I like my maps, and here is Wakes, taken from ingame!
Standard Metroidvania fare. It shows the rooms and doors. Oh and it's colour coded to the type of area its set in. Shops are purple, cabins are green. It doesn't show the other layer of the map though, and since it's supposed to be "off limits" so there isn't a corresponding map.
At the last measurement the ships length is around 450 metres.
