Re: ohhh no.. a hole!
I had a very small leak in my Zodiac this summer. I soaped all the seams three separate times and could not locate it. I had given up, after I hosed down the boat to remove the soapy residue, I lifted the boat on its side to drain the last bit of water, which is when we heard a whistle coming from the tube along the ground. Sure enough it was the leak! So, if you are having trouble locating the leak, apply pressure to the tubes, which can accomplished as we did, pushing by hand as you go along, or slightly overinflating the tubes. The leak was coming from the seam. I patched over the leak with a round PVC patch that extended a few inches beyond the leak and thought I was was done. Not so, it was still leaking! The problem was that the seam tape under the patch created a minute tunnel between the patch and tube through which the air was still able to escape (travelling along the tape and then out from under the edge of the patch. I thought I had prevented this by making sure I pressed the patch firmly enough along the tape line as I glued it down, but apparently I did not). I solved the problem by AquaSeal-ing over the spot the air was leaking out of edge of patch. Also be aware that sometimes with seam leaks the leak is not actually where the leak is detected along the tape, but the seam is leaking at another location and the air is running under the tape until it escapes.
