Leaking pressure release valve (PRV; Gumotex)

PRV maintenance by Marcin

Durness beach

The other day we paddled the Seawave off Durness beach where the surf was bigger than I’m used to. Hitting a breaking wave as we paddled out didn’t help; the swamped boat needed tipping out at the next beach. It was a bit too offshore windy to roam, but it was still a thrill to be paddling on the very top of Britain, just 2175 miles from the North Pole (about the same distance south to the Canaries).
After the paddle I took care to dry, wipe down and roll the boat up on a sand-free rock bench, but lacking a hose back at the house, I had to rinse one bucket at time – not ideal. When I pumped up, the floor soon went flat: sand was in the seal of the floor’s PRV (what’s a PRV). It’s a thing that happens but in nearly 20 years of Gumotexing it’s never happened to me. Today was my day.

Seawave PRV

The design of the valve means that if the boat swamps in the surf, water laden with grit can enter via the six vents and pool in the valve body right above the seal. The next time it purges, sand grains can slip down onto the soft rubber seal surface and stay there, letting air leak out.
Because the chances of this are high, with a leaking floor PRVs are the usual culprit, not the nearby inflation valve with its sealed valve cap, or less still, a puncture. But don’t rule either out (the cleaning procedure for an inflation valve will be the same).

Fixing a PRV
Much of what follows is my take on Polishman Marcin S’s translated post linked above. It’s not how I actually did it, it’s how I would do it next time after quite a lot of trial, error and better ideas or procedures though up along the way.

Before disassembly, first try giving the PRV a darn good blow-through by pumping like billy-o and letting it purge. It will help to prise off the vent cap with a small flat screwdriver so grains blow away, not bounce back in. Pump up and see what happens. Chances are it won’t work.

Next I suggest putting the boat on a slope (to save water and weight) and flood the stern to establish the pace of the leak from the PRV. You will do it again at the end to see if there is any change. By dragging the boat around 180°, you can let the water slosh down to the bow while you remove the PRV at the stern at the high end.

Don’t plug in a manometer to try monitor the leak over a period of time; it cost me a few hours and a disassembly or two before the flooding idea proved my manometer was leaking from the base faster than the PRV. As we know, pressure gauges are plugged in briefly to get a reading, then as quickly removed. To test for a leak, water is best.

You now know for sure the PRV is leaking so will have to remove and clean it. Flicking off the vent cap exposes the valve body’s six splines. Fit your Gumotex valve tool (or eBay clones from £6) and unscrew the PRV. As Marcin says: the plastic one will do; you don’t need the expensive metal one Gumotex also sell. Expect the PRV to be very tight. Marcin pre-lubed his, I didn’t but it undid easily enough. My boat is less than a year old.

It’s easier to start unscrewing the PRV with the boat fully inflated, but separate the two parts of the valve only once fully deflated so there’s less chance of the backing nut inside the hull rolling away out of reach. Same with the loose o-ring on the valve body base; don’t let it drop into the abyss.

With the PRV in hand, you can see how it works: a spring-loaded valve opens upward when pressure from within reaches a pre-set level – on a Seawave supposedly 0.25 bar or 3.5 psi (but it might close as low as 0.20). As pressure drops it seals shut. At this point you might try rinsing under a tap while pushing the valve open, but you’re going to have to disassemble it anyway to check the state of the seal.

Set the o-ring aside and unscrew the 6mm locknut on the valve stem. Press on the sprung valve from the other side to stop it spinning as you unscrew the nut. But before you do this, count the number of threads or take a photo (above), as the position of the nut regulates the purge pressure; the more you screw down the nut the higher the purge pressure. I notice Marcin’s nut on his Solar was much less screwed in than mine (lower purge pressure). (At one point I tried screwing in my nut an extra turn to improve sealing, but it didn’t seem to make much difference; still closing around 0.2. Maybe a few more turns are needed, but of course you don’t want to go too far and compromise the floor.

Left: pliers to undo the nut; magnifying glass and torch to closely inspect the rubber seal. Right: the disassembled PRV. From top left: valve body, o-ring, valve stem with rubber seal, spring, spring cross-washer, 6mm lock nut.

