Back in the sunny Summer Isles

Here we are back in the Summer Isles for the duration. Temptingly calm and sparkly out there right now, and we’re told it’s been fabulous weather these last few weeks.
On his blog, this chap reported 28°C a couple of weeks ago near Lochinver just north of here. Check out his pics, because through all the windy days you get up here, seemingly lit by a 25-watt bulb, when it’s fine and calm and bright you wouldn’t want to be anywhere else, in or out of a boat.
As you may know the south of the UK is getting a hammering – storms in Cornwall, floods in Wales then Sussex, and the wettest April plus coldest May since EMI set up shop in a Kilburn garage. On the drive in to the Coigach, streams like the Osgaig looked distinctly boney, the adjacent lochs failed to join up like they used to, revealing instead hitherto unseen sandbars, and the moors are the colour of bark not rotting lettuce – terrible news for midge lovers. There was even a bushfire on Tanera Mor island (left).

And as you’ll read on here soon, on his second attempt, French aventure-gonflateur Gael A successfully completed Stage Two of his run up the Scottish Sea Kayak Trail, from Skye to Ullapool via the Summer Isles in his Incept K40 (the same one featured here) – and he did so it seems without any dramas.
 Left, the commitment-requiring Rubha Reid headland which he didn’t even reach in 2011, and right, Tanera Mor ablaze in sunshine, as opposed to burning peat.
It seems this prolonged spell of reversed weather in the UK could be down to the jet stream which, according to a BBC report, has flipped and is talking a southern course along the England Channel, instead of straight above here on its way to Murmansk (right). As a consequence (and as HMtQ found last week) that translates to a low pressure  over England which I do believe results in the top end of that low drawing in hot and dry continental air westwards across Scotland, not the usual southwesterly Atlantic mush that’s fit only for wind farms. Can’t be at all sure I’ve interpreted that correctly, but Scotland’s been getting it good for weeks, so here’s to the jet stream continuing to water the shires of England while we live it up here in the far northwest.
While schroling through the backposts at …kayak.fr I spotted this semi-interesting slideshow of the history of Zodiac dinghies. Well over a century old they are, and they even made a super-wide IK just before WWII. What was interesting is that they didn’t give a mention to our old friend Bombard’s Atlantic crossing in the early 50s, something he managed while relying almost entirely on seafood, seawater and rainwater. Instead, golden boy Jacques Cousteau gets a shot with what I believe is a huge, 20-metre hyper-Zodiac causing a traffic jam en ville. It dwarfs the 8-metre Grand Canyon support rafts we saw at Lees Ferry the other week. Apparently the hyper-Z took so much air to inflate it that locally, asphyxiated birds would drop out of the sky. Here’s another still of a sleeping croc with its paws affectionately draped over the Zodiac which probably finished him off.
I read also that at one stage Zodiac Marine bought out (or perhaps produced?) the execrable Sea Hawk slackrafts with which a mate and I paddled the Chassezac river last year. It’s no exaggeration to say his survived undamaged for about five minutes.
Back to the Isles, I’m told that sea kayaking has really kicked off so far this year, with weekenders regularly putting in at the new Port Beag campsite, right opposite Isle Ristol.
Meanwhile, my flaccid K40 is sunning itself on the lawn, easing out its creases after being rolled up and shoved in a dark cupboard since its not-so-successful Ningaloo outing in Australia last September. Amazingly it still looks pretty fresh and hasn’t been eaten alive by microbes. Time soon to pump it up, see if it holds air, and take it out for a spin.

