Yep, pretty common here too. One RIB got swamped so often on a swinging mooring the owner had everything moved up above the waterline - batteries, fuel connections, etc etc.
Our own RIB is in the inner harbour on a running mooring, we had so much rain the night before last I had to be careful getting on board as the water was slopping about something horrid.
(Bilge pump float switch is not currently at 100% efficiency)
The long and the short is that this guy's RIB may not have been left unattended for all that long. Flat batt, dodgy switch etc etc + lots of rain and some big winds.