Ooo-er, quite a lot of fine Durness beach on there.

I chose to clean the rubber seal with an ear stick and toluene solvent. (I tried, but decided not to remove the rubber seal from the stem). After carefully wiping off the grains on, around and under the seal, I dipped the whole thing in the toluene bottle cap (not too long as toluene is strong stuff on plastic; it dissolved the orange marker dot). Don’t forget to inspect and wipe the inside of the plastic valve body too.

A lovely, clean PRV seal. Reassemble and carefully screw down the metal nut onto the soft plastic valve stem to where it was – or what you prefer.

Marcin suggests sticking some sponge under the vent cap to catch grains in future. Sounds like a good idea. These are easily removed/rinsed/dried or replaced by flipping off the vent cap.

A quick Hail Mary to Saint Columba and you’re now ready to refit the valve. You shouldn’t need any lube other than a bit of water for things to reassemble smoothly, though I decided to lube the o-ring with some TiZip silicon grease.
I found as you start screwing in by hand it feels like it’s cross threading. It isn’t: the edge of the fabric is getting caught in the thread. Back up and jiggle the valve body and loose fabric around to make sure the body has slotted and centred its flange into the fabric hole.
Pump back up, tighten the PRV down some more, but probably don’t clip on the vent cap just yet as you may be going back to square one, as I did (partly because the fitted manometer was leading me astray).

Now flip the stern back downhill and let the water slosh back over the Seawave’s valves. I found the PRV purged for about a minute, then abruptly stopped with an odd underwater squawk … but carried on leaking slowly. Another removal and check and refit and there’s still a very slow leak – a 2mm bubble every 2-3 seconds, but with the floor now lying in the warm afternoon sunshine, that may be normal purging. I decide it’s as fixed as it can be. A few hours later, all was normal again and we are all much the wiser.

Moral of the story: if you think sand-laden seawater may have pooled in your PRV (most likely from crashing beach surf, not normal, deep-water paddle-splash), back on shore flip the vent cap off and rinse the PRV cavity with fresh water, ideally flipping the boat upside down, so any grains flush out.

Hybrid (DS Floor) Inflatable Kayaks
Aquaglide Chelan 155 preview
Tested: Kokopelli Moki II

Sea Eagle’s Fast Track 465 (4.65m) is a high-end PVC IK has been around for several years, one of the earliest ‘hybrid’ IKs combining a removable dropstitch (DS) floor and conventional side tubes. It sits alongside their dumpy, all-tube SE cheapies, more whitewatery Explorers, and the all-DS, fixed-floor Razorlites. They even make a full-DS canoe.
From the side the 465FT is a sleek looking IK with slender 24cm side tubes and the distinctive frontal keel under the bow to keep it on track (and which Gumotex have vaguely copied on the Rush models). Quoted weights vary as usual: from 17kg to a ‘hull weight’ of 20kg on the official US website. For a 15.25-foot PVC IK, 44lbs sounds about right.

Sea Eagles only sell these boats in ready-to-paddle packages which include a paddle/s and a pump as well as the usual wrap-around carry bag and repair kit. They start at $1600 or £1299, though in the US are regularly discounted by nearly 30%. When you read scathing ‘reviews’ of otherwise perfectly good IKs panned for not coming with a pump or paddles (even if that was clear at purchase), you can see why SE do this. Just don’t expect a stiff and light paddle.
Upgrades include seats with proper backrests, as well as better paddles, three-seat combos and even rowing and motor rigs. And one thing that sets SE apart is the phenomenal 180-day return period and three-year warranty – at least for US customers.

Though you’ll struggle to see any evidence of this, the DS floor is removable, so it should be easy to clean and dry the boat. Assuming the floor comes out easily, the hull still has somewhat redundant closeable floor drains. Some outlets claim these to be self-bailing ports. There’s a big difference between the two: the former helps drain inaccessible cavities to help dry the boat without removing the floor; the latter allows waves that pour over the sides to drain away via holes in the floor – ideal for whitewater or surf. Such boats need thick floors to sit you high above the drain ports so the kayak doesn’t have water sloshing across the floor and soaking your butt. The 465 (and similar Aquaglide Chelan) doesn’t have a thick floor, though if you’re light you can give it a go. As it is, any 15-foot IK will be a handful in whitewater or surf conditions.

