What does brail mean?
A brail is a small but essential piece of rigging on a sailing vessel: one of several light ropes fastened along the after edge of a fore-and-aft sail, or along the foot of certain square sails, so that the canvas can be drawn up and secured against its spar without being lowered. Used collectively, brails allow a crew to shorten or furl a sail quickly from the deck — a maneuver known as brailing up. The word also functions as a verb ('the hands brailed the mizzen') and has an older fishing sense, describing the drawing in of a net or the taking of fish by that method. Brail is firmly a term of the sea, appearing in nautical manuals, historical fiction, and descriptions of traditional fisheries rather than in casual conversation. Its value today lies largely in evoking the practical texture of working sail, when a well-drilled crew could reduce canvas in seconds by simply hauling on a handful of slender lines.
A small rope attached to the leech of a fore-and-aft sail or the foot of a square sail, by which the sail is gathered up or furled.
"The mate ordered the brails rove off before they attempted to shorten sail."
Usually encountered in the plural, since several brails run along the edge of a single sail.
To haul in or furl a sail by means of brails; also, in fishing, to draw in or gather a net.
"They brailed up the mainsail and let the boat drift while they ate."
Typically used transitively, most often in the phrase 'brail up'.
The plural is standard and common because a sail normally carries several brails at once.
"Each of the brails led down to the deck within easy reach of the helmsman."
Before winches did the work, sailors furled big sails by hand simply by hauling on thin ropes called brails — the same trick fishermen still use to gather a net.

Etymology of brail
Brail entered English in late Middle English, borrowed from Old French, where related forms denoted a belt or strap — the underlying idea being a band or cord used to bind or gather something. It first appeared in English in nautical contexts, referring to the cords used to truss up a sail, and later extended to the gathering of fishing nets. The word shares this French origin with other seafaring vocabulary adopted into English during the medieval period, though it has remained a specialized mariner's term throughout its history.

How brail is actually used
Brail belongs almost entirely to nautical and historical register — you will encounter it in maritime writing, accounts of traditional fishing, and literature of the sea rather than everyday speech. It appears chiefly in the phrases 'to brail up' or 'brail in'. The spelling should not be confused with 'braille', which is unrelated despite the near-identical form.
