"Gybe" has a unique meaning and is proper English. "Jibe" has at least three and is American in its nautical sense.
While we're on the subject - It's "VULCAN" not "volcan" or "volcano"

And its "PLANING GYBE" not "power gybe" which is an archaic long board term for a rig steered gybe according to an apocryphal source

As for the "Flaka", Pedrick invented it adapting the "Taka" and called it a "Swayze".
"Flaka" may be a better name because it acknowledges its routes in a semi eponymous manner and also because it almost rhymes with "tack" and it is a tack wise rotation. However Patrick Swayze croaked a few months ago. Wouldn't it be a nice memorial gesture to revert to its original name? Could it happen? Will it happen? Or would you rather forget?
