Alpacka WitchCraft

Brad and I hit Eagle River today and I paddled the Witchcraft fully outfitted with its ensemble X-Ray, foot bed and back rest. It was the first time I had dared all three components at once. And the first time I'd seen how they all work together.

An act of genius this boat is.

My earlier stints in the boat had either not fully inflated or not included all the pieces. That was clearly a mistake. The back rest makes me sit up straighter than my mother ever could. The foot bed offers a secure and familiar but much, much improved pushing platform common to non-thigh strap packrafts. And the X-ray, while a bit scary in concept and images, clearly adds benefits I have not seen with thigh straps, namely the "knee-cup" effect that so many kayakers would like in a packraft. I was able to role over and over and over and over (sweep rolls not C to C) in the icy cold river today and surfed more waves and play-holes than ever before. It's a joy to paddle.

The boat is faster forward than a conventional Alpacka but just as nimble. While tippier, the added control afforded by the X-Ray more than compensates for the tip and gives an incredible oneness/snugness with the craft. In fact it's neat to work on bracing out on the edge and sculling to keep it.

The boat was so much fun that I couldn't bring myself to accompany Brad back to the car below Campground Rapid and joined a trio of passing packrafters for an extended float down to the play hole on Base and beyond.

Thanks Alpacka for another great idea: a class V packraft. Now I just have to become a class V boater.

Vids of the Month

Yes it's time for the best packrafting vids of the month, this month being now and the best vids being these three:

Ganey's greatest hits from a Vermont Autumn mostly:



Forrest's cool Ski Raftineering trip in Wyoming with his wife Amy and the guy with really wild hair:




And this! A new raft design from Alpacka -- the WitchCraft (which craft?) -- being rolled without thighstraps:



Here's what Sheri of Alpacka Raft has to say about this new amazing boat:

"I have 3 of these in testing at the moment. After two salt trips this next week I suspect we will be ready to say "go for it". The suspension system is actually from above and is very firm. It has more grip and leverage on the thighs than the thigh straps do and there does not seem to be any entanglement issues with it. When the deck is pulled the system comes loose with the deck. I won't go into any more detail on that at the moment til the two Salt trips are completed and I am sure I am satisfied. That said, at this point it is looking really good. The stern on this boat has been elongated even further, another four inches, and the bow tubes are quite a bit smaller. The end result is the boat is trim with a person in it with no added weight. This boat is not intended to carry big loads, that is what the regular Alpacas are for. This boat is really designed to be trim and balanced in the water with just a person. This boat is being made with all floor fabric and a very beefed up deck that is actually glued on like the floor. Everything about this boat is aimed at being a more aggressive whitewater capability item. The weight looks like it will be around 8.5 lbs. So this isn't the long distance trip boat, it is meant to be the more day hike/trip front country mud truck white water oriented beast."

Can't wait to get my butt in that boat!

Thigh straps and rolling continued.

First off, they are rolling their packrafts in Europe!

Secondly, Alpacka's Sheri Tingey says in the Alpacka Forum to make sure you use Urethane-based D-ring patches.

Third, Luc Mehl has now got his roll at about 90-95%. His friend Dmitry was near 100% last week. I lag at a solid 50%, but managed several easily with 10 pounds in my boat: 5 pounds between my knees and lashed to the floor and 5 pounds behind my back in place of a backrest, again using the 15 L WXTex dry bags and accessory lash straps.

Also over at Backpackinglight.com in the packrafting forum is a good post by Richard Nisley on lightweight dry bottoms and top for cold weather packrafting instead of a full-on dry suit.

Pimping my ride.

