Most of my drone work is over water. I've splashed two drones in five years of flying; it happens. I'm flying a P3P and have been and am happy with the results. I don't have many of the features in later models so flying off boats gets very nerve wracking as you are trying to capture from a moving boat. If you can launch and recover from an anchored or stationary boat, that is always best. I splashed my most recent P3P in March as I launched off a moving boat and one of the props clipped the boat's antenna and knocked off a hunk of prop. From that point, recovery was futile and I watched helplessly as it flew wildly with little control from me until it ascended about 100' erratically, and then the engines shut down and it fill like a stone into the shipping channel and sank. ugh. Overall, flying over water pretty easy and more so than flying blindly over land where trees and other obstacles can come up on you without seeing them as are focused down on the water. Most of my work involves crew racing and training. The drone is tremendously helpful as a coaching tool. If you crash on land, you have a chance to recover the drone. Not so on water. The first crash I managed to recover but after being submerged in salt water, I didn't trust the drone. I put new engines on it and I did get it back in the air, but the risk of surprises was too great to risk dropping it on a crew team so that drone was retired. The second one is in Davy Jones' locker. The third P3P is good but I'm a lot more careful about launching from land whenever possible.
