"That would depend on your frame of reference. A larger vessel will have more sails to make up for its increased energy requirements, while smaller boats need fewer. For example, the great Arcturian merchantships can have upwards of nine sails on each of its four masts, whereas my own ship merely has three sails at most on the main mast." Amelia pauses a moment, thinking of a better way to explain. She settles on a diagram of sorts, using her sword to sketch out a rough outline of the Legacy in the dirt. By no means is she an artist, but it resembles the profile of her ship closely enough.
