I tore a hole in my inflatable dingy that is about a foot long. Are
there any repair kits on the market that allow repair of a wound this
significant? Thx for the help... John

I don't know if I'd bother with those special purpose, ie. expensive,
inflatable repair glues. The latest repair I did on my PVC Bombard used
3M 4200 and the patch is stuck on fine. Previous attempts with the
special glues were less successful even though I followed the
directions, primed the surfaces, etc.
If it were my boat I'd coat a large patch with 4200, slip it inside the
deflated boat and position it to cover the slit. Weight the boat down
with books or whatever to make it lie flat and leave it for a week.
Then coat a small patch with 4200 and place it on the outside to cover
the slight. Probably end up being the strongest part of the boat.

Given the choice between 4200 and a glue designed for the material that your
dinghy is made of, go with the specific glue. And get the 2 part glue. I
find it holds better than the 1 part.
