		You can use a gauge to measure the pressure.  I used one of these with my FatCat and use it now with my Outlaw Rampage:

As for your FatCat going flaccid, haven't you ever watched Seinfeld? What you have experienced is SHRINKAGE, my man. When your rigid, proud float tube hits that cold water, the air inside shrinks, and the pressure goes down. Just like George, when he was in the pool.
Pump it up a little more after the pressure goes down. Also remember to let some out if it sits on shore in the sun.
