The first time I filmed this ferry I didn’t have a tripod with me but this time I did. The visibility wasn’t as clear but still good so we can see details on the ferry like the two funnels/chimneys .

I also made this video at 30x speed where I centered the footage youtu.be/T3jus582qGc

Date of footage: 19th March 2019

The ferry is sailing between Rønne and Ystad, marinetraffic.com/en/ais/home/centerx:14.4/centery:55.2/zoom:9
