In a RIB, yes. If you're not confident about this, then don't go far in your RIB -- a green wave getting into the boat with you will fill it up very quickly!
We had this in Phoenix, off Cape Wrath a few years ago. We didn't stuff the boat as such, a big steep wave just fell on us. It knocked the windscreen off, inflated a couple of lifejackets, and filled the boat to the top of the tubes. Time went very slowly while about 2 tons of water drained out through a couple of 2" scuppers, but it didn't really take all that long. Just kept into wind and steadily motored forward, although having the torque of a diesel probably helped at this stage.
All I could think of was Alan's parting advice as I left Dunstaffnage that morning: "You should be OK without an air filter, but try not to get too much water in the boat"!
As for filling a RIB with water making it less
stable, this is clearly not so -- load up a RIB and see if it wobbles more, or less. Never mind calculations and formulae for CoG, CoB, FSE, ABC, TCP or whatever!
