I helped sail/transport a 32' boat down the coast of Australia years back with a friend and a professional captain/boat-transporter, it took a few weeks and we got to know the captain pretty well. He told us one time he was transporting a boat and was pretty far off the coast when he saw red lights in the distance coming towards him extremely fast. Then all of a sudden there was a car-sized vehicle hovering in front of him over the ocean...it sat there for 30 seconds or so, then accelerated away and was over the horizon in less than 10-15 seconds. The guy was kind of out-there, but I swear he wasn't making it up.