Oddly, the 2014 manual still online suggests you put the same 3.2 psi (0.2 bar) in the DS floor as the tubeless side tubes. Later models have ‘max 8-10 psi labels at the valves, but there is no way you’ll reach that pressure with the archaic foot pump supplied in some base packages. Then again, the couple in the video below inflated their 465 by foot pump. They represent perhaps the recreational core of SE’s customers: prepared to spend four figures but not that bothered about performance or equipment.

One thing that seems to be missing from online images are footrests. For all but the most undemanding recreational paddlers (which may be most of SE owners) a solid footrest to brace off makes a huge difference to paddling efficiency, while also stopping you sliding down the seat. It can have benefits to stability too, although at 91cm wide (36″) that won’t be a problem on the FT as some might find with the FDS Razorlites. Some D-rings could easily be glued on, but for what you pay, it’s odd to not see them included. They’re not even an accessory part. the drainpipe/strap idea I use on my IKs would work fine here.

What they call Deluxe seats are comfy looking vinyl blobs which sit you 5 inches up and clip to the hull sides (as well as the seat base). But because the backs are inflated (via Boston valves), they’ll have little support to lean on because low-psi inflatable backrests tend to crumple under pressure. Non-inflatable foam-board ‘tall back’ seats (found on most other Chinese-made IKs) are supplied in pricier packages will have better back support, except the base is thinner. A slab of foam underneath will see to that, but without footrests you may not notice the benefits.

The innovative Needleknife frontal keel is inflated via a raft valve accessed by a hole in the front floor. Flat, DS-floored boats need some help here, and it does appear to greatly improve tracking, especially while not adversely affecting turning. If that’s the case you do wonder if a long, low slip-on plastic skeg, or just a keel strake as of the Chelan 155, might not work as well with less assembly complication. Perhaps the Needleknife’s softer profile works better, especially in sidewinds where the keel (and low sides) is said to deflect the boat less. There is a large slip-on skeg which is now more swept back, but could still be a bit on the long side. Luckily it’s easily replaced or shortened, but the boat will need some sort of skeg to track well.

Coastal Packrafting

Rebel 2K main page

Around here the inshore sea paddling is exceptional, even if packrafting the inland lochs is also pretty good. Having done most of the latter routes, I thought I might try some coastal packrafting.
Garvie Bay arcing west to Achnahaird Bay looked like a good one and happens to parallel probably the best walk on the peninsula which we’ve done many times. That route could be a 20-km combination of cycling, walking and paddling, but as it was the last calm evening for a while, we thought we’d go out together in the kayak and I’d try the packraft on the way back. That way everyone got to play.

A light NW breeze blew onshore as we cut across Achnahaird Bay like a blue fin tuna. The approach of HW meant we slipped through the submerged skerries of Rubha Beag and into the crab’s claw inlet of Camas a Bhothain (Bothy Bay). This seemed a good spot to deploy the packraft with the aid of my exciting new gadget, a mini electric pump. I unrolled the boat over the water and let the pump buzz away for a couple of minutes, topped off with the hand pump, then clambered aboard.

Paddling away, I realised this was the first time I’ve paddled my Rebel 2K unloaded and I was a bit shocked by the bow yawing. Now fully back-heavy, one good swipe of the paddle and it could flip a 180°, just like my old 2010 Alpacka Llama.

Ah, but in my haste to launch the lifeboat I’d forgotten to fit the also-untried skeg which comes standard on the 2K. I waddled over towards Rubha a Choin beach and slipped it on easily, while the Mrs transferred to the Seawave’s front seat.

I’ve been ambivalent about the value of a skeg on a packraft, but now back on the water the yawing was notably reduced. 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.

On the Wye my 2K was fully loaded with the centre of mass moved forward and which minimised any yawing, even without a skeg. (With a heavy load over the bow a reduction in yawing is well known with packrafts). Now unloaded and with the bow riding high, swish-swosh yawing was exacerbated, but is actually happening at both ends of the boat. So any type of fin or extension of the stern (like the post-2011 Alpackas – right – and all subsequent copies) will constrain this, while not affecting steering. So, bottom line: skegs work on a packraft and are easy to retro-fit.

