I agree with Tomas, you have one of the best use cases I've read, good choice.No, no videos yet. The boat is currently laid up for repair following Hurricane Irma and we've moved off and into a temporary apartment. We were in the Florida Keys (Marathon, FL) when the hurricane came through and the boat was tossed into a pile of 5 other boats in the mangroves when the mooring cable failed. We have been talking about getting a drone to document our sailing trips and I decided to make use of time ashore (another 6 months or so) to get the drone and fly it.
I just tested the camera for stills and video last week. Nothing to my mind which so presentable so far, but at least I know it works!
Sorry to hear about your boat. The misses and I were booked to visit the Keys in April, but with the hurricane damage we decided to postpone that for another year. I was there in 2010 with my son and had a great time scuba diving and taking in the scenery, including the miniature dear, native to one of the islands. I wish I had my Mavic back then, perfect for capturing animals, less noisy.
