Italy's Luna Rossa Prada Pirelli and Britain's INEOS Britannia are dominant in the semifinals of the Louis Vuitton Cup, both leading their series 4-0 against NYYC American Magic and Switzerland's Alinghi, respectively. The weekend races were marked by challenging wind conditions, which significantly impacted performance, forcing teams to adapt their strategies. Luna Rossa secured narrow victories, including a dramatic two-second win in one race, while INEOS Britannia showcased their strength with wins of over two minutes in one race. With another win, both teams would qualify for the final on September 26, where they would face the defending champions, Team Emirates New Zealand. Meanwhile, American Magic is struggling, compounded by the absence of their helmsman due to injury, reflecting the unpredictable nature of the sport. As the semifinals progress, both teams emphasize the importance of strategic maneuvering and maintaining speed to secure their final spots.
