I was talking with a good friend of mine who helped us out with the Rib and he told me that he had gotten an extra lamination and a tungsten Transom to further reinforce his RC 5.85. Do these things acutaly help? or are they just a way to get a little extra $$$ for the company?
Maybe it's just me, but I think your friend is either full of it or has been told a good story! The best use for tungsten that I know of is in light bulbs!
Transoms (just like the rest of the boat) are rated for a certain horsepower - that means they are strong enough - why would it need to be stronger unless you're putting a bigger than rated engine on?
According to here The properties of tungsten would seem to eliminate its usefulness on a RIB
It is mainly used for hardening steel, making light bulbs or making tungsten carbide bits for drilling and machining. Its also used in several chemical processes and in the making of magnetrons (the things that produce microwaves in your ovens).
Its very heavy and brittle not the sort of properties that are usefull in a transom.
but moving on..what does the extra lamination do? heh..Sinks the boat?
