Is it the join just at the end of the tube where the cone is on the end of the tube ?

Yes, there is still about 20mm attached before the edge of the main tube.
Is water likely to get in, or does the pressure keep it out?
Dont want to create a bigger problem...

If it's a forward facing seam, it's being dragged through the water with water pressure building in the loose flap. Think about what forces are involved, and what the result will be should the leaky flap fail completely. Then make your own call as to proceed or not.

It might hold, but might not if its the cone seam, Ive had one that failed and filled the entire port tube with sea water whilst under way, if your a good bit off shore, thats going to give you a big problem, depending on how your boat is rigged with flotation else where.

If the other side is looking poor too, I'd be cautious of any adventure, as you dont know what the weather will do. Not perhaps what you wanted to hear, but , if the glue is weak, you just dont know when the whole seam will fail completely. Many hulls will still run ok after tube deflation, but like I said, it depends on how your boat is rigged as to its performance in this state, and the weather attacking you.

In my situation, I had a leak at a seam on the bow a few days earlier which I repaired .. the port sponson leaked quietly on its own unbeknown to me whilst under way .. but as is often the case, if one seam is beginning to show signs of wear, others will do too

Probably wise advice there from Bigmuz but:

(1) It sounds from your original post that it is a very slow leak? Many people go to sea with tubes which go limp within 24 hours. If they go limp within 1-2 hours that is a bit more serious.
(2) It depends where you are planning to go. There's a big difference between getting a blown tube 10 miles from shore, and a mile off a beach.
(3) If your boat has 5 tube sections then even if both the rear ones go you should be fine - although it won't make for a relaxing trip!
(4) If you are not confident that the baffles between tube sections are sound don't go a failure in the rear will quickly become flat everywhere.

Assuming the idea is to stop it worsening during use would some duck tape over the join serve as temporary protection to stop further erosion ?

I have been fighting one of these since i got the boat. Small leak on the underside of the stbd rear section.

In the absence of a reliable patch (never under estimate the force that 20+knots of water can exert) even after trying to build a leading edge with excess glue i have found the best solution so far is to keep the pump handy & use it as required.
