I absolutely would not use expanding foam.

Well of course it's true. The question is whether it would be an improvement or not. I suspect it would not.

Best bet would be to call in a professional (if you're not up to tackling it yourself.) Plenty of inflatable boat shops there (not so much in the US); shouldn't be too hard to get at least an estimate.

Suerly once its pumped up,just spray some soapy water over it ,eliminating each section untill you find the puncture bubbling up.

Yep,
You definitely can fill them up with foam. It's a trick that works well with totally knackered tubes that are beyond viable financial repair or so badly damaged that it's not worth the time.
Whack some foam in and you have a boat with a couple more years of life left in. Don't use them in swell though they snap! I know from experience.
Get the tube filler. I think there's a thread on here somewhere about specific maritime grade stuff, not unlike innertube liquid called "Slime".
Don't do the foam thing!!!!!

foam filled

I just bought a rib that the owner tried to fill with expending foam. Well he did not try , he did fill them and it expanded to the point it pulled the longitudinal seams apart. Not a bright idea from what I can see. Although there must be a correct amount at which it would work.

I see your point, but there are advantages to foam collars: solid fendering, no punctures on sharp stuff, and buoyancy to boot. But they're not made by filling an inflatable with foam...

I agree with the advice you're getting above about expanding foam, and I don't think it would do any good in your circumstances either - you wouldn't have cured your leak, so you'd end up with a tube filled with waterlogged foam.

Fix the leak, that's the answer
