A plugin is not required, although older computers may have issues running it. It does not work in Internet Explorer 10 or earlier.

Not a dumb question. I have no idea about the observing capabilities of this particular ship. Some obs are pretty bad, some are good. Some observers may be better than others. Can't tell the duration of that 35kt wind.