All the remains is a packraft’s agonisingly slow speed. These are not boats made to enjoy the sensation of flatwater paddling; they are boats to enjoy getting to out-of-the-way places easily. Any type of disturbance to progress, be it wind or current, may slow you to a stop, or worse. Something like the longer Nomad S1 I had would be better for this while still being packable. Still, in these ideal conditions it’s nice to float along observing the coastal features.

Paddling back down the east side of Achnahaird Bay, a back-breeze made progress feel achingly slow. Lately, I’ve come to value metres per second (m/s) as a metric of wind or paddling speeds. Something moving past you (or vice versa) at three metres per second is easy to visualise, though I suppose we can all visualise a 3mph walking pace, too. It’s what YR uses and is easily converted to ‘double + 10%’ for miles per hour (so 5 m/s = 11.18 mph). Or just double it and you nearly have knots (5 m/s = 9.8 kn), for what that’s worth. Crawling past the rocky coast it looked like I was doing 1 m/s at times. We had a race: diminutive Mrs in a big, long kayak; me in the packraft. Within ten seconds the Seawave streamed away while Bunter frothed up the water like a cappuccino machine.

Oh well, you’re as fast as you are. Like cycling in Tajikistan rather than Kazakhstan, for the best experience match your routes with your mobility and conditions. Next calm day I’ll do the full Garvie loop.

Review
An electric pump to save a couple of minutes’ packraft air-bagging? Do me a favour! That’s what I think when applied to bulkier IKs where a two-way barrel pump is fast and easy. But factor in cost, weight, size, USB rechargeability plus supplementary uses and, for a packraft, FlextailGear’s range of pumps (above) is worth a punt.
Air-bagging is a clever idea to inflate a typical packraft, but on some days it’s not the most intuitive of actions, perched on seaweed covered boulders. Once a day is fine, but on a trip where you’re airing up and down a few times a day, the effortlessness of the Max Pump is welcome. A good case to point was my paddle on the Wye where accessing my Rebel 2K’s internal storage pockets to get to the camping gear each night meant re-inflating the boat every morning. The Flex pump would have made this less tiresome. Another example is getting back from a tiring sea paddle and wanting to reinflate the boat to rinse and dry properly. Plug in the Flexy and get on with other after-paddle chores.

Max Pump adapters but none fitted a Boston valve’s two ports just right
Actually the grey rubber nozzle (right) will push and seal into the main threaded port, and with my second Max Pump Plus, there was a hard plastic nozzle to fit a Boston’s mushroom valve (middle) too.
But to reduce loose bits, I made a 2:1 adapter (left) to fit both ports, using tape to make a good seal.

Out of the box
With Max Pump I got the pump, four nozzles, a short USB-A lead and a small bag. While one nozzle loosely fitted a Boston valve’s threaded airbag port / dump valve, nothing fitted the one-way valve body. You’d think with Boston valves so common on Chinese-made slackrafts, packrafts and cheaper IKs, this Chinese brand would include a Boston valve nozzle. Luckily, I’ve amassed loads of adaptors and nozzles, and one 16mm (5/8″) adaptor fitted the pump’s main nozzle and jammed into the Boston port. [The orange Max Pump Plus included a nozzle for the valved port].

Off a laptop allow two hours to fully charge the pump out of the box. After just three fills (12 mins?), it took just hour or less to get the green light. Off the mains is faster.

I estimate the volume of my Rebel 2K was 240 litres, (12 jerricans) so at the claimed flow rate of 300 L/min (currently the highest in Flextailgear’s range of mini pumps), that ought to take less than a minute. In fact it took 2:30s to reach the equivalent of airbag pressure (full volume; above).
But this was pushing through the one-way valve, (like a car tyre) not direct into the hull via the airbag port / dump valve which has no resistance.
Now with a bigger TXL with a volume of around 350 litres, I inflate directly through the screw port into the hull: 2:20s and if you’re quick you don’t lose much air screwing the cap on. Then I Flex for another 30s via the valve (or do 20 breaths to save the battery) and finish off with the handpump.
According to the Flextailgear table above, my heavier orange Max Pump Plus has 10% less power and max pressure than the Max Pump, but it’s hard to verify any of this data other than weight. The fact is, either pump does a packraft in a couple of minutes. Max Pump Plus: 170g + nozzles.

