Would it be such a big deal to put it on a trailer and tow it to the UK? Then you can get it done by one of the best - UK seems to be the centre of the RIB universe as far as excellence goes. I think that's what I would do in your position - I would have done the same but it would have been £5000 to freight mine to the UK and back which was a bit too much!
Or they may be able to supply a re-tubing kit with instructions if you fancy doing it yourself (I didn't) - assuming they have a template for that boat. If they don't, your other option is to cut the old tubes off, post them away to one of the re-tubing companies like Henshaws or Paul Tilley and they can use the old ones for a template I think.
A Boat is a hole in the water, surrounded by fibreglass, into which you throw money...
