@brucecampbell Hi Bruce,
The 210D fabric offered here is 8.25 oz (about 4 oz before coating). Doubled up, it would be much stronger than a painted 8 oz fabric because unlike paint, the TPU adds quite a bit of strength.
Seattle Fabrics offers a 430D heat sealable nylon, but it’s actually lighter than my 210D fabric, at 8.2 oz, which just goes…[Read more]

Any suggestions regarding heavier material or more abrasion resistant material for Skin on Frame (SOF) kayaks, canoes, or in my case a row boat? The heat sealing is most attractive and I could try ironing on a double bottom, but the bottom is the one the area least needing heat shrinkage. Most SOF builders use 8 oz. nylon or dacron, which is then…[Read more]

Several people have asked if it would be possible to make a self-bailing or inflatable floor using the double-layer floor option, and I have finished retrofitting my multi-colored packraft with an inflatable floor […]
-
I haven’t tried it yet, but it’s definitely on the list of things to do. I have an idea of how to approach it, but it will require a bit of trial and error, so please bear with me 🙂
-
Just curious, was the raft you retrofitted a single floor or a double floor before adding the inflatable floor?
-
It was a single floor. It’s not possible to heat seal to the back side of the fabric, so “windows” would have to be cut in the top layer of a double layer floor in order to attach the third inflatable layer.

Not yet. I think the R-value would be low because there’s no insulation and the air can convect freely… but it would be much better than sleeping on the ground!

Hey Matt, I’m about halfway into assembling my Telkwa kit, and everything is going smoothly so far. I’d like to make the raft self-bailing, and am curious on your thoughts.
I’m thinking I can make the Telkwa self-bailing by just adding four drain holes near the rear of the cockpit (using the two-way valves to plug the holes when in long stretches of calm water.
What are your thoughts on the necessity of adding an inflatable floor into the Telkwa? I’m thinking that with the seat being as large as it is, I can get away with not adding the floor, especially since bulk fabric ordering has been suspended for the time being!
I assume that the weight of the paddler is the biggest variable in determining how much water remains inside the raft when configured as a self-bailer, but having never sat in a DIY raft I’m unsure how deep my rear will be submerged below the water line (165 lb) so was curious about your experience.
-
I haven’t tested this myself, so I would start by adding one drain to the finished packraft and then paddle around with it open to see where the water level equilibrates. If it’s acceptable with the just the seat, add the other drains and go for it. If it fills up with too much water, then I’d start thinking about a separate inflatable floor insert. Cheers!
-
Thanks Matt, sound advice. I’ll post my results here for posterity after testing.

Yep, you can do that. I’m not sure if it makes it more stable, but I’ve done basically the same thing.

@awg28 Hi Andrew – yes, absolutely! It will not have to be fitted during assembly.

Hi Matt,
Would also like to see a spraydeck!
Do you think once you have done a design that it would be able to be retro fitted to your current designs?Andrew

Thanks for the review, @webermarcoweber – you are one of the few people who have experience with both the DIY Packraft fabrics and fabrics from ExtremTextil.
Your new fabric is in the mail 🙂

Hi @michael-s-morse,
I and a few others have experimented with fabric with TPU on both sides, but everyone has concluded that it is unsuitable because it is very difficult to heat seal – you can’t apply heat directly to it with a sealing iron because the iron melts the TPU, creating a sticky mess. You have to sandwich it between two layers of…[Read more]

I am currently sourcing fabric with TPU on one side and a thick, airtight PU coating on the other side, so stay tuned for that addition to the shop!

TPU Coating BOTH SIDES:
Has anybody found a source for TPU Coating on BOTH sides? Would be great to source this material in Nylon 66 and 200+ denier – especially to make a raft that will hold air better and last longer – perfect for a 2 person raft on whitewater.TPU Coating on Inside Build:
