In a traditional hemp and sandbag rigging system the clew is used to join the several ropes which support the batten to a single control line. This control line is then tied to the belaying pin on the pin rail, or counterbalanced with sandbags.

The reason the clew is necessary is because older theatres often used wooden battens. On a wide stage several ropes were needed to support this batten. Without the clew to join ropes each rope would have to be individually sandbagged. Moving a single batten would require as many riggers as there are ropes. With a clew, one single rope can control the series of ropes,thus allowing the lineset to be operated by just one person.

In sailing, the bottom corner of a sail opposite the end touching the mast.

Most sails have a grommet at their clew so they can be tied down to the boom. Usually a rope called an Outhaul is used to provide tension, stretching the sail. The tighter the sail, and less baggy, the more wind can skim off of it, giving more control for less power. This outhaul can be placed in a block or a cleat so it can be adjusted constantly during a race.
