The hull/cushions look very similar to mine, so if I was to guess I'd say its Tornado.

I'm sure i'll be told im wrong

Kevlar is not as "hitech"as people think - some people do use it as stiffners/reinforcing in hulls etc etc

I agree with RIVA. Looks like a basic fit out Cobra.

It is a cobra I think as i seen it linked elsewhere.

Kevlar (or Aramid as its supposed to be called) is just a replacement for glass or carbon but with different properties. Its stronger and has a lower density than glass and carbon but does not have the stiffness of carbon. Its very good for resisting impacts which is why its often used for ballistic applications. Adam Younger's 6.5m demo RIB is made from Aramid. The main reason glass is used is because its cheap like the budgie.

The hull shape and tubes remind me very much of a ribtec. white hull and that blue on the tubes is very ribtec as well!

Not once it's encapsulated in resin. It delaminates easily on impact. It has good stretch resistance and tensile strength which makes for rigidity.

Which is why aluminium is the preffered choice for a really heavy duty rib hull.