Preparing the Slackraft for Escalante

In a month I’m back in northern Arizona for an Expo and afterwards hope to have another crack at the Escalante River (left) in southern Utah. I had a good look around last year at both put-in and take-outs, doing everything short of actually paddling the river. This time round it’ll be a month later so hopefully warmer and if the river’s too shallow (they say there’s been little snow this winter), that suits me fine. We proved on the Fitzroy last September that wading through the shallows pulling your packraft is most agreeable and good leg exercise.
I’m also pleased to say I’ve persuaded the Mrs to come along, and not only that but to come with in the expedition-untested Sevy Slackraft I made over the winter by cutting the outer hull chamber off a cheap PVC pool toy to make a slimmer cheap PVC pool toy resembling something you might enjoy paddling. Seeing as she’s half my weight it ought not sink on her as it did for me, and I’m happy to carry the food and camping load in the bombproof Yak.
There is a chance of course that the Slackboat will catch a buried stick and rupture as Jeff’s did a few times on the Fitzroy. Having learned from that experience, to give the Slacker’s floor a chance I’ve glued on a sheet of ‘ballistic nylon’ I had left over for the same floor protection purpose on my first Alpacka. Best not to read too much into ‘ballistic’, but as I happened to have some going spare it’ll be better than a cheap PVC tarp or cheap tent nylon fabric.
First I applied a few runs of double-sided carpet tape to save on glue, though this tape works out at nearly £1 a metre. I then laddled on some EvoStik and finished the whole job off with a seamless montage of duct tape. See pics below. The finished boat weighs less than 2.1kg (4.6lbs) and packs up more compactly than the Yak. Rather worryingly, as I deflated and then sucked the last of the air out to make it roll up compactly, the inside air was heavily laden with glue vapour. I’m expecting a headache or a high soon. The EvoStik tin did say not for use with soft vinyl as well as other materials, but as the boat held its air well for over 24 hours after gluing, the glue can’t be said to have dissolved the boat – maybe it just permeates. In fact it doesn’t – first go out on the sea it all came apart, so maybe ‘Nevo’-Stik is a better name. I should have used the same glue I did on the Alpacka, but that costs nearly as much as the Sev.
So, with a bit of care and luck, my re-socked paddling pool ought to last the three-day outing down the Escalante. And if not we can both squeeze into my Alpacka Yak, making sure we dispose of the shreaded remains of the Sevy in a responsible manner.
Assuming the plan rolls out [it didnt’], the river runs fine and the weather is good, they’ll be news on that caper at the end of May.

Packrafts; alternatives to Alpacka

Updated summer 2018. Did you miss the general packraft intro?

supai22For sporty rivers, inshore use and touring, Alpacka’s comprehensive and innovative range lead the field for many years, but several alternatives are now on the market. Some copy the original Alpackas closely, some are ‘crossrafts‘ suited only to calm rivers, short crossings and flatwater. They prioritise ultra light weight over durability which can be a gamble outside of shallow, tropical lagoons. As in Alpacka’s range, others are designed to carry heavier loads, be as light as possible or for all-out white water
slackieslackersDon’t forget that at any waterside holiday resort you can always buy cheap PVC ‘slackraft’ pool toys that are OK while they last. Slackrafts get their own page on IK&P and are a great way of investigating the packrafting experience before you splash out on the real thing.

pakGTbannerMost of the boats described below I’ve only seen and evaluated from pictures, but in 2015 we tested four packrafts from MRS, Aire, Nortik and Supai alongside my 2014 Alpacka Yak. To read more about our actual observations and conclusions (as opposed to this page’s web speculation) click this or the banner on the left.S1 - 44

A word about denier – a unit of measurement used to describe the weight (not the thickness) of a material. It is calculated on the mass in grams of a single 9000m strand using one 9000-m long strand of silk as a reference for one denier). It’s a mistake to think a fabric made from 210D nylon will be three times thicker and three times stronger than 70D. The thread or yarn used ought to weigh three times more so will be stronger and more resistant to tearing, but not as a factor of the D-rating.

