Have you ever tried to climb a rope ladder on a moving ship?
Stereo vision is helpful on ships (and allmost everywhere else where you need eyes), even when not boarding.

Just a thought
But I know I am worse doing climbing etc. with one eye.
It is probably something you can train and get used to, that it is not such a big deal, but I cannot imagine doing it on the same level one eyed.
