Well facts known to me are two Zodiac 340 air floor models around 2000-2002 on Ebay this year... one with transom detaching and another with a ghastly DIY repair for same issue.
In the past too a Futura owner has discussed his failing seams on here with me.
But the actual example closest to me is my own 1998 Aerotec which has both been patched and seam repaired in the past and I've recently run a thread showing some of the repairs I had to make to get it sound for our Scottish holiday...
Aerotec patching/glue advice.
At a quick glance the initial repairs in that thread are all patch and not seam related but posts 31,31,34,36 & 38 relate to failed glue.
The tubes themselves of course are all welded so they will last a "lifetime".
I've actually enjoyed using this boat to prove strong repairs can be made with (meticulous) DIY methods... I'd expect the repairs I've made will have a 10yr+ life. If an owner didn't feel able to do this work though the cost at a RIB/SIB place would be prohibitive I'd guess.
Office888 helpfully explained which bits of various Zodiacs were glued in posts 11, 15 & 18 on this thread...
Life expectancy of SIB?
