Ships, in front and on and beyond the horizon

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

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