What have been dubbed crossrafts are sub-category of packrafts – very light rafts or ‘trail boats’ made from nylon or polyester with a coating onside (like your tent or backpack) as opposed to much more durable exterior coating found on TPU; the shiny stuff of a normal packraft.
They are best suited to crossing calm bodies of water rather than paddling alfa - 4along them, far less tackling white water, though this doesn’t seem to stop people trying. The low prices and light fabric enables weights of well under a kilo, making the link between slackrafts and packrafts. But because of the fabric you do lose out on durability, performance and response from the stiffer TPU hulls found on packrafts like an Alpha XC (left) which still weighs much less than 2kg and gives you more peace of mind when travelling along in remote locales.

Supai Flatwater Canyon II
supai-packraft-dimensionsAs the name suggests, the 670g Supai Flatwater II is an ultra-light trail boat suited to crossing small lochs, canyoneering or following calm rivers. With its narrowed and tapered bow, it resembles the much admired Sevylor Trail Boat – the Lost Prince of Slackrafts – and at the time appeared to be a more sophisticated and notably lighter take on the FlytePacker (below). The Supai’s dimensions as measured by me added up to 92cm wide, 157cm long and 106cm inside. We tried one – read about it here. A couple of years later we also tried the fatter Matkat version too.

NRS Packraft nrspackraft
NRS’ tough MaverIK introduced me to inflatable kayaking in Idaho all those years ago – I nearly bought one right on the spot. A while back they added a packraft to their line up. At 203cm long and 91cm wide (33cm x 142cm inside), the NRS Packraft is a roomy boat weighing 3.35kg with the removable floor, or 5.6lbs / 2.54kg without, so it’s too heavy to be a true crossraft.
Like a Supai it’s made from PU-coated nylon: 70D in the tubes and a floor in 210D. There’s a seat pad too to get your bum higher than your feet, necessary for a comfortable and efficient paddling posture. Like the discontinued Feathercraft BayLee (bottom of the page), the NRS has two chambers with simple one-way Boston valves as found on £20 slackrafts and many packrafts now. An inflation bag is an extra $30.
But check out the NRS website reviews – not such glowing reports with regards to durability. It does seem a rather half-backed effort which is a shame as NRS IKs and rafts are famously tough. This guy took his down a rapid-strewn river in Oregon. You may want to skim down to the last few paragraphs. And this guy in the UK bought one in 2015 for more recreational paddling to which the NRS Packraft may be better suited.

Flyweight Designs
FlytePacker-1Supply comes and goes and perhaps may have gone for good, but Flyweight Designs produce an ultra-basic 200-D coated nylon FlytePacker (right) for about $315.
Stats are 1270g, 107cm wide and 178cm long, with a claimed payload of 140kg.
 This version is less wide and a bit longer than the original FlytePacker and so compares with the Supai Matkat we tested in 2015.
FWDFWD’s other boat is the more conventionally proportioned CrossFlyte (right). FWD use the inner tube plus outer skin approach, both from 70D coated nylon. An inflatable floor may fit in there too. Weight is 1590g and it’s 185cm long, 101-104cm wide – nothing special when you compare it to Anfibio’s TPU Alpha XC which I bet is more robust. There are four attachment points on the bow as well as tape rowlocks on the sides.
Looks like both boats use Boston valves, a simple and cheap way of getting more than lung pressure in there and still works with an air bag. Even then, I have a feeling these inexpensive, thin-skinned rafts make for very light but saggy and unresponsive boats – in other words a crossraft to merely get you to the other side.

rutaRuta Locura make a licensed 75D version of the LWD that Klymit used to make (LWD stands for ugly duckling, btw). It weighs under 800 grams (left) and so puts it between the Supais. Me, I’d skip a cup of coffee and take on the extra few hundred grams or just save up and again, get something like an Alpha XC, a ‘thin-tubed’ Anfibio which weighs 1800g all in.
LWDDODavid O from Oregon was last seen persevering with his Klymit, and after trying to make his own packraft from bin bags (right) has set about adapting his Klymit LWD for heavy-duty ops. More here or in the vid below which contains scenes some viewers may find unnerving.

