Repairing Baffles?

Bought a very cheap Zodiac MKII C and have found that the baffles are all gone (all three chambers are running into each other). I knew it needed work but did not realise that the baffles were all gone. Fixed all the other issues pretty easily and holds air fine but a bit risky to use IMHO without another 'safety boat'. I don't think the seller knew they were gone and it was cheap so not too bothered but its too good to bin.

Have been told its a nightmare job to repair them, anyone got any tips? Was thinking of putting a camera inside to assess the damage then cutting hand sized holes to allow repair - ideally in the bow section to reduce consequence of patch failure.

Anyway look forward to some tips, as I say too good to bin!

Try the in-tube liners as they provide a second defence, can't remember off the top of my head what they are called but thet are effectively inner tubes that you introduce into the existing tubes.

The only people I am aware of selling them for permanent use were Gemini. A good search of the forum would be recommended before anyone handed money to Gemini (not this is NOT Gemini the S.A. boat builder - but a small UK outfit making PVC tubes etc). Last time someone was complaining about Gemini he claimed to have stopped trading although I did see adverts in RIB international sometime after that though.

Henshaws (trade member on here with username Christopher) does now sell "emergency inner tubes" Emergency bladder - Henshaw Inflatables Ltd not sure how long he would advise they could be used for.

depends on how much of the baffle is blown, there are way more qualified tube repairers on here than myself, but I understood that to do it properly the semas have to be taken apart, and that cost wise, this dismantling of the tubes was not that much different in price to a retube, that would give you brand new tubes - a significant rise in value of your boat....worth asking Ribraff on here.

PVC and blown baffles?

To clarify to those who replied, it's a sib.

Could be I am calling them the wrong thing, maybe they are called bulkheads, it is the inner chamber partitions that keeps the tubes separate (for safety).
I am hoping that they have maybe only lifted a small bit and can be restuck or patched internally.

(Was not from eBay, bought from here but I paid my money and took my chance so not dissing the seller and it was cheap enough to take a chance on.)

No worries, I asked because I went to Winchester last week to buy one from Ebay and the baffles were all blown through so I walked away. If it'd been the same guy, he said he'd bin it.

Probably not worth repairing in my opinion. I have the same SIB (with aluminium floor boards). My one is 1986 (seams on top under rope lace cuff and row locks). There will be a bow chamber, two sponson chambers and the inflatable keel. If you cut a hand sized hole near each chamber - that's a big repair, and will need a big patch, etc.

Previous owner probably blew them by not getting air pressure equal before finally inflating to final operating pressure. The internal baffles are normally okay on these boats. It's the seams and end cones that tend to go.
