Look up moonraker in Wiktionary, the free dictionary.
A moonraker, also known as a moonsail, [1] hope-in-heaven, or hopesail,[ citation needed ] is a square sail flown immediately above a skysail (see sail-plan) on the royal masts of a square-rigged sailing ship. None of the four- and five-masted square-rigged ships carried a moonsail.[ citation needed ]
The equivalent sail, if triangular, is called a skyscraper. [1]
Moonrakers are relatively unusual sails only used on ships built primarily for speed.[ citation needed ]
