Eye in the Sky

Yesterday afternoon this chopper flew very low over the Port America's Cup for the better part of an hour, including directly overhead of Challengers' ACC yachts. Does anyone know to whom this heli belongs? Or who was in it and what they were doing? Only Challengers were out sailing yesterday. Note the camera pod or pods on the underbody. The Challenger Commission chair, Alessandra Pandarese, has asked ACM to investigate.
