Day two for the Louis Vuitton Cup semifinals. Recovering from the double success accrued on Saturday against NYYC American Magic (albeit with effort), yesterday Luna Rossa Prada Pirelli also won the third and fourth races against the Americans and moved to 4-0. The Italian crew dominated the first challenge, while they only managed to prevail by 2" in the very tight second race. All was easy for INEOS Britannia, now 4-0 up on Alinghi Red Bull Racing. Both Luna Rosa and INEOS Britannia are now one step away from the final: both will return to racing today in search of the match point.
