Nitrogen cylinders.

I was just thinking the same. Quicksilver 2.7 takes me about 5 or 6 minutes with a cheap unbranded foot pump, the Redstart about 4 minutes. Why would I use anything else?

I timed myself with a footpump. I inflated a 2.3m airdeck dinghy in between 4 and 5 minutes. Not trying hard: just gently pumping.

So why bother with anything morecomplicated?

For me, because a foot pump with largish inflatable on small boat was not easy. Used to useHalfords rechargeable inflator which was not good even after moss. Also when inflating the dinghy on shore was handy to be able to leave the inflator to do the bulk of the work, topping off with a foot inflator. It meant I could get on with something else.

Rechargeable wad good for me because of limited battery capacity.

I too considered pressurised cylinders but ruled them out.

A few years ago we bought a Coleman cordless one like this

and it's absolutely superb.

Yes you have to manually pump about 3-4 pumps max with the footpump to get it really firm, but it makes such short work of the main inflation that's no hardship at all.

Inflates a 2.4m dinghy in less than 5 minutes - about 2 mins per side.

One charge lasts years. Bought ours about 3 years ago at a show for £20 (on offer) and I'm still on the first charge!
Can recharge from either mains or 12v. Can be used to fast deflate the dinghy as well. Cordless, no wires to trip on. Weighs about 1-2 kg - probably about 1/10 as much as a pub cylinder. What's not to like!?

I use one of these, very quick to inflate. It has a deflate option as well.
 
I think some folk are either easily pleased or have beach toy inflatables. I bought the Coleman as suggested and a hair dryer would be more use.Might be ok for beach ball or lilo but not a real dinghy. Thats going straight back to the shop.

Maybe some folk are impossible to please ;) What are you inflating. I use one to pump up a 2.7m Seago and have no issues at all. Maybe you have a duff one!

That explains it then, a 40 year old inflatable made from whale skin:D

I did buy my coleman about four years ago, so maybe they aren't as good now as they use to be.

I take it you have checked for the obvious like holes, open valves, inflate rather than deflate :p

Anyway good luck with your search.

It's far simpler than that.

in my younger days if I was in a hurry, or just feeling lazy, I used to inflate our dinghy by cracking open the pillar valve on a diving tank a few inches away from the (Avon) dinghy valve.

The dinghy inflated in a few seconds, and the pressure was fine.

I'm pretty sure there was a venturi effect that helped it along, but it was pretty neat.

Almost 50 years ago I saw a demonstration by the SBS where they inflated a Gemini dinghy using compressed air and a venturi adaptor for the filling valve. This was apparently marine proof and avoided the danger of tying to over inflate the boat. I suspect they used a lot more air than was needed to fill the tubes but when you need your boat inflated NOW then \I suspect that doesn't matter