This packrafting thing is eating me alive.
I'm paddling when I should be skiing -- and in a pool, no less, -- buying expensive, new stuff, like a 3 oz Tenkara fly-fishing rod to fit inside a 2 lb Sawyer packrafting paddle, and an airplane ticket to New Zealand. But most importantly I am modifying my boat, working on a Llama to make it the best wilderness whitewater boat in the world.
Now that I have rolled a packraft multiple times (more than a dozen!), and at about 50% success (albeit in a pool,) I wanna do it again and again. It's a fantastic feeling to be upside down and then roll on up, and "plop"! Super satisfying. It's like I have fallen in love with my boat all over again.
Last night four of us rolled over and over again in the APU pool.
Dmitry even rolled on his off-side, Luc rolled six times in a row, I rolled with a 5 pound load strapped between my knees, which, of course, Dmitry was able to do with strapped on his bow. Awesome!
By the way, Luc used Alpacka tie-downs for his thigh straps to save weight (1/4 oz vs. 1 0z) and money ($5 vs $15), but one ripped in half and off the boat last week! Word is they are only good to 300 lbs of force. He's back to the heavy D-ring wide diameter patches the rest of us have.
The Llama I am setting up for a month in New Zealand is a center opening, mid-oughts model (2006? My red boat is a 2005), pre-zipper, pre-backrest, pre-codpiece. Of course, it has thigh straps in the locations proven to work with a roll. The foot end of the thigh strap is near the floor, nine inches from the center bow seam, and the rear attachment is just above the valve, 33 inches away, remarkably similar to the inseam length of the Levi's I wear as I write this, which, as I am 49 years old, do not sag.
These thigh straps weigh a pound stock, so I took a tool to them and clipped off the big plastic buckles and trimmed off the 2-inch webbing, but left the loops that once held the plastic buckles and sliders. To attach the thigh straps I used shortish (like 12 inch) friction buckle accessory straps, 3/4 inch wide. Much lighter, and much more versatile than sewn on 2-inch. The thigh straps now weigh 11 oz. But they lack the quick release mechanism.
Next I set the seat free by cutting the stitches, then sewed the rear tab on the seat to the forward tab on the boat, conveniently moving the seat forward to just below the rear thigh strap attachment.
So what benefits does this give me? First it centers me in the boat making the bandersnatch less likely and allowing me to use a shorter paddle (197 cm, Werner Powerhouse, 37.8 oz, 4 piece), as I now sit forward and paddle over the narrowest part of the boat. The old placement of my seat put me paddling over the WIDEST part of the boat. This way I lighten the rear end of the boat, balancing the boat better, allowing use of a shorter paddle, and opening up gear storage space in back. It should reduce bandersnatching -- I checked this on Six Mile's 2nd and 3rd Canyons a month or so ago with my red boat and it's certainly true -- a centered seat equals a more balanced boat.
Ask anyone about Alpacka design issues and most mention that the Alpacka is too "back-heavy".
There are three typical responses to this design flaw:
(1) "Put weight on/in the bow." I think this is a a sub-optimal solution in whitewater. I need a light boat that responds quickly to my paddle strokes, so I eschew weight in general.
(2) "Make a bigger butt, or better yet, just make an inflatable kayak." I, for one, like the design of rounded bow and stern as the boat spins and turns more quickly and makes for a more novel craft. Besides, I can't afford a new boat.
(3) "Sit forward." Now, that's a solution I can agree with. Check out most other single-person boats and vehicles and see where the driver is located -- in the center.
The problem with the current Alpacka design is that the seat is so far back and glued in, that scooting forward sets up the bum for a bang on the bottom -- OUCH!
But in a standard, stock boat, sliding the seat forward means nothing to push against for the back, so there is no means of wedging yourself into the boat. Wedging into the boat is why Alpacka insists that you get the smallest boat that'll fit. But I find smaller boats are less stable than bigger boats. Still, "swimming" around inside a big boat gives poor control. That's where thigh straps come in.
So now that I am anchored in a big boat and don't need to shove my feet against the bow and my butt against the stern I can center the seat. To extend my legs, I slide off the thigh straps by extending my legs and let my feet go to the bow. Sweet!
So "What about a backrest?" you ask, loving that second toilet seat of your late-oughts model boat. You could either buy a "Fjord Explorer" seat, glue some 2 inch velcro on the boat and seat to keep it behind you as a new, removable backrest, and/or purchase one or two 15 liter P.O.E. WxTex dry bags and fill them with something soft, like your sleeping bag and sleep clothes, then glue in a single "strap plate" to secure the vertically oriented dry bag (glue the plate on the inside center of the rear-most seam).
Two strap plates on the floor of the boat, between the now bent knees held in position by thigh straps also allows a second 15 L POE WXTex dry bag that holding a tent and other camping gear/food to be secured near the center of gravity. The idea is that I am moving my gear off the bow and into the boat. There's still the opportunity for a bow load, but it is a bit smaller and by getting all the gear situated closer to the center of gravity, I can roll a loaded packraft. In the pool I tested this with five pounds and rolled it easily.
I doubt many are still reading such technical esoterica, but very soon I'll sew an additional two inches of velcro on the center opening of the deck making it more water tight. I will also have fixed the chronic Alpacka design flaw of sewing a draw string end to the outside edge of the waist velcro by using a second stitch. More importantly, abstracting the important design feature of the Meiklejohn commerbund, there'll soon be a bigger velcro closure on the top of the deck waist/belly-opening.
Finally, I will install a pair of pockets, one to either side of the waist/belly-opening at the top of the spray skirt. These will hold an air-filled 2 Liter Platypus. These Platypusses act as a water dam, obviating the need for a codpiece and keeping the easier wet (and dry for that matter) entry of a center opening boat.
Alpacka Rafts are now in a new stage of aftermarket design: aftermarket modifications now taking place with groups of individuals experimenting and learning from each other, as Thai Verzone, Hig Higman, Tracey Harmon, and I did last Saturday at Alaska Raft and Kayak (pic above).

