What is foiling?
Adding value for the sport and fans.
Nowadays, the spectacular performance of the foiling multihulls is thrilling an even larger public. The impressive increase in speed was a quantum leap in the history of competitive sailing. However, the instability that comes with foiling is also clearly visible. In order to maintain foiling for as long as possible, the sailors on board must put in a huge physical effort. At the same time, foiling also requires a wealth of experience and tactical nous.
The use of hydrofoils and the resulting ‘flight’ of the yachts has revolutionised the sport. The graphic display makes this foiling time accessible to fans and TV viewers. Seeing the current value on the screen allows them to immediately recognise which crew has the upper hand. The formula is a simple one: whoever flies for the longest is the quickest. Whoever is the quickest wins. BMW FlyTimeTM will also help clarify who is leading the race at the finale of the 2017 America’s Cup.
pushing the team forward.
“If you’re not foiling, you’re not in the race”.
James Spithill’s team fights hard to remain ‘airborne’ above the water for as long as possible in every turn. When the boat rises out of the water and glides on just its hydrofoils, it can achieve speeds of up to 40 knots – resulting in something of a balancing act. “Sailing multihulls is a challenge in itself. It is very, very difficult for the team to race when it is not sure what the opposing boat is planning. The best form of practice is to race.”
After the race, the real-time data collected by the team using the very latest in sensor technology is analysed. This helps to optimise the foiling in the next race.
Inspired by the BMW 7 Series.
The Portsmouth round of the LVACWS marked the first time that BMW FlyTimeTM enhanced the onscreen coverage with important information. Based on the design of the head-up display used in the BMW 7 Series models, it illustrates which boats have the greater chance of taking victory.
Sophisticated sensor technology is one of the major strengths of the new BMW 7 Series. It boasts such driver aid systems as the steering and lane control assistant, remote parking, and BMW Night Vision with Dynamic light spot.
Real-time data encourages innovation.
The ORACLE TEAM USA multihulls are equipped with the very latest in sensor technology. Sensors on all important components gain sensitive data during manoeuvres out on the water. A transmitter sends these straight to the developers back on land. This makes the real forces visible and is followed by a direct comparison of real-time data and existing computer models. The findings ultimately help the team to achieve a longer foiling time in the next race.
As well as being of great use to the teams, the real-time data obviously also enhances the experience for spectators. They are able to see which yacht is foiling best at any point in the race.
Between DTM and sailing.
Data shows the way forward.
Sensor technology drives innovation in both sailing and motorsport. Many gigabytes of data are collected during a race – whether at a regatta or in a racing series like the DTM. The developers then face the challenging task of filtering the huge volume of data for valuable information, which allows innovation and thus improves performance. This applies in both competitive sailing and motorsport.> BMW Motorsport
