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:
“Poor John Field!—I trust he does not read this, unless he will improve by it,—thinking to live by some derivative old-country mode in this primitive new country.... With his horizon all his own, yet he a poor man, born to be poor, with his inherited Irish poverty or poor life, his Adam’s grandmother and boggy ways, not to rise in this world, he nor his posterity, till their wading webbed bog-trotting feet get talaria to their heels.”
—Henry David Thoreau (1817–1862)
