Hello, greetings from a Finnish sailor and DJI pilot (formerly
Phantom 4, now
M2P). A favorite location of mine in the greater Stockholm area is Vaxholm, reachable from Stockholm by local buses. The town itself is charming and so is the Castle (spelled Vaxholm Kastellet). I don't know if the sea is open or how much snow there is at this time of the year. We have lots of snow and frozen seas at almost the same latitude (60N).
Note however that you should consult your Swedish friends about drone laws in Sweden. I remember reading (last year I believe) that drones are classified as surveillance cameras and are either banned or require a permit. In last summer I was flying my
Phantom 4 around the Castle when an arrogant motor yacht owner threatened me with violence unless I turn off video recording immediately and pack my drone.
