It depends on how much has come away.

Water will find its way in the smallest gap and travel along until it can find its way in.

Pictures would help get advice on this

I've had a similar problem on a Polaris RIB (aluminum hull, so not exactly the same.)

In my case, there is a heavy flap glued to the tube, and a hypalon strip bonds that strip to the hull. It's the strip that came unglued.

Not a really big deal to reglue, but you'd need to find out prep for the fiberglass. In my case, I prepped the hypalon as usual; etched and anodized the aluminum, and glued it back up with hypalon adhesive.

Just check to see what material your toobs are, my old 1996 valiant was PVC which will need different glue and different prep.

thaks for your reply's
is it just the strip of material that holds the tubes to the hull or is the strip covering something else.
I can get my fingers in and run them along the unglued section for about 2 feet,

If you've got 2 feet loose, you can take a peek with a flashlight. Most likely it's just the strip glued to the hull.

I had a valiant 490 and used that 2 part glue by polymarine to re stick a wear patch that kept peeling back . Despite following advice using plenty of acetone to key the tube i never realy got what felt like a good bond , and the patch peeled off again .
I then used the rest of the glue on a very tired old narwhale and was never happy with the bond on that iether , the material on that apeared similar to the valiant .
Lots of vigorous cleaning with acetone was the answer , maybe the surface of the old pvc had gone a bit hard or something
recently i finished up the glue repairing the bladder to a ringo and it worked but gave a high build .
I also used a tube single of single part pvc adhesive on the ringo from an old boat repair kit , it was clear and seemed to give a better bond by melting into the pvc rather than sticking on top of it . Not sure where that came from it smelled like styrene cement and i felt it did a better job.
