Sorry Mike ,but your "Big Brother" paranoia is not warranted.
The fact that the Hobie comp-tip was the result of a negotiated settlement of a lawsuit is well established.
Of course Hobie Corp, in their infinite marketing wisdom, describes the damn thing as a performance enhancement.

There was a similar (operator error) lawsuit against Nacra.
They chose to fight it and won.


About the original question.

You might be able to take a piece of a broken carbon mast, that matched the section, and make a comp-tip out of it.
