Symzonia: Voyage of Discovery

The shaft by which the power of steam was communicated to the paddles, passed through the inner side of the ship only, so that water could not be forced into the ship, even in the roughest weather, when the ports were closed. The inconvenience caused by the rolling of a vessel with upright wheels, was avoided by the obliquity of my paddles; the ship never rolling so much as to bring them to a perpendicular, or dip the nave to which they were fastened. To avoid accidents from fire, I built beneath and on the sides of the furnace and boiler of the engine, two narrow cisterns, perfectly tight, and of incombustible materials. These were kept constantly filled with the waste water of the engine, which was allowed to escape only by a spout at the top. No fire was permitted out of this enclosure. The economy of fuel, which was necessary from the length of the voyage, and from the emergencies which might happen, obliged me to adopt all the means of motion in my power. I therefore rigged my vessel as a ketch, with one large mast, and a long sliding topmast, which could be easily launched or sent up by the assistance of the engine; and a small mast abaft fitted to be struck at pleasure. Having thus constructed a vessel which possessed the qualities most essential to my purpose, I finished the interior in such manner as I judged best calculated to render myself and people comfortable during the voyage. I took care to have one apartment large enough to contain all my crew. This was situated next to the furnace chamber, and had communication with it, by means of a tight covered passage. By a tube from the furnace, heated air could be conveyed to this apartment, and steam from the boiler by another tube, should the state of the air at any time require it.
