Thanks to Oracle sailor Ky Hurst for this video of four AC45x experimental catamarans testing on the Great Sound. There will be plenty of action on the Great Sound in 2016 and it will heat up even more in early 2017 when all six teams are training with their AC Class race boats.
In this short clip you can see Artemis Racing with the clear wing sailing right to left. The two Oracle Team USA boats move left to right, followed by SoftBank Team Japan.
