I believe that this is the future of on-the-water coaching, even better than a Go-Pro camera mounted on the rowing shell (which distorts the image in order to achieve a wide angle perspective).
I believe it could even replace the need for multiple mono-hulled coach boats (one should be sufficient per school or rowing program) which are expensive to buy, expensive to maintain and which throw up heaps of wake, even at slow speed.

AFAIK you need to have a license to fly drones in public spaces nowadays – check your local regulations. And the only issue I see with Evan’s suggestion is how to instruct the athlete if you’re not beside them on the water. Remote earpiece coaching over radio?
