Hi... I am really really a newbie when it comes to drones. I would love some advice on flying over water. I am making a documentary this July where I will get to ride on the El Galeon, a 170 ft Tall Ship from the Cleveland area to Bay City, Michigan. I will be spending 4 days on board the ship on Lake Erie and Lake Huron. I purchased a Phanton 4 and I have been practicing daily learning to fly it and I am getting a bit more comfortable flying it, but I still am a nerveous wreck while flying. I am sure that by July I will be confortable enough to get some amazing footage out on the water. I would appreciate any and all advice from experienced flyers who could share any tips with me. I have been reading about turning off the Vision Positioning System (VPS) while flying over the water. Is that a good idea and if I fly without it what precautions do I have to take. Thanks in advance to anyone who share their wisdom with this newbie.
