probably in the wrong category then. If a picture's worth a thousand words, look at the picture! The "ship" is roughly the length of 6 or 7 of those droids. How big are the droids? I dunno. But if this were 100m long, the droids would have to be much bigger than standard security droids.
I wouldn't say one way or another what size this "ship" is until I read the source material.
It was picked because it was listed specifically in the air vehicles category of the wiki, and Togan is correct; its like a cruise liner here on Earth, travelling around the oceans. Luxury Cruise liner is a fairly generic category.
