A few years ago I persuaded various paddling chums to buy cheap PVC pool toys. If I’d known these boats were around earlier, they’re something I may have tried myself before buying my first Alpacka. Check out my posts on the Intex SeaHawk 1 and 2 dinghies on rivers and sea here, here and here plus here and also here.
To the untrained eye a PVC dinghy looks like a real packraft – until you paddle one that is. For the money spent there’s little to lose, although there’s much to be lost when the thing develops a leak as you cross the Solway Firth.
Knowing what I now know, having done multi-day tours with mates in France, Scotland and Australia in slackrafts, my feeling is that the construction of these ultra-cheapies – seams and fittings – is actually fairly reliable, it’s usually the material – soft PVC film with no fabric core like a proper pack boat, which lets them down when they snag or get abraded.
That, and the excessively wide hull that’s actually designed and shaped for rowing (above left) are the main flaws. For paddling you have to propel the boat ‘backwards’ with the squared-off stern pointing forward (left), because the additional paddler’s buoyancy is designed into the rounded bow (much as the pointy ‘fastback’ Alpackas design it into the stern). You can sit at- or on the stern of a pool toy (we’ve tried all ways – see video below), but there’s little draught there. Depending on your weight, you may swamp the boat.
In 2011 Steve and I paddled on the Chassezac and Ardeche in France (left – bow forward, bag in the boat) in a £38 Intex Sea Hawk II before Steve’s boat got too ruined (right) and was binned after three days. It could have been repaired but there were SoT rentals nearby, so Steve continued with one of those as by this time paddling a boat full of water had lost its shine.
With Jon in a 1-man Sea Hawk I (£20, top of page), we goofed about off Achnahaird in Scotland. And I covered six days on the with Jeff in a Bestway Outdoorsman (£20, below left), a pool toy that’s designed to be used only with adult supervision. He caught a few punctures but still finished the run.
My Alpacka Yaks are ten times better than all these boats put together, but are they worth 25 times the price? The answer is probably yes. It will last 28 times longer and certainly give 32 times more paddling enjoyment. Experienced sea and WW paddler Jeff couldn’t wait to see the back of his Bestway at the end of the Fitzroy River; at the bridge he gave it away to some local kids (right).
Paddling stern first doesn’t help, but another reason these boats paddle slowly is because they’re limp and over-wide – typically achieving 60% of a new-shape Alpacka’s top speed as we found in the Kimberley (3kph v 5kph) see the video above. Width means stability, safety and wholesome family fun. Most buyers of these kind of boats don’t give a toss about speed as the idea of day-long paddles, let alone overnight touring is patently absurd.
There’s not much you can do about the limp pressure because, lacking a stretch-proof fabric core, pure PVC expands like a party balloon.
These pool toys often have crude guide marks on the hull (left) to make sure you don’t over-inflate them. Proper packraft material doesn’t stretch so you’d notice. When they’re full, they’re full and most manage that with just lung pressure. If two of you pick up an Alpacka from either end with a backpack inside it, it stays pretty rigid. An Intex or Bestway will fold like a lilo.
Still, there must be something that fills the gap between these disposable toys and a £600 Alpacka. I suppose some of the very light single-coated nylon crossrafts listed here from $200 to $500. But they still have a poor reputation for durability and are more fun to carry than paddle. Certainly the PU-coated nylon seats on my Alpackas have failed through bad seals or at the valve.
Then I got an email from Narwhal showing me how he’d cut off the outer chamber of his £32 Sevy Super Caravelle to get a much lighter, noticeably narrower and more roll-up compact boat. The squared-off stern stern is reduced too. I’m sure you could do the same to an Intex or similar.
As you can see from the generic Sevy graphic above left, the outer hull is not the main bulk of the buoyancy, despite what appearances suggest. Of course, no matter what Sevy claim, it’s still made of shite PVC with no fabric core, but I get the feeling the ‘Super Caravelle’ range is to the plain Sevy Caravelles what the ‘Sea Hawk’ brand of Intex is to their cheaper pool toy- and lake boat ranges: a slighter thicker PVC with multiple chambers, manages to earn some nominal US NMMA marine safety certification. It has an I-beam floor too, but you’ll still have to be a lot more careful with it than an Alpacka or similar. The warranty is only 90 days but if it lasts longer than that you do automatically get a telegram from the Queen.