Advanced Elements Packlite
aepacklitePackraft attempts to meet kayak with a splash of slackraft graphics: behold the Advanced Elements Packlite ‘splackraft’Fabric is a similar ripstop PU-coated polyester as used on the Supai (denier unknown). What they call ‘military valves’ (i.e.: IK valves as opposed to Boston valves) are used on the two-chamber hull so the thing ought to pump up firm. That might be the problem as they sem to burst.
The I-beam floor is inflated with a regular twist lock valves to avoid over-pressurisation. The deck net becomes a carry bag and there are a few D-rings, plus the AE signature moulded rubber handle. You won’t get far without that.
Price is $299 and it has to be said this looks like a great combination of interior space, shape and weight, and claims a realistic 250lbs/113kg payload, but you can’t help equating those naff ‘world map’ graphics with a crap pool toy. Tubes look a bit slim and low and it needs a bulky pump, but overdo it and you risk leaks or outright bursts. The video below features an eminently svelte paddler; you wonder if it would sprint so briskly with a bloater like me in it. As is often the case – the genuine reviews on amazon tell the full story. Caveat emptor on this one.

alfa - 83fibsAnfibio
The Anfibio Packraft Store in Germany offers many brands of packrafts and collaborates and sells MRS from China (we tried the MRS Microraft). Lately the Store has co-designed their own brand of Anfibio packrafts which are among the lightest in anfisigmatheir class. We tried the Alpha XC (above left). From just €470 + seat, a great deal for a light paddler.
The range includes the Delta MX and Sigma TX, a compact double (right) which is 1.6m long inside, weighs just over 2kg, is rated to carry 220kg and goes from €680 plus seats.

With a small range of models from lightweight to white water, as well as tandems (two models are sold in Europe by Packrafting Store), the distinctively angular shape of US-made Kokopelli packrafts sets them apart. Another distinction is the use of a Leafield valve you’d find on a IK or whitewater raft which inflate to higher pressures with kokoleafpumps. And yet Kokopelli packrafts still inflate with regular air bags and then top off with a detachable mouth tube. It seems like overkill. See this video where they say you can inflate up to 2psi. A K-Pump will easily do that but it’s probably not possible by lung unless you’re 1970s muscleman Franco Columbo who managed to blow up and burst a hot water bottle.
Certainly for paddling efficiency you want as firm a boat as possible, especially once a packraft gets beyond a certain length. But over-inflate it (or leave it in the hot sun) and it may well rupture a seam. (I did that with an IK once.). So lung pressure is safest.
kokonirvThe Kokopelli range includes the Nirvana white water boat (left) which comes as a self-bailer or with a deck. Decked packrafts are two-a-penny now but self-bailing is a more unusual solution to white water packrafting, more common on big white water rafts where you sit on thwarts high above the wet floor.
In a self-bailing packraft or kayak a thick inflated floor pad is needed (or just big fat seats) to get you above the water that will always be present kokoflooraround the floor. Holes round the edges (small picture right, and like the discontinued Baylee, below) see excess water flow out. What pours in over the sides flows right out the draining holes until the water level reaches equilibrium; the boat cannot get swamped.



I know from IKs that self-bailing can mean a higher centre of gravity due to the thick floor or seat which can lead to instability, but just as with full-size rafts, with wider, flat-bottomed packrafts that’s probably much less of an issue. Depending on how fast it drains, for whitewater I think I’d prefer a bailing packraft to a deck and skirt, but that’s partly why I also prefer open IKs.
twainKokopelli’s other main boat is the more sedate and roomy tandem Twain, over 3 metres long weighing nearly 7kg with all the bits including a front seat with a proper backrest, but with 225cm or well over 7 feet of length inside. Two tall adults and gear will not be cramped.
Unusually again, the Twain features the Leafield valve, an inflatable floor but also a removable skeg at the back like an IK. You’d think a long boat like this would not have tracking issues any worse than regular sized packrafts.
A packraft like this, as long as a kayak but running on lung-pressure psi, will need all the help it can get to be rigid and not paddle like a soggy Sevylor. Blow it up as hard as you can but I’m not sure a regular low-psi floor will add that much. It’s known that the best packrafts can take much more pressure than we can fill them with – up to 6-8 psi I’ve been told before something goes. Are we already knocking on the door of longer packrafts with high-pressure drop-stitch floors? A detailed Twain review here.

