Undersea Boat

Source: RC 239
An undersea boat looks identical to a riverboat (see below), and functions in all ways as one. If the command word is known, however, no crew is required- the boat will operate itself according to the commands of its owner. It can be commanded to start, stop, turn to port, turn to starboard or stop turning. Additionally, the boat can be commanded to submerge itself, level off, or surface, providing all passengers in contact with the boat with a continuous water breathing effect.
