I had a bunch of spectators on the boat so they saw the general vicinity of the crash.
My advice is; if you know you are going in the water, make many mental notes of where you crash. It can all look the same after a panic situation.
I had the best case scenario crash. I had visual observers that noted the crash site and I had the getterback ziptied to my UAV. It deployed in under 10 minutes. My UAV insurance requires the drone. So I was happy that I was able to recover. I will be purchasing for all my UAVs.
