Hi,
Inspired by Tim’s catyak http://www.cubenmaker.com/?2
I wanted to make an easier to assemble catyak, with minimal rigid frame. I knew I will face difficulties and failures but hoped to find solutions. So after a lot of thinking and welding , I made it . Unfortunately as you can see at picture, the fabric sockets holding the crossbars…[Read more]

pweissma replied to the topic Top-up valve adapter for boston valve in the forum DIY Packrafts 3 years, 1 month ago
I took a boston valve pump adapter and glued a piece of vinyl tubing to the inside. It has a snug fit in the valve and works great for top-off.
On my ultralight I installed a Leakfield c7 valve. For this, the standard c7 screw-in valve adapter can be used but NRS sells a rubber pressure fit adapter that I use for top-off.

Replacement Spray Deck Stiffener
The DIY Packraft spray decks use flexible plastic tubing to stiffen the rim that the elastic spray skirt fits over (the coaming), and several […]-
is there a way to tell between the two batches? I got a kit six months ago and haven’t put it together yet. Should I just to put it together with Pex out of an abundance of caution?
-
I don’t think there’s an easy way to tell, but the stiffener is something that you insert and remove each time you use the packraft, so you don’t really need to worry about it beforehand – if it’s not stiff enough to keep the skirt on when you get to that point then you can replace it.

Thanks for addressing this issue, Matt. I found that with 1/2″ PEX-b for combing, the spray skirt stays fairly well attached to the spray deck through class III. However, it’s still far from dry in that boat. As my body rotates while paddling through whitewater, the waist shock-cord tends to drop down my waist until it sits quite low. Water then pools on the skirt and slowly drips through my shirt and into the cockpit. After running my local 2 mile stretch of whitewater, I had 50-70lbs of water in the boat. So while it won’t negate the need for a drysuit in cold conditions, it does at least prevent having to get out & dump the boat after every rapid. I think my next adjustment will be adding shoulder straps to the skirt to keep it higher on my waist. After that, I may look at aquasealing the holes along the deck where the tube-fabric-joining strips prevent a seal, as you suggest in the tutorial.

I found the same issue with the skirt. You can correct this by adding adjustable straps to your skirt. These will prevent the skirt from gradually shifting down. I also found I needed to add additional fabric panels to offer more ‘give’ to the skirt, allowing me to shift around in the boat a bit more without putting tension on the skirt.

Matt (Admin) replied to the topic Creases between Tubes 3 and 2 in the forum DIY Packrafts 3 years, 2 months ago
If you pull the tube 2 fabric forward and align the edge with the 5 cm line beside the slit (letting the tube fabric overhang the slit) then it looks like it will lie flat. You don’t have to force the existing corner to sit on the slit – you can trim the forward edge of tube 2 later so it lines up with the slit.
Does that help? I’m not 100% sure…[Read more]

Hey there,
So despite seemingly following the instructions, I will end up with creases between tubes two and three if I place tube two on the required line at the bottom (black piece).

Any suggestions on how to fix it? Can I just heat seal the bunched up part and add an extra layer accordingly?

Hi! Found your site a couple weeks ago via YouTube and looking at buying the Ultralight packraft kit to bring along on my backpacking trips to alpine lakes in Washington state.

New Heat Sealing Video
As part of my effort to continuously improve the DIY Packraft instructions, I’ve made a new, more comprehensive video about heat sealing. It’s […]-
Great Video. I’m just about to start assembling my second packraft and I know my sealing technique needs improvements. After using he first packraft a few times I found the edge of the seams would develop little bubbles of delamination between the TPU layers which I spot hit with the iron. I think not having to move the iron back and forth along the seams during the sealing will help me get a better initial weld.

Matt (Admin) replied to the topic DIY Packraft Photos in the forum DIY Packrafts 3 years, 2 months ago
Hi Christian, I sympathize with that fear! It took me some time before I felt comfortable paddling in the Ultralight packrafts. The newer Ultralight fabric is very similar to the older fabric – to achieve the packraft’s very light weight we must use a very lightweight fabric or reduce the size and capabilities of the boat.
As a confidence…[Read more]
