Who has the oldest Hypalon tubes?

There has been much debate about how long Hypalon and PVC tubes last, so I'm keen to find out who has the oldest tubes in both Hypalon and PVC.

Also, when does a RIB typically need re-tubing? Is it 10 years, 15 years, 20 years or even longer?

I've got a Zodiac MkII CGT from 1986 (PVC). Seam went under rowlock and failed at cone ends. Repaired - but now languishes in a barn.

Depends on the material (its probably wrong to think of even Hypalon as just one thing as there are military/commercial grades, different colours, and some industrial applications have some much rubbing strip and wear patches it is almost double skinned!).

Indoor / outdoor storage.
Latitude / climate.
Covered / uncovered.
Frequency of Use (and inflation when not in use).
Type of use - divers sitting on/going over tubes, v's families on nice seats, v's towing dinghies, v's landing against barnacle encrusted walls.

Probably all contribute to the life.

However if I was "budgeting" for life I would assume:

PVC - ten years unless in very harsh environment.
Hypalon - twenty years unless in very harsh environment, and could be extended with TLC and care.

I'll add to this.

Based on average use by a non-commercial operator:
100% glued PVC, China origin : ~3-5 years from date of manufacture
Partial glued / thermobonded PVC, China origin : ~4-8 years from date of manufacture
Partial glued / thermobonded PVC, EU origin : 5-10 years from date of manufacture
99% thermobonded PVC, some Zodiac products only : 10+ years from date of purchase...no adhesive to fail. The only worry is UV degradation. Average I have seen is 15 years with moderate use north of 40 degrees latitude.

CSM/Hypalon/Neo :
>20 years, light use and/or north of 40 degrees latitude
15 years, moderate use or between 30-39 degrees latitude
10 years, moderate use south of 29 degrees latitude

My old Searider was build 1978 so it has got 38 year old tubes tht still hold the air fine.

I own a 1980 PVC eurovinil e2 which has welded seams. Tubes still look good

Thanks for this info.
In Poland tubes made from PVC are 2 times less expensive than hypalon (for example SPORTIS).
So if they last 2 times longer results be almost the same in term of expenses I think. Just in case asked this company for re-tube mine boat with hypalon - total cost be 3 000 GBP.

I still have a 1981 Zodiac Mark 1 GT I bought new that looks great, but time to re-glue the floor and r+r the transom seals as they are OEM. Best money I ever spent on a SIB.
Will be a Zodiac customer for life. This is her 1 year ago.

Cheers