My comfy full-length Exped Synmat XP 9LW – which also needs air-bagging to avoid humid breath – inflates in just 25s. And as many will know, air-bagging a sleeping mat in a cramped tent when you’re worn out is not one of the joys of camping.
The Max 2020’s 3600mAH lithium battery is claimed to run for 40 minutes, so that ought to do at least 10-15 raft fills plus a few mats, when camping. I imagine the Max Plus will be the same.

Deflating either of these items is of course as easy as rolling them up, but getting the last bit of air out can be tricky, even though it can save a lot of packed volume. Pump suction definitely works on my Seawave IK because the one-way valve can be pulled open with the bayonet nozzle. On the packraft and mat, you have to suck from the unvalved airbag port, and by the time you’ve plugged that, some air gets drawn back in. I find just rolling up, squeezing, then sucking the last of the air by mouth works best, as your hands are free to get to the valve cap fast.

Max Pump Plus will do my Anfibio TXL in under 3 mins

Last word to Sven from Anfibio: “Can’t live without one anymore. Cannot remember when I last used an inflation bag.”
These young people, honestly. 

Kayaking Summer Isles; a lap of the Taneras

Seawave Index Page
Summer Isles Kayaking Guide
Other Summer Isles paddles

Another forecast of calm winds in the Summers. Or is it? The BBC and YR reports are contradictory: the former has too-strong-for-IK winds from the south; the latter shows light winds from the north. Others show light winds from the south. How can they all be so different?
Maybe I should just look out across the water? All looks serene so let’s make paddle while the sun shines. I wheel back down to False Man’s Harbour and set off with two hours before high water.

No side PRVs?
Am I missing not having added pressure release valves in my side tubes, as I did to my original Seawave? Not really. I am running 0.3+ bar in the sides (official: 0.25) but temperatures up here in NW Scotland are hardly tropical. I try and leave the boat in the shade at the house and de-air the side tubes for a couple of seconds after a paddle, effectively manually depressurising the sides to about 0.2 bar, rather than having fitted PRVs do it for me automatically. The more vulnerable stock PRV in the floor purges automatically at 0.25.
On my next paddle I have to top up all three chambers with the K-Pump as I would have to do with all-round PRVs anyway. About 30 kpumps brings the sides back up to over 0.3 bar. The difference now is I use a manometer to check the sides are about right. Before I would just pump until the side PRVs purged. It’s about a minute’s more faffing.
As with a lot of things I do to my IKs: sails, rudders, decks and now, trolleys and headwind weight transfer – it’s fun to experiment. But in the end they’re all largely over-shadowed by the simple enjoyment of paddling. With sides pumped to >0.3 bar I find I can cruise easily in the near-still conditions at 6kph.

Let’s try and make the outside of Tanera Beg again. Two days ago I got blown off that idea.
Kayaking tour party mustering at the north cliff of T. Beg.
But they seem to be dawdling, as if unsure whether to go ahead.
I paddle past and on to the big cave on T. Beg’s south side. That crack at the back might be passable at max HW.
The view out south towards the Wedge of Angus and Priest Island beyond.
I slip through the popular arch at Tanera Beg’s southeast end.
I notice a small second arch. The water is too high and gap too narrow to squeeze through with my Seawave, but it’s only a foot deep below, so the window of opportunity is as narrow as the arch.
What would Freud have made of all this arch-threading.
Being more exposed to the southwest, Tanera Beg has some deeply weathered sandstone cliffs.
Midway through, I decide crossing over to Tanera Mor seems too easy.
In the prevailing calm the three skerries to the south don’t look that far.
It’s just over a kilometre to Sgeir Ribhinn (‘Stack C’) according to the GPS. That will take 11 minutes.
Once there, I fail to notice the double-arched cave we found last time. But this is HW. A guard-bird observes.
Over to the south side of Tanera Mor. The new owner is employing scores and spending millions here. New cottages here and there, plus tracks to isolated beaches (for building stones, I was told). They now ask you not to land in the more built-up Anchorage on the north side.
There’s even a new house and other construction alongside the tidal lagoon of An Lochanach where I stop for a snack.
Two kayakers pass by. Earlier, I could clearly hear them talking behind me across the flat water, long before I could see them.
I cross the Bay and stop off on the mainland below our place to collect something.
Looking west: a buoy with Glas Leac Mor behind.
I recently read that a hazy horizon (Outer Hebrides not visible) means stability; warm, humid air.
Good viz and crisp detail = cold air and wind.
I head to Altandu, near the campervan-packed campsite.
I drop-off and pick up a bucket. Coming back through Old Dornie harbour, a quarter headwind kicks up, pushing the bow left.
I use the chance to load the bow with 10 litres of bucket-water. It does seem to make a difference: the bow bites better; no correctional paddling needed, unlike the other day. A good trick to know (I’d brought the drybag up front for that purpose).
Another 13-mile day in the Summers, but I could have managed twice as far.
How easy IK-ing is without wind. As is portaging with a trolley.