KraftOver in Australia or New pakraZealand? Then look up PacKraft who make their own boats to order and also sell Kokopelli.

sputnixSputnik packrafts
Latest on the scene are Sputnik sputlogpackrafts found on ebay from under £600. Looks like an Austrian design or brand that’s made in Russia by TimeTrial.
There will be a certain kudos in having enigmatic Cyrillic on your boat but, not unlike the German-designed/Russian made Nortiks (maybe even the same factory?), from 3.7kg for the Sputnik 1, these are relatively heavy boats using tough 420-D sputnikpkkhulls with heavy 650g/m2 PVC floors when most others use 210D hulls and 420 TPU floors. Remember: heavy does not always equal sput3robust and durable, as with MTBs it can just mean cheaper.
Sputnik 1 numbers are: 250cm x 100cm, 30cm tubes, a very generous if not perhaps baggy 40cm width and ballpark 125 inner length with a load capacity 150kg. The range goes right up to a Sputnik 3 (left) which is a true double at no less than 3.5m long (2.25m inside) with a quarter-ton payload weighing in from 5 kilos.
It says they come with a basic inflation bag valve (like old Alpackas) or the Boston-like one-way valve which you can pump up to a little beyond lung power (a better choice IMO, especially for the longer tandem), as well optional fitted kayak decks for white watering.

Feathercraft Baylee River Runner: Feathercraft have stopped making boats
FCBL1The naming is a bit confusing but Canadian portable kayak makers Feathercraft produce a couple of packrafts under the BayLee River Runner label. Several years ago Alpackas were actually made under contract at the FC factory in BC, so something like this was bound to happen as packrafting caught on.
Their one-person BayLee 1 River Runner is packraft that comes as a standard open boat (above right; 2.95kg; $1050); with a spray skirt (left; 3.4kg) or with a self-bailing floor (4.54kg – $1400 – see below).
As far as I can work out they’re all based on a 2m x 94cm hull with big 30cm tubes. There are larger self-bailing BayLee/River Runners called the Bolder and Beast, but these models weigh up to 9kg so can’t really be considered packrafts. All of them come with optional skegs which are probably more useful for rowing the larger omnidirectional versions.
ebayleefcinflaterAll BayLees are made with two air chambers, left and right, and each chamber is RF welded and then glued and taped together so there are only visible seams at each end giving a much smoother look and less chance of bad seams turning leaky. They also feature chunky, one-way Halkey Roberts rafting valves on each chamber, as well as twist lock top-off valves. Rafting valves may seem like overkill but do mean that with a pump rather than an airbag you can get a good, firm pressure in there (and which does make the twist-locks redundant). Indeed the self bailing BayLee (below) does come with a pump.
The self-bailing BayLee (left and right) drains fast, just like big, white water rafts. Although this adds about a kilo over the skirt version (based on the specs above; FC claim less), it has a higher seat making the boat marginally less stable. Note the rudimentary leg brace on the left, too – presumably it unclips easily. For pure white water packrafting this self-bailing system is probably better than the Feathercraft’s basic spray deck. Alpacka’s Alpackalypse which came out a couple of years later has a more sophisticated, creek boat-like solution to the interminable packraft deck problem.

pakghostAlpacka Ghost Withdrawn
For 2015, Alpacka make no bones about the fact that the new Ghost crossraft is not as durable as their regular boats. It’s small too – about six feet long or the size of their Scout, and 10-inch tubes means not as buoyant. But you’d hope the 20D TPU fabric might be tougher than PU-coated nylon. Their 2000-gram Curiyak (see below) in the same fabric might make an interesting crossraft for the larger person with gear
