look for my Skeg, ye Mighty, and despair!*

Heading back, I recognised a little sandcastle I’d passed on my way down to the shore, all of 2 hours ago. Was it here I put in? I wandered back to the nearby groyne on the off chance, but soon got distracted by the flash of some sunglasses. I waded round the end of the groyne to pick them up and there sat my skeg! Like a lost desert traveller expiring just one dune short of a palm-ringed oasis, my search had been one groyne short. Saved by a thoughtful beachcomber, I grabbed my skeg and left the shades: this show was back on the water ;-)

Don’t lose your skeg
The lack of tension, even once inflated, can dislodge an Anfibio skeg following a small fore and aft movement of the hull pressing on the sea- or riverbed. On a flowing river, skeg-free is not so bad and you might need the clearance anyway, but at sea you definitely want a skeg for good tracking. Here’s one solution.
• Stick something like a fat sharpie under the rear skeg patch to lift the fabric away from the hull; you don’t want to stab your packraft
• Make two incisions which line up with the hole at the back of the skeg
• Feed a reusable cable tie through the slits and leave it in place. The skeg will now be secure

Skeged up, the TXL sliced NE towards Ballards Point like a troupe of dolphins late for the ball. I was sitting on the optional floor inflata-mat, which stiffens the long hull, reducing drag).
Edging towards the Point, I could feel the boat slowing down against the eddy hooking back southwest into the bay (left; LW+3). Passing over the corner some clapotis (below) was jingling about, pushed up by the eddying current.

Once round the corner, with the wind and tide now behind me, I was expecting record speeds. As usual though, with a backwind you lose the ‘wind-in-your-face’ impression of speed, which can be quite dissatisfying. To my right, jet-skiers were thrashing about, making me feel uneasy. Paddling quietly along, it’s hard not to feel intimidated, far less any aquatic fraternity towards these wave-jumping motocrossers. The sooner they all go electric the happier we’ll all be. But either way, I bet they’re a blast to ride!

Up ahead rose the oddly nameless Jurassic fang, seen behind Attenborough at the top of the page. All the other outlying pinnacles hereabouts are flat-topped. When you work out the thin rib of chalk where they got DA to stand to get the shot, you’d hope there was an unseen safety line securely attached to Britain’s most treasured national. As I passed between the fang and the cliff wall, a gust shoved me through, and I saw later the GPS had hit a dizzying 9kph.

Beyond lay the first of the chalk arches which make this paddle so special, and why it got featured on the title page of my IK beginner’s guidebook (below). At the first small arch the wind bounced me back off the high walls, then whooshed me through the calcified portal like a popped cork. On the far side some paddle-boarders out of nearby Studland were taking a break on a tidal ledge.

With the tide about halfway in, I threaded the passable arches around Old Harry’s (above), while other paddle sports enthusiasts milled about at the geological wonder of it all and from the cliffs above, walkers looked down with envy.
Once round the corner and in the lee of Ballard Downs, all that remained was to head west for Studland South Beach and pull the plug.

With a bit of energy to spare and nothing to lose, at one point I put my head down and powered on to see ‘what she’ll do [mister]’. The GPS data log revealed a blip from a steady and sustainable 5kph to a limited-endurance 6kph, which would soon drain the batteries. Six kph must be the maximum hull speed of a TXL on near still and windless water. Better to save such efforts for unwanted offshore headwinds. Even then, looking at the data below, I’m again amazed what a portable raft which you can easily pack up and walk with anywhere will do on the open sea. ISuPs may be loads more popular, but to paraphrase former Met Police commissioner, Robert Mark, ‘I’m convinced packrafts are a major contribution to paddle sport adventures’.

On South Beach oiled-up heliophiles were laid out like seals. It reminded me of a radio doc about boredom I’d caught the previous evening. In an experiment, apparently 70% of males preferred to self-administer a light electric shock rather than sit still in an empty room for 15 minutes. They should give them a sun bed next time, but perhaps I’m missing the point.

I could have walked back the couple of miles over Ballard Downs to Swanage, but what with the time wasted on the skeg search-and-rescue mission, I didn’t want to risk getting back late to the parking before something terrible happened.

So I treated myself to the 20-minute open-top #50 bus ride back to town.

All together now:
We’re all goin‘ on a
Summer holi-day…’

Sigma TXL • bow skeg and knee straps

Leave a reply

Sigma TXL main page
Glues and Repairs

Years ago I remember when the value of fitting packraft rear skegs was debated. Then, the now common longer sterns were introduced by Alpacka and positioned the paddler more centrally which greatly reduced excessive bow yawing. The problem was largely solved.
On a packraft you’d think a skeg under the bow would eliminate the yawing endemic to short, wide rafts while compromising turning agility. In fact, I wonder whether a packraft might yaw nearly as much at the back but you never notice. Like one of those Turkish dervishes, you’re actually pivoting from the middle of the paddle shaft, or perhaps a bit behind, at the centre of mass (left).

