@ DrLightWind :
Since 2002, European law has provided for an unregistered design right. This is a form of protection for designs that automatically comes into existence once the design has been put on the market, or otherwise disclosed to the public, in the European Community. As it is an unregistered right, there is no need to apply for protection. However, as the term of protection is only three years, it is best suited for the protection of products having short life cycles.

So Taaroa is protected by default inside the E.U. if Mango's wings design is too close from Taaroa's one, he could be in trouble.
@ Mango:
there is still something missing ... where are the informations on the Tbar (mast & fuselage)?!!
Last time I checked, they are still needed to make an hydrofoil!
