A shade sail is a device to create outdoor shade based on the basic technology as a ship's sail. Shade sails use a flexible membrane tensioned between several anchor points. While generally installed permanently, they are cheap and easy to set up. They are usually provided above public gathering places such as seating areas and playgrounds in countries where strong sun radiation makes prolonged stays in the open sun unpleasant or dangerous due to sunburn and skin cancer risk.

Famous quotes containing the words shade and/or sail:
“Superstition, bigotry and prejudice, ghosts though they are, cling tenaciously to life; they are shades armed with tooth and claw. They must be grappled with unceasingly, for it is a fateful part of human destiny that it is condemned to wage perpetual war against ghosts. A shade is not easily taken by the throat and destroyed.”
—Victor Hugo (1802–1885)
“Was it the proud full sail of his great verse,
Bound for the prize of all too precious you,
That did my ripe thoughts in my brain inherse,
Making their tomb the womb wherein they grew?
Was it his spirit, by spirits taught to write
Above a mortal pitch, that struck me dead?”
—William Shakespeare (1564–1616)
