Some of my friends have actually bought a few Inflatable Kayaks from Saturn. They did tested them in white water. They said that to repair inflatable kayak and its weight, compensate for the diffirence with a hard shell.

: Many inflatables are made specifically for whitewater use, and you probably
: needn't be overly concerned about punctures if you have one of those. The
: Saturn ones look like whitewater boats, for the most part.

: If you do get a hole, well, I suspect duct tape would work OK for a quick
: fix, as long as everything was dry. However, for real repair of PVC
: material, you might consult Tom Yost's website. He has complete
: instructions for how to make your own inflatable kayak (and many SOF
: kayaks, too) from PVC fabric. His gluing instructions would work equally
: well for kayak repair.

: Have fun!
