Found these today. Might be interesting for people, or they may already have been posted..
The DIY packraft site is wonderfully inspiring. I know that one of our members made one a year or so ago, and I was amazed at the outcome, but that post sort of fizzled. Maybe this will inspire some.
I have 2 original Alpacka rafts from 15yrs ago or so, and have had a lot of fun with them, but would love to extend the tail of each to add some tipping over backwards stability, and, having looked at this site, I can now see these modifications of mine as a doable project...it also puts packrafts in reach financially, if you are prepared to make your own.https://www.diypackraft.com/shop/
This next site is a bit more obtuse. Some very light cuben/dyneema kayaks, and other stuffhttp://www.cubenmaker.com/?1
I’ve struggled to be inspired about any projects over the last 7 months, but am planning to make a new spray deck for my sea kayak this weekend, and to actually have a paddle in my kayak. In contemplating designs, I found these sites, and I hope some of you will find inspiration .