Landfall on Eilean Mullagrach

Seawave Index Page
Summer Isles Kayaking Guide
Other Summer Isles paddles

After a fortnight of chilly north winds and a diminishing woodpile, today was one of those rare days in the Summer Isles (far northwest Scotland) where you could paddle pretty much where you liked in an IK.
It was also a chance for me to try out my new skeg-wheel trolley which Jon, who was staying down the road, had made for me.
With no boat of his own this time, we set off in mine to see what we might see.

We rolled down the road to the Fox Point, the nearest and least effortful shore access from where I’m staying.
Apart from the clatter of the solid wheels, the set up worked perfectly: stable and smooth.
The spring tide had bottomed out so we looked for the least ankle-twisting put-in.
We have no plan so head towards the Ristol Islands across a glassy sea.
With the calm, we take on the outside shore of Eilean Mullagrach; here the refracting northern after-swell makes it a bit choppier with some alarming waves breaking over reefs.
Unless you’re a gannet, this is the only way to get onto Mullagrach, a gantry at the northeast tip.
Usually alone, I’ve never done it, but with Jon to tend the boat, I climb up.
With access so difficult, Eilean Mullagrach was never occupied or crofted. I think it’s now owned by a bird protection enterprise. Perhaps they built this guardrail and cut the steps. There’s what looks like a hut at the island’s south end, just past the (not very) high point.
Nice to see sea pink and yellow lichen again. The former mostly found on the sheep-free islands and skerries.
View south over the Summers to the Fisherfield mountains.
The channel with Ristol behind. Better get back; the taxi’s meter is running.
We scoot back north out of the channel and take a break on Ristol beach before cutting through Old Dornie harbour back to False Man inlet.
I leave my kayak overnight with a plan to come back for more tomorrow.
Next morning I’m relieved to see my Seawave hasn’t floated off into the Minch.
I top up and decide to head round the outside of Tanera Beg for starters.
All is calmish as I cross Badentarbet Bay, but as I near T. Beg an unforecast southeasterly kicks up and keeps on kicking.
The west side of Tanera Beg would be too exposed, so I divert into the Tanera Channel, using the lee of the smaller eileans.
Nice looking wooden trawler.
I’m hoping to at least visit the arch at the southeast end of T. Beg.
It’s only 500m away but it’s quite lively and gusty now so I don’t risk it.
Instead, I turn east to get into the lee of Tanera Mor, and take a diversion through the usually cut off pool of Acairseid Driseach (these Gaelic words just roll off the tongue).
A bit disappointed, I head back to slot harbour but the wind seems less bad or may have passed.
So I collect my trolley and strike out for Horse & Goat Island.
I estimate it’s about 2 miles across Badentarbet Bay. The wind drops and even becomes a NW tail breeze.
It’s actually more like 3.5 miles to the tidal channel between Horse & Goat.
By now the spring tide is at full flow against me and I wonder if the two islands have joined up yet.
I needn’t have worried; the NW breeze is stronger than any tidal current and there’s at least a foot of clearance.
I pull over for a snack and a drink. Last time I was here was with my failed Semperit project. What a nice boat that could have been.
I knew from here it would be a 2-mile into the wind hack to Badentarbet beach.
Or even more annoyingly, a three-quarter headwind. It’s less than 10mph, but despite pushing hard with my left arm, the boat kept getting pushed right. Where is my rudder now?! I should have picked up some rocks to weight the bow at Horse Island to see if that trick works. Next time I’ll carry a waterbag to do the same; it’s something I’ve read of but never tried.
From Badentarbet Beach it’s a stiff climb – 1st gear pushbike – back up the road to Polbain, but on the road the skeg-wheel trolley again makes for easy, hands free towing with the boat hanging from my shoulder via a knotted mooring line. I can walk at normal speed with loads less effort (and time) than carrying the deflated IK.
Having a trolley like this makes the IK nearly as versatile as a packraft: a boat you can start here, end there and easily transport back across the difference.

