Moonscape is interesting. I’m not sure how often the last part of her ability will come into play, as outside of campaigns there usually isn’t a whole lot of terrain and islands usually don’t get that close to each other, even if they’re Great Turtles :D.
That aside, this is a nice two way ship. You could very easily make her a gunship, given that her cannons are not too terrible. You could also go the route of a gold runner, though you’d either need an accompanying hoist, or a crew that allows you to unload within s of your home island.
