There's nothing wrong with greys. Any fools can get blacks and whites, that's just a question of sliding the sliders around, or picking a sufficiently high grade of paper if you're printing wet.
It's getting the middle tones right that's tough.
What appears to be going on here is that everything in play is quite small. The boat, the clouds, the details in the hills. These are all tiny features, and they're either not in focus, or the small aperture together with lots and lots of air is making them soft. Regardless, you have a very soft image here, with relatively sharp water in the foreground. Attempts to ratchet up the drama by making a bunch of randomly selected crap be black and another bunch of randomly selected crap be white is going to be a lose.
I would leave the greys alone or possibly add a little contrast to the higher midtones, but lightly, and burn lightly everywhere around the ferry to emphasize the that point, and then add drama to the ferry itself with some careful burning and dodging.
Basically this isn't going to be much of anything unless you can get some detail in the ferry, which isn't there. It's just a blob.
