Derivative Uses of The Name
To overcome the stability problems arising from the heavy turret mounted high in monitors, their hulls were designed to reduce other top weight. After Ericsson's ships, monitors developed the trunk deck design as the upper deck had to be heavily armoured against plunging shells. Because of the weight high in the hull, its breadth was minimized, giving rise to a vessel broad-beamed at the waterline, but with a narrow upper deck.
By analogy, nineteenth century railway coaches which were of the same shape to accommodate ventilators and lamps above the heads of standing passengers in the centre while to the sides, passengers were seated, were called monitors or monitor cars in the U.S.; the raised part of the roof was known as a turret. In ship design of around 1900, a turret deck was a more austere version of the trunk deck.

Famous quotes containing the word derivative:
“When we say “science” we can either mean any manipulation of the inventive and organizing power of the human intellect: or we can mean such an extremely different thing as the religion of science the vulgarized derivative from this pure activity manipulated by a sort of priestcraft into a great religious and political weapon.”
—Wyndham Lewis (1882–1957)
