Fuel tanks are portable plastic jobbies under the bench seat so not prone to getting wet/corroded.
It seems from replies so far that it's a bit of a common problem, not something to be too concerned about (its not like you can sink a RIB that easily!).
And yes, I have checked the joins/seams between hull and tubes....
It must just materialise in there all by itself!

The only time I got gallons of water in the bilge was when I stuffed a wave and the deck water drained in to the bilge from a deck fitting. Do you have any leaking deck fittings?

I suspect it's a combination of deck fittings, through hull fittings, bungs, tears of joy from the lucky owners, etc.

Out of interest, the ONLY rib we have that NEVER has any water in the bilges is a 5.5m Tornado. That actually has the opposit in as much as when you take the bung out it lets out a small amount of pressurised air!!!! You might guess what it's nickname is!
My Osprey doesn't take in any water into the bilge, so now I am think that there must be a lip (depth) from the brass bung to the bilge floor - is there? Because if there is I'll need to lift my nose up more at after each outing.

Had my Vipermax for 5 years, never had water in the bilges....Not Ever! I used to check but haven't for over a year. I think I'll check after writing this

What about the joint between the console and the hull?

I chased a similar leak for ages and it turned out to be spray / rain creeping between the console and the floor and thence into the holes for wiring / steering cables in the console.

One common problem is that water will run down the cables coming out from the witches hat screwed down at stern to feed into the engine. I use self amalgamating tape to help prevent this, you will be surprised how much water runs down there.

No water in our XS RIB, though I still check the bung occasionally.

The Atlantic 21 leaked quite regularly though I think they sorted that now.
