    2022 Packraft Build!

    2019 Edition: https://singletrackworld.com/forum/topic/packraft-build-2019/

    Bonus Story: mid-late 2020 a nice chap from Brazil came across the thread above and asked me to design a 2 person packraft for a multi-sport adventure race he organises (Malacara Race) – they ended up making 50+ I believe from PVC as they couldn’t source any Thermoplastic Poly Urethane/Nylon. I believe he’s started selling them.

    Anyway, the 2022 build is more what would be described as a “Pakyak”, I’ve seen a few emerging from various manufacturers and by all accounts they are significantly faster than the traditional Packraft shape (6km/h vs ~4km/h top speed)

    A spot of not-very-rapid prototyping:


    TPU 210d tube fabric, 420d bottom fabric

    Seams welded – *only* took 30mins per seam…

    Design and Prototyping time: 6hrs
    Build time so far ~15hrs

    Watch this space for end seams and test inflation…

    Awesome! That looks a really neat and compact craft.

    Just out of interest, how did you scale up the more complex sections from the prototype?

    Out of interest, what are you using to weld the seams at home? I’ve got a sleeping mat idea, which could be an interesting home build.

    All done in AutoCAD, just print it out full size on A1/0 sheets rather than an A3 sheet.

    I modified one of these: https://hobbyking.com/en_us/digital-led-sealing-iron-230v-eu-plug.html?wrh_pdp=1&utm_source=google&utm_medium=cpc&utm_campaign=google_gb_shopping&countrycode=GB&gclid=Cj0KCQjw1vSZBhDuARIsAKZlijQBewAJsY47bWi-nZ8vBpZD7T5JqUURULSQqOZctnlmbbqVuKugLdUaAoRtEALw_wcB&___store=en_us

    cut off the sides with a chop saw to leave a flat 9mmx 70mm rectangular heat iron (side of iron).

    The trouble is, it probably took about 20hrs to make, so I’d have to charge about £700!… which is about the price of a “professional” one!

    I reckon I’d get this if I were in the market: https://www.decathlon.co.uk/p/1-person-inflatable-river-packraft-kayak-100/_/R-p-332228

    Still WIP – still have a few details to add like seat, backrest etc. The skeg on the red one is 3D printed, so should just be a case of running another one off. Having said that, I believe this design will naturally track better anyway.

    in life sized, inflatable form?

    Sure, let me know a list of features you desire and I’ll knock something up

    alternatively, how much for the CAD plans and an idiot-proof bill of materials and construction sequence?

    If you want to stick it together yourself @ayjaydoubleyou have a look at iron raft, and let me know how you get on cos i’m interested myself.

    Bloody hell- how do you type out that username, the disconnect between the sound and the spelling did something uncomfortable to my brain!

    Iron raft is a great resource, their instructional videos take you through everything: https://youtube.com/channel/UChXzinYOJi5gJ9rFrfKZHMg

    A packraft kit from them is pretty good value tbh – £190ish which includes adhesive and a valve.

    I bought the TPU material from them this time round ~ 5m @ £17.50/m

    It’s a shame they only sell one design.

    Final fit out..

    Decided to make a proper floor/seat arrangement rather than butcher the sleeping mat

    Sit on top kayak seat for comfort, although this almost doubles the total weight!

    40L dry bag, approx. 550mmx 350mm x 150mm

    Weight approx. double that of the Mk1, however this includes the heavy kayak seat. Add another 1kg or so for the paddle
