French challenger Areva was penalized by an America's Cup jury on Saturday for accepting photographs of a rival boat.

The French challenger saw its sail limit for the Louis Vuitton Cup reduced from 45 to 43 after the jury found Areva guilty of two rules violations for accepting photographs of rival boat Luna Rossa Challenge from a media photographer.

Areva called the incident "a gross error of judgment."

Competition rules prohibit competitors from "observing or capturing images of another competitors ACC yacht with the principal intent and purpose to gain design or performance information."
