Small boat that can be used to cross *SMALL* bodies of water (8? coords max and depth of the water also matters). Can be disassembled for a full refund (don't tear down) with all the parts going directly into your inventory.
When building it, changing the direction of the ferry is purely for aesthetic purposes - the path taken by the ferry appears determined by the landscape (nearest shore at 90 degrees to the lay of the land where it's built?).
Built: outside
Skill/Tech required: Ferry Construction
