In literature:

Not a brace swung loose, not a plank was sprung, no spar was shivered.

Spars and lances of light upon the shivering waters, red and yellow and white!
"The Lure of the Mask" by Harold MacGrath

In poetry:

And all their quivering royals and all their singing spars
Should send a ghostly music a-shivering to the stars —
A sound like Norway forests when wintry winds are high,
Or old dead seamen's shanties from great old days gone by, —
"Ghosts In Deptford" by Cicely Fox Smith
In trim betimes they turn from land,
Some shivered sails and spars they stow;
One watch, dismissed, they troll the can,
While loud the billow thumps the bow--
Vies with the fist that smites the board,
Obstreperous at each reveller's jovial word.
"The Haglets" by Herman Melville
