Sankaty was designed by Chauncey G. Whiton. [1] The ship was 195 feet (59 m) long, [1] a slim vessel with twin propellers and twin smokestacks. [2] She had a 36-foot (11 m) beam, [3] and 32 feet (10 m) at the waterline and drew 9 feet 6 inches (2.9 m) of water.
A steamship, often referred to as a steamer, is a type of steam-powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines [1] that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 19th century; however, there were exceptions that came before.

A pop-pop boat (also known as a flash-steamer, hot-air-boat, or toc-toc after a German version from the 1920s [1]) is a toy with a simple steam engine without moving parts, typically powered by a candle or vegetable oil burner. The name comes from the noise made by some versions of the boats.
It is standard equipment on large stationary boilers and was also fitted to large steam locomotives to ease the burden of the fireman. The locomotive type has a screw conveyor (driven by an auxiliary steam engine) which feeds the coal into the firebox. The coal is then distributed across the grate by steam jets, controlled by the fireman.
Compound engines, in which steam was expanded twice for greater efficiency, were first used on the Great Lakes in 1869. Triple-expansion engines , for even greater efficiency, were introduced in 1887 and quadruple-expansion engines , the ultimate type of reciprocating engine for speed, power and efficiency, appeared on the lakes in 1894.
An oscillating cylinder engine cannot be reversed by means of the valve linkage (as in a normal fixed cylinder) because there is none. Reversing of the engine can be achieved by reversing the steam connections between inlet and exhaust or, in the case of small engines, by shifting the trunnion pivot point so that the port in the cylinder lines up with a different pair of ports in the port face.
