The same methode is used in intercontinental missiles and various other applications.

It is definately a smart thing to do, although I'm not sure about the patent though. As this idea has been used in various other applications is stands to reason that it is not new technology any more. Also its application in boat design is not new. How about the RIB's ? Rigid inflatables boats. In effect the rubber tube around the polyester plaining surface is stiffned in the same way.

But you're definately thinking outside of the box.
