Damaged Tubes- Help Please!

So after moving the RIB to its new home at Gillingham Marina today and scrubbing the hull to remove most of the mess we can now start our (hopefully not to lengthly) refurb process.

I've taken some pictures of all parts of the tube, we would really appreciate if anyone is able to advise us whether we can get this fixed easily, as we are (probably rightly) worried this could be an expensive job. Do we need a full re-tube (I hope not), but if so, what would this cost for a 5m Humber Assult?

Do they still hold air?

If they do then I think they can probably be made to last a while longer. Tube repair is all about preparation. Search for threads on cleaning tubes, repairing seams that are lifting and sticking on trim thats pealing off etc.

Replacement tubes if needed, will depend on various things like spec (there are various "commercial" spec 'wear' patches on there), who removes the old ones and preps the hull for the replacement etc. I wouldn't have thought you'd get much change out of 4k though, and it could be more, although I could be completely wrong.

There is definitely a puncture on the port bow, we have patched that and although not perfect it does release air very slowly (we used one of those quick patches, so I presume we can use something more permanent and get a better result).

If we're looking at 4k it would be cheaper for us to sell the engine and hull and walk away, I thought even a full re-tube would only be approx 2k :-(

I haven't poured over the extremely comprehensive suite of photos there, but other than them being possibly the dirtiest set of tubes I've ever seen, they don't look as worn as many I HAVE seen. You need a couple of seam tapes replaced and a proper patch on the leak. The rubbing strake may be damaged, but again, cleaning and an insert may be all you need.

I'd suggest that you clean it first as best you can, then soap it down and see where the problems are.

Your prop is thoroughly stuffed and if you've been running it like that for long, you may have done damage to the leg.

Great that you posted pics with your question it makes things a lot easier. The material looks in reasonably good condition so providing there is no seam problems repairs should be fine providing you use the right glues (take a look at our website for hypalon two part glue). A retube will cost you around 600 per meter. If want a estimate on repairs just let me know.

Dirtiest tubes you've ever seen...lucky you didn't see it before we attacked it with the scrapers, when we took it out of the water for the first time it was much worse ;-)

Thank you Ribshop, I'll take a look, but at 600 per metre unfortunately a re-tube is not an option, we would unfortunately have to sell up :-(

Agreed, a few areas are a bit worn, but I can't see any thread bare on the hypalon. Therefore, by putting decent patches or thick rubber wear patches on areas of concern, then using a professional, trade experienced tube cleaner with proper chemicals etc then seal it all, they'll come up sweet for less than a grand.

Our tubes were stained badly over 3years with weed and barnacles and also sun faded on top. We put thick rubber straking on the rear 2/3 underside of the tubes, where its on the water, as humbers usually are to keep stable, 750 for a 6.3m. Then got the tops brought back to life with M501 bostick cleaner/thinner, 150, it takes a fine layer off like on a car when buffed, you lose a layer of lacquer, but it works and is fine if not done often. Then sealed them again to protect from elements.
