A little footage from 65 feet above Shearwater.
Shearwater has an extremely powerful rotating mast, acting like an airplane wing. It constantly, autonomously, searches for the wind and rotates to head into it.....no matter the independant heading of the boat.
In effect, it organizes and thus harnesses the maximum power of the wind at any given time - leaving one either sailing magnificently or hanging on for life.
In a big blow...the challenge becomes what do with this permanent sail that one cant take down.