Rear skegs certainly improve tracking on IKs; you can manage without, but with a skeg you can paddle harder without constant micro-correctioning. On rivers I’ve found solo packrafts paddle fine without a rear skeg; or they’re too short to demonstrate noticeable improvements. There’s a bit of nodding as you move off which soon settles down with some momentum and a steady cadence. Even my symmetrical Rebel 2K (left; stern identical to bow, not extended) paddled fine down the Wye without a skeg. But when getting pushed around by a swell or on sea lochs (especially when sailing) fitting a skeg was worthwhile.
Either way, rear skegs are a thing now with packrafts even if you don’t have to fit them every time. Certainly on my longer TXL I like to think the stock rear skeg aids coastal paddles; though we found a brief stint with no skeg was only slightly noticeable, paddling into the wind in a sheltered loch (no swell). Anyway, I’ve been curious to see what effect a frontal skeg has, so on buying my TXL I ordered a spare skeg and patch which Anfibio also sell separately for €21 + €6.

Goop no good; Aquasure OK; Helaplast better

Gluing on a skeg patch
As stick-ons go, this is not a mission critical job but you want to line it up dead straight which I now see is better done with the boat inflated. I just used the rear seam, hoping it was along the middle line. Anfibio recommend Helaplast which they can’t post outside of Germany, but which you can buy on ebay.uk (from Germany…) for €7 for 50ml.
There must be something similar in the UK, but the problem is identifying it against something that provenly works. I had some Goop contact adhesive, but whatever their ‘Automotive’ variant is, it did not stick at all. So I decided to try some Aquasure+FD, leaving it to cure for half an hour before sending in the roller. That seems to have worked.

Make sure you don’t glue the middle down!

Knee straps
Part of me likes to think I’ll be using my nippy TXL the way I use my IK: fair weather, open-water sea paddles rarely more than a mile from shore. As this might require sustained periods of paddling I figured some knee straps would help, as they do in my IKs. It’s not so much for hardcore bracing or even rolling, the way they’re used in white water, but just to lock-out the legs so the core is more connected and you get good drive.

Anfibio sent me their latest 5-point thigh straps which I tried and liked on the Revo (left). But to make full use of them would require gluing on up to 8 extra patches (if not ideally the ladder patch; left).

I decided my old Anfibio 3P straps which I’ve used for years in my IK would be OK for my low-tension, flatwater use. They require adding just two pairs of attachment straps. I could have got away with the unused flat patch by the seat, but the direction on tension was off centre and would eventually wear, stretch and maybe break. These small patches are not really designed for such loads and now my Helaplast has arrived, I decided to try it. An old post on the Anfibio blog explains how to use Helaplast:

mark off area on hull
mix hardener 20:1
clean surfaces with solvent
apply a thin layer to both surfaces and wait 30 minutes
apply another thin layer and wait another 10 minutes
Position patch; it won’t adhere properly
Heat with hair dryer to reactivate glue and press down hard with roller. It’s better if the boat is deflated to do this on a hard surface.

The heat reactivation trick was not one I’ve heard of before with glues (except to loosen stuff), but you could see it worked. Where the positioned patch was lamely stuck to the boat, a bit of heat saw it bond down well with some added rolling. You can tell when something looks well glued and this feels like it, though I’m sure glad I didn’t have to do that another six times.

Update
Having paddled about with the straps a bit, they work OK, but the front mounts need to be lower to hook well over the knees without using the cross-link strap to pull each strap inward (not what they were intended for – entrapment hazard!). I did this a few days later. Knee straps also make a good set of handles for moving the boat about like a giant holdall.

Thigh strap attachment points are better off set low at the front.

Short answer: IKs: yes. Packrafts: helps away from white water

Generic, over-tall skeg. Snap-prone but trimable.

A skeg is like a fixed ‘rudder’ under the back of the boat which makes it easier to go straight (track). Only the very cheapest single-skin vinyl IKs don’t have skegs (Grabner, one of the most expensive IKs, is an exception; though it’s an optional add on). If you’re IK doesn’t come with one, it’s easy to glue one on (see below).

Some flat-floored IKS have up to three (imo, a gimmick), and many skegs on Chinese-made IKs are unnecessarily tall (too deep) which makes them snap-prone. Just about all skegs can be easily removed by hand, because in shallow rivers you might want to do so to avoid grounding. You can as easily buy a spare and trim it with a hacksaw.

Gumotex skeg glued to a Grabner Amigo

Original over-sized Gumotex alloy skeg on the left. Later smaller; now tough plastic.

