Water is never flat but is positioned in equilibrium with forces

Ships, in front and on and beyond the horizon

Is the horizon above, at or below eye level? (altimeter and LiDAR)

$Extreme variable refraction on Turning Torso$ $Ferry from Bornholmslinjen behind horizon, 30x stabilized, March 19th 2019 A 30x speed and stabilized version of my 2nd recording of a ferry disappearing bottom up while sailing away. The original footage can be seen here https://youtu.be/CkWaQrtGcjk Date of footage: 19th March 2019 Ferry: https://www.marinetraffic.com/en/ais/details/ships/shipid:155510/mmsi:219017081/imo:9501590/vessel:EXPRESS_1 https://da.wikipedia.org/wiki/Express_1 The ferry is sailing between Rønne and Ystad, https://www.marinetraffic.com/en/ais/home/centerx:14.4/centery:55.2/zoom:9 On a different day (19th of March) I used an app to get the position of the ferry. I made a collage with all the needed data to calculate amount obstructed here https://flic.kr/p/2dVCxfR Ferry height estimated based on photographs: 24m Observer height: 4.05m Distance: 21.6km Amount hidden geometrical on globe Earth: 16.3m Amount hidden including std. refraction on globe Earth: 12.9m Amount hidden observed: ~13.3m$