So ends another great 12-mile day out in the Summer Isles whose configuration enables numerous ways to spin out a trip as pirates, winds and stamina allow, and all without getting too far out.

Gumotex Slip-On Skeg Roller (kayak trolley)

The effort of portaging the dozen locks of the River Wey the other month wore me out. On some portages you can drag the boat along harmlessly on lush grass. Others involved narrow gates, or crossing busy or narrow road bridges. It all got quite effortful, especially towards the end as my energy faded like a dying salmon.

I quickly worked out what was needed: a simple and easily deployed alternative to the typical strap-on canoe trolley, like the 60 quid Decathlon example (left) with identical examples on eBay for nearly half that price. A closer look at some images shows them to be needlessly high (unstable) and the clip-out joints don’t look that sturdy in the long run, though the tyres are nice and fat and clearance is great. With these trolleys I think the V of the alloy frame would sit better in line with the hull, not across it (with bends in the tubes). But crossways simplifies the wheel axle set up. My idea was to use the IK’s own weight with the skeg to locate and fix a trolley in place. Quick to use; no strapping needed.

With workspace-and-tools mate Jon, we came up with a stable two-wheel folding platform with a drop-in skeg slot and hinged wheels which folded out to both roll and support the hull either side of the skeg. To portage, lower the boat’s skeg into the platform’s slot, pick up at the bow and roll it away.

On getting the trolley, the too-high sides were easily sawn down by an inch, and another inch got sawn off the bottom to improve ground clearance, as in the graphic. We hadn’t pinned down a way of stopping the hinged wheel plates folding inwards on the move. The trolley actually worked OK on smooth surfaces without any hinge lock, but eventually a bump would knock one side in. Until a neater idea springs to mind, the easiest way for me was stringing a loop of stretch-free Dyneema cord round the top to keep the wheel plates from folding in.

At 1.7kg it’s not that light, but as a prototype it was dead easy to make and the thing needs to be durable. Something similar out of alloy tubing (like the Decathlon trolley above) might be half the weight, but is less easy to fabricate in the front garden.

After a few miles…
By chance, I was left car-less during a few days of great weather. In either direction it’s less than a mile and a 50-metre drop along a quiet road to the seashore: an ideal trolley testing scenario. What extra weight there is sits best over the wheels, and at the bow I tie a shoulder loop into the mooring line, leaving me hands-free to check my messages. Coming uphill for a mile from the beach, I could walk at normal speed with much less effort (and time) than carrying the deflated IK.
It seems the width and height proportions are pretty good for stability, and the cord works well enough to keep the hinged sides up. A couple of times over rough stony ground the cord came off and the trolley folded up, or on steeper side slopes it just fell over. So maybe another 10-15cm of width would be good, but without much added height. And there must be a simple latch or lock idea for securing the sides.

The solid plastic wheels (£12.50 for two pairs) make a racket or hard surfaces and will transfer shocks and eventual wear to the wheel mounts. Some near-identical rubber wheels cost about the same and ought to feel less harsh. But first, I may waste some time wrapping some spare motorbike inner tube around my current wheels.

Having a trolley makes an IK nearly as versatile as a packraft: a boat you can start here, end there and easily transport back across the difference.

