Those white things are sails. They bend the wind, creating a lift force that reacts with the lift force of the water over the keel, making a net resultant force that moves the boat though the big blue wet thing.
The picture is all distorted by the gravitational waves affected by our extraordinary velocity. And the image-stitching software. You can also see our cool new phiphertex window shade cover over the saloon windows.
This is (half of) our asymetric spinnaker. It will be terrifying to fly if it’s actually windy.
