OK I had my hopes built up a little there with talk of 10 years warranty but I guess that's only for deterioration of the fabric and this looks like a glue problem .
I'd imagine if I started I could pull apart a lot more seams & I've already said (to the club) that this boat has a limited life and anything we do will be a "sticking Plaster" repair

Ribraff how do you think a manufacturer would approach being contacted several years out of warranty with a problem like this?
As I said they are a respected builder
No one within the club is realy complaining but the general feeling is these boats are sh1t and the club shouldn't buy another
Would it be reasonable to ask for a discounted retube?
I don't want to go to the builder with unreasonable expectations but I do think this problem stems from some deficit in the build process (is that a fair assumption?)

You might find those tubes are polyurethane.

For comparison I had a boat by the same manufacturer and same material as that dating to 1998 on her original tubes and despite a lot of use they were like new - no patches - no delamination, etc. She is still 'as new' now with her new owner

Possibly a bad batch of glue?

I did wonder if they weren't hypalon as they feel different to the ribcrafts and my own boats
I didn't realise the manufacturer actually offered pu tubes?
If you've identified the boat please don't mention the builder as I didn't start the thread to point fingers I was just looking for opinions
At the end of the day it's a club boat that gets well used and little love and wasn't paid for out of one man's pocket.
I'm surprised the club ordered a pu boat but you don't know what the committee at the time was thinking maybe they thought buy it cheap and replace it in a few years which used to be the norm. The club finances are not what they were and boats need to be kept longer . A new engine was fitted to 1 boat this year so maybe this boat will be top of the list for replacement or retube next winter

It's always a good idea to speak to the manufacturer in the first instance, they may be sympathetic to your needs.

The tube appears to be constructed from elastomer (CSM/CR), probably Pennel & Flipo origin.

The 10 year warranty being quoted typically only covers the fabric. The glued surfaces are usually treated under a shorter manufacturer's warranty. Not to mention, the 10 year warranty is almost always pro-rata.

The failure mode pictured is a "cohesive failure". In short, the adhesive did not stick to itself properly.

Possibly causes
1.) Age / oxidization (probably a huge factor here)
2.) Too dry before layup
3.) Too much humidity (Which causes #2)
4.) Bad glue batch

Wow thats terrible on a boats that not that old

When I bought my bought (Zodiac) it came with warnings not to use any cleaners with any silicon in them. With many fibreglass boat cleaners having silicon Ive had to buy special inflatable boat cleaners and UV protecting sprays.

The boat looks like water is beading on the surface like it would from waxing or silicon.

So could any of the damage be from using the wrong cleaners, does silicon in cleaners actually do any harm.

Silicone won't harm Hypalon, but it makes any material difficult to glue

out of interest dave how far does silicon penitrate into the hypalon reason i ask is that you have to give a good abrasion to it before gluing does it go deeper that that?

My hypothesis:
It soaks in through the topcoating (CSM) and saturates the internal cloth support of the material, then wicks along the entirety of the panel.

With heating, cooling, and surface pressure changes, it flows in and out through the pores and can potentially get behind a glued surface and destroy it.

Reasoning:
Water does the same thing already. Through an unprotected edge, the internal cloth wicks water and microbes/fungus, which can lead to a mildew bloom (spotting) in the coating.
