Banedon's ship the Skyrider, later the Cloud Hopper, I believe was his next ship after the Skyrider was destroyed, it should be bigger on the inside. It is a magical ship, after all, so it should be like the TARDIS and be much bigger on the inside.
Its just a ship.. that flies. Thats all, just a normal ship like would be in the sea, except it flies. The Tardis is only like it is cause its camoflague unit is broken so is stuck looking like a police box. Tardis's in their natural state are as big as the inside, ie everythings in proportion. Nor is this like an abode in Harry Potter where its small on the outside but inside its huge (like in the Goblet of Fire). Dont forget, the whole LW universe was created by JD as a way to run his DnD campaigns, so the rules of the world regarding magic etc in the DnD are gonna be pretty much the same in the LW world.
