Onboard Britannia, firmly visible at the front of the bowsprit, is a B&G wind sensor. It provides the most accurate wind speed and angle data, vital information for any America's Cup race, where every shift of wind angle or drop in speed could decide who crosses the line first.
For further information the main INEOS TEAM UK support boat has a full B&G weather /sailing station for monitoring off-boat conditions and data, which includes WS730, WTP3, Halo Radar and Zeus 3S Chartplotter.
With the speeds at which Britannia and the other AC75’s are travelling, there is no longer such an opportunity to judge wind direction based on the intuition, shadows on the water, or from the feel of the wind on your face. It's all down to the data on the displays in front of the sailors: so it is imperative that it is highly accurate, reliable and fast.
