Another good idea, will do some measuring and I might go for that
though I do like the idea of the whole thing being removable in the event of any problems and also having a double layer of hypalon all the way down the aft chambers.
A seven chambered RIB would be verging on unsinkable, in fact I might even re-name it Titanic II. Then again maybe not...
I also thought of another idea which is that if you put relief valves (which I wish I had fitted) in the new sausages, and blow up the sausages first then the middle chambers and then the bow chamber, you would have some overpressure protection for the whole lot because the relief valves in the sausages would blow off at (say) 5psi and then the baffles would deform to reduce the pressure in the forward chambers.
Lots of options anyway, which is lots more options than I had a week ago
