I had them on a previous boat and found them very effective. Can be hard to fit as mentioned before. Added bonus: they offer a degree of protection when you bang your shin on the top of the winch!
I use the same type monocular as JumbleDuck's recommendation and had no problems adapting to using it instead of my old bins. In fact I found the monocular easier to use - you don't have to fiddle around setting the width to match your pupillary distance.
Never tried using carpet overhead but we used self adhesive carpeting (this stuff) to line the hull. It was a light beige colour. I lined the hull first with foam. The main problem was getting the stuff positioned right before letting it grab the foam - because it was immovable once in contact...

Can't remember where I got it - probably Amazon...
