Works fine for us, more often than not the tubes are pumped and hit with your fist, when it bounces off tubes are hard enough.
Getting the pressure equal in either side isn't hard.

It seems that inflating the tubes is a personal choice to where one starts.
Due the the absence of directions in a manual.

Me I always started from the middle. Blew all the tubes up in part then topped them all off with extra air when i got my breath back from hand pumping like and idiot.

Thanks Guys,

Our last boat had an inflation order in the manual of rears first working way up both sides to the front (as per jwalker), so I have stuck to that.

The Humber has pressure relief valves so less worried about over inflating.

Thanks for the advice on the drain - I would never have thought of that!

I definately enjoyed the pints more than I would have reading a manual!

It also allows a bit of deflation of any section whilst keeping all the pressures the same because the cones can move to compensate.
I've always struggled to get pressures more or less equal. That seems the logical way to do it. I think you might have solved the problem.
