I finished my V3 raft about a week ago, and have been chasing down leaks! The build went pretty well, I’m now much more curious about commercial welding techniques. I did have some issues with the fabric contracting upon sealing, really only noticiable over the length of the two long red center tube sections. Once welded, the ends came up about 2cm short.. I suspect my iron was too hot? nothing some trapezoidal seam strips cant solve!
Heres some pictures of it (140cm) next to an older alpaca yak, and some weird little ice features.
If the water temperature is higher than the air temperature, does the boat pressure increase upon getting on the water?
