New venture ?

I remember coming out of Zeebrugge one evening my little girl with me.
She looked a bit alarmed and said ‘‘Daddy that ship seems to be coming towards us’’ I looked and it did look like it was on a course to collide with us and eventually hit us.
I tried to reassure her it was ok, but the ■■■■ thing was getting closer and closer, until the ferry boat seemed to change direction severely and leaned over a bit, a bit too close for my liking.
One (or both) certainly hadn’t seen each other, is it radar or human eye?