You can get a bit blasé to an Alpacka’s toughness. It was so nice on the Fitzroy in Australia to treat it almost like a hardshell, while Jeff had to nurse his Bestway all the way, and then still repair three flats.
Once peeled of its excess, suddenly Narwhal’s bloat acquired proportions one could do business with, even at the cost of a little buoyancy. Like most people, he’s 15-kilos lighter than me, but his pack in the photos was a deliberately heavy 25kg which is 10kg more than you’d carry in the field, even in winter. And a great side benefit is you get to lose all those naff pool-toy graphics and branding! That alone is worth at least £29.95 inc. VAT.
As Narwhal explains:
I did this with my 32 quid Sevylor Super Caravelle this summer – ran the Lugg and parts of the Wye and Severn on it, crap water levels but still satisfying.
Rucksack has over 25kg in so it’s severely weighing me down as a deliberate test as I’m just on our pond.
Weight is now 1680 grams [3.7lbs – my modified Yak is about double that] with excessively and messily glued attachment points, it was 1596 before attaching them.
Tubes are roughly 8 1/2 inches in diameter. [Alpackas are 10″]
Length – 163cm or 64 inches [My Yak is 88″, old Llama was 80″]
Width 83cm / 33 inches [Most Alpackas are 36″]
Inner length – 107 ish cms / 42″ [Yak is 46″, Llama 51″]
Inner width – 43 cm ish / 17″ [My Yak/Llama 14″]
(For comparison, full Alpacka dims here)
I’m 5’11 and 78kg and I was sitting a bit wonkily, did get back in to check it’s not always like that. You still need an effing huge and annoying pump if you want to inflate it nicely, but it handles so so much nicer than before. Now need to get myself a wetsuit and take it out in the east of Scotland, my new habitat. You might even be able to scavenge from pfds out of the two sausage-chamber keels that get cut off too [see graphic above], didn’t think about that, they stay intact so it’s possible.
On the Ardeche Steve and I did talk about cutting off his outer chamber to speed the boat up. It’s now clear from the Sevy graphic (above) that that doesn’t mean you lose masses of volume and so buoyancy. And of course you can use that excess material to beef up the vulnerable areas – under the heels, the bow and stern and probably the butt – or cut out and re-use the mounts as Narwhal did.
Packraft historians will see that Narwhal’s cut-down Super Carousel bears a passing resemblance to Sevylor’s some-might-say legendary Trail Boat (right) which I believe is no longer made (possibly because subsequent US safety regs required multiple chambers to gain type approval). Clearly designed to paddle narrow bow forward, and not row, the Trail Boat looks like one of them Al-Packers! And is that an elbow valve I see in the top left corner? Suggests that it could be lung inflated or topped up. There’s another one on the yellow thing – a seat? There’s a good discussion about the late Trail Boat on BPL, to which I’ve added my couple of cents.
The question is, is it worth the effort to still have a fragile-skinned packraft, even if it’s quicker than its multi-chamber donor blob? I think it is if you’re baulking at ordering an Alpacka. And at least Sevylor is a dedicated inflatable boat maker and not a Chinese, anything-you-like-in-PVC factory like Intex. After all, Sevylor were the original inflatables.
As Narwhal observes, he’s ended up with a 1.6-kilo slackraft (a kilo less than an Alpacka) including glued-on attachment points, and that can still carry a hefty load. The ‘air draught’ looks a bit low which means easy swamping with heavy folk, but that only matters if you’re not dressed right or are where you shouldn’t be in a £30 paddling pool.
Anyway, for thirty-odd quid I couldn’t resist it and have tried ordering a Super C to implement Narwhal’s canny mods. They were out of stock in the UK so I ended up with the thinner Caravelle (14 gauge not 16g – a fraction of a mm, AFAICT). If nothing else it’ll make a nifty little guest boat and as I have a sheet of ‘ballistic nylon’ lying around I glued that onto the Cara’s floor to make a boat for the g-friend.
For the real thing I’ll always have my Alpacka Yak, which after Australia has proved itself as a tough old boat. But then for what I paid, so it should be. Thanks to Narwhal for the photos and the idea of trimming an over-wide bloat into a super cheap pack raft.