Eskimo Roll a Packraft: No previous roll necessary!

First you need thigh straps.

Second you need to be able to get upside down in friendly water, a heated pool without chlorine seems ideal. Next while upside down reach your paddle up to the surface with blade flat and strong arm forward. Then pry yourself up with a sweep, keeping head and shoulders low until the boat's pretty much up (bow will be up more of course) and finally thrust that strong side hip toward the weak side, pulling against the thigh strap to get the final umph over, which is when you'll finally sit up.

I am no expert at this! I am just relaying what worked for us and what you can see is exactly what Tim Johnson is doing in the video.

NEWS FLASH: Three Mere Mortals Eskimo Roll Their Packrafts

None of the crew who'd put thigh straps in their boat could make it to the APU pool tonight where Tim Johnson, kayak expert and recent packraft Eskimo roller, was going to coach us.

Except Luc Mehl and me.

Luc invited his friends Galen and Dmitri, who paddled around in my yellow boat, while I got throughly confused on what I should be doing, other than trying to muscle over in the boat. I was getting nowhere.

Luc had managed a roll in the first 20 minutes or so with some tips from Galen, who once was a surf and sea kayak enthusiast. But then, like me, he floundered. At least he was getting his belly out of the water. I felt like I was just turning my boat from side to side underwater.

Meanwhile, Dmitri was off to the far end, doing his own thing. I'd actually written him off as just playing around in the packraft. Nobody seemed to be giving him any tips and I didn't hear any hooting and hollering -- until 9 PM, when I was just getting finished with hip snapping at the pool edge, which also was going nowhere.

It was getting time to leave. Tim had already gone into the locker room, no doubt amazed at how hapless, stiff, and uncoordinated I was.

"I probably will never be able to roll a packraft, even if glued to the thing," I thought.

Then I heard, "Do it again Dmitri!" and then watched in disbelief as he did what Luc had been doing all night and what anyone with thigh straps can do: get the upside down boat up to about a 45 degree angle by using the paddle in a standard kayak-style Eskimo-roll sweep. But he was finishing it off with a plop right side up!

Three times in a row he did it!

Paddling over to see what he did, I heard him recount the technique. He swept back with his arms to get up to the your-out-of-the-water stage, then hip thrust, "Like this," he gestured exaggerating his crunching hip movement.

