Operation
Typically, such a feature consists of a slope, with one or more rail tracks on it. Boats are raised between different levels by sailing into water-filled tanks, or caissons, with wheels on the bottom and watertight doors at each end, and are perpendicular to the slope. These are drawn up or down hill on the rails, usually by means of cables pulled by a stationary engine. In most designs two caissons are used, one going up and one down, acting as counterweights for greater efficiency. When the caisson has reached the top or bottom of the slope, the doors open and the boat leaves.
There are also inclined planes without a tank or caisson, instead carrying vessels up out of the water cradled in slings or resting on their keels. In a few cases the boats were permanently fitted with wheels.

Famous quotes containing the word operation:
“An absolute can only be given in an intuition, while all the rest has to do with analysis. We call intuition here the sympathy by which one is transported into the interior of an object in order to coincide with what there is unique and consequently inexpressible in it. Analysis, on the contrary, is the operation which reduces the object to elements already known.”
—Henri Bergson (1859–1941)
“You may read any quantity of books, and you may almost as ignorant as you were at starting, if you don’t have, at the back of your minds, the change for words in definite images which can only be acquired through the operation of your observing faculties on the phenomena of nature.”
—Thomas Henry Huxley (1825–95)
“Waiting for the race to become official, he began to feel as if he had as much effect on the final outcome of the operation as a single piece of a jumbo jigsaw puzzle has to its predetermined final design. Only the addition of the missing fragments of the puzzle would reveal if the picture was as he guessed it would be.”
—Stanley Kubrick (b. 1928)