Packrafting the River Wye

Rebel 2K main page

With the exception of a few rivers … (Lugg … Severn … and the Wye), there is no confirmed Public Right of Navigation on other physically navigable, non-tidal rivers in Wales.

The Wye is the only river in (mostly) England where you can paddle for days and over a hundred miles, and not need to dodge a weir, portage a lock or confront a scowling angler. Even the few towns are historically intriguing. The whole valley is an Area of Outstanding Natural Beauty (‘AONB’), or ‘countryside’ as some call it.
You don’t even need a BC licence: from Hay-on-Wye the river uniquely has PRN (‘public right of navigation’; like a footpath’s ‘right of way’). There is no other river like it in England so I don’t know what’s taken me so long, other than the prospect of another staycated summer makes you reappraise your own backyard.

I invited myself to join Barry who lives near the river and who’d just bought himself an MRS Nomad. He’d done Hay to Hereford once and pronounced it a bit tame, so proposed Hoarwithy (Mile 51 from Hay) to the tidal finale at Chepstow (Mile 107 according to the table, left, or Mile 100 in the same sourced EA pdf guide.

Fifty-odd miles: two long days and a bit, we estimated (wrongly). Our riverine transit had to be timed to meet HW at Brockweir, 7 miles from Chepstow’s sole jetty, otherwise we’d be stranded by tidal sludge or swept out into the Severn and end up in Tristan da Cunha.

Chepstow jetty at LW; messy.

I don’t think I’ve ever seen a tidal profile like Chepstow: on a Spring tide the water can rise nearly 9 metres is less than two and a half hours, then take over ten hours to drop. This is because your Atlantic Ocean is piling into the western edge of the European land mass, including the funnel of the Severn (with Wye) estuary, creating among the highest tides on the whole darn planet. The game of ‘grab the jetty’ would make an exciting conclusion to our trip, especially as we’d have to be on the water before dawn to time it right. The guidebook warns: continue beyond Chepstow at your peril. Most canoeists dodge the tide timing game and take out at Brockweir.

I thought I’d do the Wye in my Seawave, but then decided all that space and speed and glide would be too easy. Anfibio did me a deal on the Rebel 2K I tested last autumn (they’ll readily drop the tax to the UK so you don’t pay it twice). The three-night paddle would be a good test of their internal storage system for packraft touring. And the wet bits in between, a good test of the boat. My review of the 2K here.
Short version: with a good, rain-fed current, the Wye is a fabulous, easy and scenic paddle. We saw just a couple of Gumo Safaris on a bank, and some club rowers out of Ross. Plus loads of parked up canoes waiting for the rental season. I hope to do it again in the summer. With no lifts, I’d try to leave Hereford early for Symmonds Yat free camp (see below). It’s 43 miles but in the conditions we had could be an easy ten hours. And if you don’t make it, no bother. Then it’s five hours paddling to Brockweir where an early afternoon HW could bring you two hours into Chepstow for a train home.

Wax your paddle blades to reduce drips

IKs are mostly undecked and drips from the swinging paddle can be a bit of an annoyance on a chilly day if you’re not wearing waterproofs. A solution in three words: Wax Your Blades.

More than three words
After watching the vid above I found some Nikwax Solarproof (left) under the kitchen sink. As well as being a UV protectorant (like the Aero 303 spray I’ve used for years), it adds water repellency to outdoor fabric gear like tents and jackets.
Now that it’ll be out for weeks, I sprayed my Seawave 2 and noted the boat was slipperier than usual when we lashed it to the car roof to go for a paddle. Should glide better on the water, too.
I also sprayed Solarproof on one paddle blade and in the sink noted the unsprayed blade took over twice as long to dribble dry (4-5 secs), but the coated blade still brought some water up with it.

Out paddling on the water, I can’t say the coating made that much difference because, as in the video above, your paddle is typically out of the water and swinging forward for a second or two – not long enough for the Solarproofed paddle to shed its water.
However, his wax version did seem to shed near-instantly. So I beeswaxed the untreated blade and noticed wax sheds water as fast as the sprayed paddle did alongside the untreated one.
Conclusion: water repellant spray works and has UV benefits, but wax sheds water better and probably lasts longer, too.
