Square. Yards are squared when they are horizontal and at right angles with the keel. Squaring by the lifts makes them horizontal; and by the braces, makes them at right angles with the vessel's line. Also, the proper term for the length of yards. A vessel has square yards when her yards are unusually long. A sail is said to be very square on the head when it is long on the head.

To square a yard, in working ship, means to bring it in square by the braces.