Years ago Gumotex introduced a slip-on, black plastic tracking fin (skeg, above) which was near identical in shape to one I’d had made to replace the old-style oversized alloy skeg (left). A smaller skeg made better clearance and still tracked fine. But metal bends; tough plastic is much better and that’s what all their boats come with now.
I’ve fitted these plastic skegs to older Gumotex IKs and other IKs. The kit is about £25 + glue, and the plastic skeg is pretty much unbreakable. Just make sure you glue the mounting patch on really well; it helps if your boat is made from a matching rubber fabric as the supplied Nitrilon patch or make your own patch from same fabric. But I have glued PVC to rubber successfully – use good two-part glue. The pictures below help you see where to position a skeg.

On shore a skeg is a pain with a loaded boat

Skeg: underneath and at the back

Gluing a Gumotex fin to a Grabner (which come with no skegs)

I fitted the Gumotex plastic skeg to my Grabner Amigo IK (above) and at sea used it all the time. But on the shallow River Spey (below) this boat didn’t handle at all well without a skeg, possibly because the tailwind pushed the kicked-up stern around. It was really quite annoying because a few years earlier my broadly similar Sunny managed the Spey just fine without a skeg, so skeg-free tracking clearly varies from boat to boat.

Paddling without a skeg
If you’re an experienced paddler you’ll have acquired the knack of going straight without a skeg – handy for paddling shallow rivers where the skeg would ground. A little more paddling finesse and constant small corrections are required, especially if powering on.
It’s good to learn this technique before you need to: fix your eyes on a tree or marker on a distant bank and paddle as gently as you like towards it, not looking away and keeping the nose of the boat in line with the marker. By using very light strokes you’ll see it can be done if it’s not too windy when again, a skeg helps with tracking (going straight).

Gumo Solar with no skeg

I even found I could paddle a ten-foot Solar 300 (above) without a skeg. Once you know you can go straight without a skeg, it’s just a matter of adopting the same finesse but with a bit more power. Only when you attempt the speeds of a Viking longship will bow deflection or yawing get too much because to paddle faster and still go straight you need a skeg. Out at sea or on busier rivers, I always use a skeg.

IK&P Tip: drill a small hole in your plastic skeg and attach a ring or zip tie directly to you boat. It’s annoying to turn up and find you misplaced your skeg.

I’ve often thought a hinged retractable skeg would be a good idea: it would pivot backwards when dragging in shallows, then drop back down when there’s enough depth. It seems SUPs need skegs and in the US, FrogFish have made such a thing for boards, but you hear the spring can be a weak point.
If your kayak has a rudder mount (or you can make one), another way of doing it is fitting a swing-down skeg similar to kayak rudders. It works the same way as a rudder with a looped cord swinging the skeg up over the stern, or down into the water. The pivot skeg shown top right is made by Advanced Elements for their AirFusion IK and costs about $/£80. Or have a look here.

Packrafts

On shorter, wider, slower solo packrafts the consensus used to be that skegs made little difference. Especially when unloaded and with a full-weight paddler, the bow yaws merrily left to right as your paddling pivots the boat from the back. Or so I used to think until I tried the skeg on my Rebel 2K. Up to then I’d been ambivalent about them – using the same boat fully loaded a few weeks earlier on a fast flowing river, yawing had not been an issue. But unloaded (and with my generous 95kg of ballast) yawing was notably reduced with a skeg. Speed however, was the same or was too small to measure.

If you think about it, a packraft actually pivots from a point around the middle of your swinging paddle, not from the stern, as it feels from the seat. The centre of mass behind the pivot point does make an unladen bow yaw more, but the stern will yaw too; just less and unnoticed.

Longer stern puts you more in the middle of the boat, like a kayak

One reason some packrafts may manage without a skeg is that way back in 2011 Alpacka invented the ingenious extended stern (right). It helped limit yawing much like a skeg, and effectively positioned the paddler more centrally, like a kayak, while also adding trim.
This idea has been widely copied by just about everyone since and it definitely works, compared to the original dumpy Alpackas. But as mentioned, once there’s a good load over the bow, yawing is reduced in any packraft. Anfibio sell a detachable shallow skeg and glue-on patch for €21. My Rebel 2K came with a skeg and I must admit I use it most of the time now. But it does not have a fully extended stern like the Alpacka above right. Then again, my longer Nomad tracked great without the skeg.

Skeg on an Anfibio 2K. Reduces yawing

Frontal skeg?
Now I have a longer 2.8-m Anfibio Sigma TXL and I was curious to see if adding a frontal skeg would make a difference. Seated centrally or two-up, this boat does not yaw from the boat like an unloaded solo packraft, but it does wander a bit (track poorly), especially with the inflated floor pad). I decided a front skeg did not help much, though it might improve sailing.
