Anfibio Rebel 2K Index Page
In a line Huge. 1.3m downwind disc sail supported by an inflatable hoop and which rolls down into a small bundle.
Cost €149 from Anfibio Store.
Weight (verified): 513g.
Where used Loch Hourn, off Knoydart, Scotland (on my Anfibio 2K, and alongside an MRS Nomad S1).
Rolls up compact (unlike framed versions)
Big surface area
Unexpectedly stable, controllable and steerable
As long as you’re not using a deck, it can be temporarily pulled down and tucked under the knees when not wanted
A 3.5-m long Nomad S1 can move at up to 5mph in strong gusts
Uses the same valve and pump as the packraft
Doubles as a tent footprint or mini-tarp or even a brolly
Window is too high (on a fat-bowed packraft)
On a regular sized packraft, sailing might be slower than you think
About 20% more expensive than Anfibio’s same-diameter PackSail
Punctures or twisted bladder more likely than a broken batten?
The AirSail was supplied free by Anfibio for testing and review.
What They Say
The first packraft sail of its kind! The light, inflatable AirSail gets your packraft going and lets you experience speed even on calm waters. The sail creates completely new possibilities to be on tour with the Packraft. Only 466g and minimal packing size.
On a multi-day packrafting trip or where you’re not returning the same way into the wind, sailing downwind is a smart means of conserving energy while enjoying a look around. At any other time, it’s just plain fun. Until now, the only options for packrafts were flexible, spring-out WindPaddle disc sails and their many inferior knock-offs. I’ve made my own and tried both, and currently own a WP Adventure 2 which has been OK on the Seawave IK and my old MRS Nomad, and even better on the Rebel 2K.
The Anfibio AirSail differs by using an inflatable bladder ring inside a fabric rim casing which you inflate via a Boston valve with the same 10-euro mini hand pump you use to top up the boat. The sail’s outer diameter is 137cm, so the sail is close to 130cm, as stated. Surprisingly, it seems to be possible to achieve as effective levels of stiffness to a flexible batten disc sail – a key to consistent performance – while an AirSail packs down to the size of a sleeping pad. My WindPaddle folds down to a flat, 40-cm disc which some might find more awkward to pack on the trail, though I can’t say I did.
Alone, out on the water in windy conditions it would be tricky to deploy the AirSail. Assuming a skeg is fitted and the sail’s already clipped to the bow via a couple of mini-karabiners, you need to reach forward to unstrap the sail (hard in my 2K with a deck zipped up), unfurl to unkink it, plug in your mini pump and give it two dozen jabs to fully inflate – all without being blown around or losing your paddle. Were I doing this, I’d add a short ‘haul-line’ to the base of the sail so I could pull it back into arm’s reach.
I chose to do all this by the shore in the lee of a headland. I started with my electric Flex Pump but for some reason it didn’t do much, considering the small volume. It was the same next time, so in future I’d go straight to mini hand pump which needs around 25 pumps.
From my experiences with the WindPaddle on kayak and packraft, I was a bit nervous the even bigger AirSail might be a handful. I needn’t have worried. Funnelled down the steep-sided Loch Hourn, winds gusted to 15mph, but the Rebel 2K with the AirSail was easy to manage in a way the WindPaddle 2 never has been so far on other boats. And this was with an under-inflated air ring. There was no violent see-sawing from side to side, little need for constant correction and, considering I was out in the middle of a windy sea loch, I felt safe and in control. My paddle was leashed to the mooring line but also slipped securely under and out of the way underneath the DeckPack.
This plain sailing was partly because the 2K could not break into a gallop. I doubt I was going much faster than paddling, but it sure was effortless and relaxing. Had there been a signal I could have easily updated my profile on Insta or checked the forecast. The 4km which had taken me an increasingly slower 80 minutes, was covered downwind in an effortless 60 minutes
I also think the low centre of gravity of the loaded 2K helped it sit on the water and – crucially – the lack of slack between the sail and boat fittings kept the under-inflated sail from swaying. I must try this taught rigging on the kayak next time; that could have been my problem all along.
With the line clipped to a karabiner on my pfd or behind my head, most of the time I was sailing hands free which made filming easy. The line was just the right length, too. Only tiny tweaks were needed to keep the boat on line, due to the back getting blown round. This was most probably down to the small skeg, but was all much less frantic than my recent sail with the WP on the Seawave. I suppose with free hands, the paddle could have been used as rudder to maintain a heading, but I didn’t think to try that as I was going vaguely in the right direction. Something to try next time.
One problem with the AirSail: because the bow on a 2K is high compared to a kayak, the window is too high to see what’s ahead; it’s the lower third which needs a clear PVC pane. Most of the time it doesn’t matter; you can lower the sail or look around. In fact, it would be great if the whole thing was made of clear film, but weight, rolled volume or strength may not add up.
With the line out of your hands it’s easy to try and add a bit of speed by paddling as well, but at best this might add a tiny bit of speed and will help keep you warm. You do notice that not paddling can chill you. Once you’ve had a good look around, after being used to having to paddle every hard-won metre, sailing slowly might even be said to be a little boring unless the winds are strong,. But on a long day on a multi-day tour, you’ll welcome the break when you get a chance, as we did on Knoydart.
As you can see, a couple of weeks later I travelled with a mate in an MRS Nomad S1 using the same Anfibio AirSail, with me WindPaddling in my 2K. The longer Nomad is a bit faster than my 2K, and with the AirSail was quite a lot faster, maybe 15%, especially in strong winds. That meant that the Nomad had to stop to wait for me to catch up, which also proved that the AirSail could be pulled back and tucked out of the way under the knees. The added space up front on the Nomad makes this easier than in a regular packraft, but requires not using a deck, unless some sort of cross-strap arrangement is set up to hold the sail down.
Sailing in squalls of up to 25mph took quite a lot of concentration but never felt unsafe. The Nomad was reaching 5mph (8mph) but remained stable and controllable (as did my slower 2K with the WP sail). With both types of sail, this was sailing at its best: satisfying, safe but exciting too
The problem with sailing is you don’t generate any heat. We were already wet from a long walk before we got on the water, and neither of our hiking cags were up to it. After an hour or so of hanging on in torrential squalls, and with another two hours to the end of the loch, my mate in the undecked Nomad had to go ashore to drain his boat by which time both of us were chilled. We’d both tried paddle-sailing to warm up (and me, to catch up), but were too far gone to make a difference in the conditions that day. If you plan to paddle and sail an undecked packraft in all conditions, get a dry suit and maybe a bilge pump.
Having used the AirSail and paddled alongside one, I still think I’d choose the cheaper, same weight/ø, batten-rimmed PackSail. For me the value in being able to stow or release a sail in a few seconds is not offset by the slight awkwardness of needing to stash a 40-cm disc. But it’s nice to have the choice.
Thanks to Anfibio for supplying the AirSail.
