Paddle steamer
A paddle steamer is a steamship or steamboat powered by a steam engine driving paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, whereby the first uses were wheelers driven by animals or humans.
In the early 19th century, paddle wheels were the predominant way of propulsion for steam-powered boats. In the late 19th century, paddle propulsion was largely superseded by the screw propeller and other marine propulsion systems that have a higher efficiency, especially in rough or open water.
Paddle wheels continue to be used by some ships that operate as excursion boats, floating restaurants, and casinos; these include replica vessels, and are often diesel powered.
Small pedal-powered paddle boats are also found, typically as novelty attractions.
The paddle wheel is a large steel framework wheel. The outer edge of the wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under water. An engine rotates the paddle wheel in the water to produce thrust, forward or backward as required. More advanced paddle-wheel designs feature "feathering" methods that keep each paddle blade closer to vertical while in the water to increase efficiency. The upper part of a paddle wheel is normally enclosed in a paddlebox to minimise splashing.
The three types of paddle wheel steamer are sidewheel, with one paddlewheel amidships on each side; sternwheel, with a single paddlewheel at the stern; and (rarely) inboard, with the paddlewheel mounted in a recess amidships.
The earliest steam vessels were powered by sidewheels, by far the dominant mode of marine steam propulsion, both for steamships and steamboats until the increasing adoption of screw propulsion from the 1850s. Though the sidewheels and enclosing sponsons make them wider than sternwheelers, sidewheelers may be more maneuverable, since some can move the paddles at different speeds, and even in opposite directions. This extra maneuverability makes sidewheelers popular on the narrower, winding rivers of the Murray–Darling system in Australia, where a number still operate.
European sidewheelers, such as PS Waverley, connect the wheels with solid drive shafts that limit maneuverability and give the craft a wide turning radius. Some were built with paddle clutches that disengage one or both paddles so they can turn independently. However, wisdom gained from early experience with sidewheelers deemed that they be operated with clutches out,[citation needed] or as solid-shaft vessels. Crews noticed that as ships approached the dock, passengers moved to the side of the ship ready to disembark. The shift in weight, added to independent movements of the paddles, could lead to imbalance and potential capsizing.[citation needed] Paddle tugs were frequently operated with clutches in, as the lack of passengers aboard meant that independent paddle movement could be used safely and the added maneuverability exploited to the full.