I tipped over (I'd gotten good at that by now) came part way up Luc style and then hip thrust with a "Dmitri crunch", and BOOM -- I was over!

Awesome! I can't roll a kayak, and neither Luc nor Dmitri had ever rolled one. Now we were all rolling packrafts, long considered impossible to roll, then rolled recently but only by a kayaking expert.

Just to be sure I did it again. And again.

Luc was in the water now, paddling over to Dmitri to get his tuteleage -- then bam, bam he nailed two rolls in quick succession.

We'd done it!

Mere mortals, not kayak gods, had successfully rolled their packrafts and done it their own way.

Again -- awesome!

Thigh Straps: How-to

Five of us put thigh straps in our boats with Tracy Harmon’s supervision on Wednesday. We waited until Saturday, slightly longer than the 72 hour dry time, to go check out our new toys on Six Mile Creek at about 8.7 feet or 485 cfs.

It was fun to be with JT and hear him say “Let’s just skip the first canyon and run the second and third canyons,” as two years ago on Nov. 10, 2007 Becky, Tony, JT, Brad and I ran first and second canyons and my river notes record that they were hesitant to run the third canyon. How times change with skill and experience…..and how they will when more people start using thigh straps.

While nobody was able to repeat Timmy’s Eskimo roll (or his role, for that matter!), the straps make Six Mile at these low water levels almost easy. Minus my one mistake, we all had totally clean runs, including boofs in “Jaws”.

What really stood out was the incredible control and oneness with the boat.

“This is what kayakers miss in packrafts,” said JT, wiggling and pivoting with that big boyish grin of his.

I paddled open packrafts from 1983 to 2003, decked ones since then, and now these straps. They are at least as revolutionary as decks in terms of what you can do. Decks gave us control in bigger water since we weren’t just swamped and fighting for control. But these straps are even better.

Some of you may recall the early 1980s when Fires first came out. Remember that? The first time we got sticky rubber and we all started climbing a grade harder immediately? In fact, calling a +/- a grade in whitewater, I’d say these straps increased my ability by a grade. Six Mile was the easiest I’ve ever run it.

Control was incredible – I could put the boat almost anywhere. I could grab and ride smaller tongues than usual, brace more effectively, and catch eddies faster and with more authority – in fact flat water will be easier with these to brace against, too.

Busting out of holes requires aggression that you just can’t get flopping around unanchored in a boat. But with straps you can lean forward and grab and pull, “Like front-wheel drive,” someone said. Many of us have been working to wedge ourselves in to the boat, but tight thigh straps do it better.

And best of all my straps center me – I didn’t even use my back rest (it’s blown out anyway, with a shoddy valve job) and sat centered in the boat with the shortest paddle I have ever used (200 cm – as short as the Sawyer would go), able to reach forward and get good, aggressive powerful strokes. I am ready for 197 cm with big stiff blades, now.

I tipped in one of the worst parts of the river, and hit my head hard, maybe harder than I would’ve without straps -- although the gobs of Velcro I have keep me in, too -- but the straps slide off quickly and easily by straightening the legs.

It would be simple for Alpacka to put “custom mods” in their boats for people to purchase inflatable kayak thigh straps, like the Aire brand Deluxe Thigh Straps we used: On a Yak, a tie-down just above the valve stem and behind the second seam in the bow (calling the center seam the first) and close to the floor worked well for me following Tim Johnson’s lead.

Here’s a how to video. Hope it helps.

News Flash: Let the Revolution Begin.


We know that packrafts are real boats. The main problem has been that we users have not been seen as
real boaters.

Packrafts have been perceived as boats for people who can’t roll.

Until now.

Tim Johnson, author of Alaska Whitewater, bought a used packraft last week and did what we all want to do: he rolled it for real!

An Eskimo roll, twice, in Bird Creek with ice in the water and icicles on the cliffs.

This changes everything.

Anyone up for pool practice?
NB naysayers and armchair designers: The key were the bomber thigh straps he put in the boat.
