I was thinking it would be nice to be able to take photo's and video of whales etc when we see them that include our boat in the shot.

The new (to me) "drones"or "quadcopters" would be an ideal platform to attach my GoPro to for this purpose and I am aware of models that incorporate video cameras.

I'm not really asking about the drones themselves but about keeping them afloat if for some reason they happen to land in the water.

Some of the models have a 'return to home' feature that uses an inbuilt GPS to return the drone to its launch position and go into a hover, but in the case of a boat of a boat, unless your in a marina it is very unlikely that you will be in the same place you launched it.

I guess that if you learn to fly it properly you should be able to guide it back to your deck or cockpit without incident but im a bit concerned that sooner or later it will end up having a swim.

I have tried to look for flotation kits for these things without a great deal of success.

Any ideas or info ??????
