35th America's Cup on Foils-- Team France

Martin Fischer on why Team France has a different foil on each hull:

http://www.catsailingnews.com/2017/0...last-ac50.html

Excerpt:


The foils are made up of two elements.
The upper section of the appendage called the SHAFT
The lower section is called the TIP.
The junction between the two is called the elbow or knee.
The class rule imposes a maximum number of Shafts and Tips:

On the training boat, the team can build 6 Shafts and 12 Tips
On the AC Class, just 4 Shafts and 8 Tips are permitted.
The lower section, the Tip, must not represent more than 30% of the foil weight, but its length is not restricted.

"Groupama Team France, like its rivals, is adapting the foils according to the wind ranges and is building two types:

Foils for light to medium airs, whose Tip is longer
Foils with a shorter Tip, optimised for higher speeds

Martin Fischer: “The rule does not require the boat to be configured symmetrically when racing. As a result, our port and starboard foils can be different. This is an interesting element, because when you run the race simulations, you notice that the course is not symmetrical. There’s more emphasis on starboard tack than port tack. There are two high-speed reaching legs on starboard tack.”
...
