I have used this foam extensively. It is expensive. It comes in
different densities. If you used the 8lb/ft3 the dinghy would be quite
heavy, albeit indestructable, in the order of 120 140 pounds or more.
foam less dense than this (4lb/ft3), if you dented it, there would be a
void between the hypalon and the foam. It also gets very very hot when
it hardens and you woul dhave to do more than one pour. Your working
time once it is mixed is around 45 seconds. You could probably do a
dinghy in about 8 or 10 pours. Of course the dinghy would have to be
vertical, with the hole you are filling from at the very top. I would
say don't try it. Get a hard dinghy. Isnt the point of inflatable
dinghys that they inflate, and deflate, so they can be stowed? A hard
inflatable dinghy would have to be the worst kind of dinghy ever since
it cant sail, cant be stowed, and would be really really heavy.

Hello All,
I have an old piece-of-cr_p inflatable (came with the boat) that leaks
air.
Has anybody ever tried to fill a dinghy's air tube with pour-in-place
closed cell foam?
My dinghy held air just fine until I deflated it and rolled it up for
winter storage. I'll never do that again...
