They work. However they are a lot slower - by enough that no shipping company can compete using them. I’m not clear on if they scale to the size of modern ships either.
They 100% work - just as well as they did in 1700. The slow speed means nobody will use them exclusively. I’m not sure if they need extra labor as well (assuming modern controls) but that is another potential reason nobody would use them. They couD though.

Pretty sure they don’t, at least not as a total replacement. Reducing fuel usage is still a possibility maybe.
