Water is the most photogenic and the most unforgiving surface to fly over. A drone that loses power over land usually lands hard but recoverable; over water, it is gone. Coastal shots also bring specific hazards that inland flying does not: reflective surfaces that confuse downward sensors, salt spray, sudden gusts, and birds defending territory. None of this means you should avoid water, but it does mean you need a water-specific routine.

This guide covers the checks and settings that matter over water, from return-to-home altitude to the moment you decide not to fly at all.
