I9s detection and repair of internal air leak

I have an i9s that has a leak in the center floor air chamber. It is leaking internally. How do I detect where the leak is and is this repairable? Thanks

You have posted this in a catamaran section. The inflatable section has many old discussions in diagnosing and fixing floor leaks. Check the valves and exposed seams with soapy water. They are easier to work with than hidden seams which the floors have a lot of. There are good online sources on youtube for fixing such things, since the inflato forum here is kind of quiet.
