That air floor it's a non removable type, right. If small leak, try a small drop or thin line of cracy glue or it's equivalent, let dry. Is it just droplets or slight more water coming in ?
Ooops, sorry it's Crazy Glue, the instant glue that comes in a small tube container, available at most stores. The one part glue that comes with boat is just good for emergencies, much better is 2 part pvc glue. (glue and hardener mix) Have repaired many air and water small leaks with instant cracy glue. Don't worry, will not eat or harm sib fabric.
A patch must be adhered on a flat surface to seal properly, not over a seam which isn't flat enough. Preferably would be to peel air deck a bit where it matches agasint seam tube and re glue with 2 part glue. If wanting a fast near instant repair go for the crazy glue without peeling. Clean well surface, apply when completely dry.
Is it the actual inflatable floor thats leaking or the starboard tube. Seams are the hardest to fix. If you were to peal back the seam a little and attempt a repair the leak would just move along the seam to a weak spot - so this is pretty much a waste of time. If the leak is on the air floor then you will have a better chance of finding and fixing the problem, but it will take time. The simplest solution as mentioned above is to apply a small amount of superglue at the leak and retest. Another adhesive to use is a product called VLP, which is a liquid vinyl solution. This is a flexible adhesive which will stay flexible (long term solution), whereas superglue is rigid and will crack (short term solution).
