Repairs on an older Saturn inflatable??

[sidecar53]

Well, I finally got to take the Saturn out for a day-long trial on the bay (Rondeau). It was kind of rough and the seat mount has pulled away from the tube (pontoon??). Upon closer inspection, the other mounts look suspect as well, like the heat is breaking down the glue that's holding them on. Any ideas on what method and glue I should use to fix them? Thanks for the read and any ideas you might have

How old is the Sib ? Need to fully remove both lateral patched seat holders, clean well both surfaces with MEK (metil/ethil/ketone) buy a 2 part PVC glue and follow gluing instructions. As the procedure is long to explain check YouTube videos on how it's done. If the seat holders are becoming unglued, expect for other parts to become so..

Happy Boating​

Thank you so much for your reply, Sea Rider. Not sure about how old it is- I bought it 2 months ago from a guy that says he had it for 5 or so years and he bought it used. I'm guessing probably 10-15 years. It was pretty rough when I took it out last week and both the boat and myself took a pretty good pounding (won't be doing that again).
I have the MEK and I'll send for the 2 part glue. I looked last week for videos, but I didn't find much of anything. I'm not afraid of the work as I'm retired and I'll probably only have this boat for a couple years before I replace it. I'm really liking having an inflatable for the convenience, though. Again- thanks a lot

You're welcome Sidecar 53,
The tube's fabric looks brittle due to its age. To fix the black stripes where the seats hooks on will need to remove both large side patches, the repair must be done under the black stripes.

A heat gun is used, but could end screwing the tube's fabric if with no experience. Other method is to use a plain middle size screwdriver, soak it in MEK and find its way in in small depth increments inside the the patch, priest's patience is needed.

Inflatables are jumpy nice boats specially at non flat water conditions, take it easy on the throttle or will end with back pains. Which size is that Saturn and which motor brand and HP is being powered with ?

Found a repair link : https://sailrite.wordpress.com/2012/11/13/repairing-a-pvc-or-hypalon-dinghy/ Check if there's a method to pull parts that are becoming unglued..

Thanks again for your help, Sea Rider. I'll definitely check out the link above. The Saturn is 12 feet long with a 6 hp Johnson Workhouse motor.

Congrats nice combo, what's the current transom condition, is it still well attached to the tubes or becoming unglued specially at the upper transom and adjacent side tubes ? Is the Saturn being inflated to its recommended working pressure with at least 3.0 PSI once floating ?

I have done a few repairs to where the transom connects to the side tubes for now (I'll do a better job this this fall and winter). I'm not sure how well the last owner did on pressure, but I'm going by the book
