Oracle’s boat has hundreds of sensors embedded throughout its hulls, in the underwater fins and up the length of the mast. They’re connected by wire to a server in a waterproof box in one of the hulls. The server uses a single wireless access point to distribute data to computerized “wrist watches” and other devices worn by the crew. The others teams in the race are expected to employ a similar set-up.
The computer tells the crews the optimal moment to tack or jibe, or when to trim the sails to increase their speed. It does this by looking at measurements including the “bend, twist and rake” of the mast, which helps it to calculate the “true” wind from the apparent wind experienced on the moving boat.
