I finished my third packraft a couple of weeks ago. This time it was an Ultralight.
Matt, you wrote this is the easiest, but for me it was more difficult than the others. The fabric is so thin, that I was afraid I will damage it just from looking at it. I was very carefully and quite slow. In the last hour, when I finished the last bit of the rear seam I did one final mistake. I put my hot air gun for a split second near the fabric and burned a hole in it :-(. But fortunately, I could fix this quite easily.
I sealed all seams with a double layer of Aquaseal. Have not a tiny leak so far!
Again, it was a great project! Your instructions are absolutely awesome. Never have seen something that detailed.
And here one picture of my packraft fleet. Only the Skeena is missing. Will build that too.
