running backstay - Also runner, or preventive backstay. A stay that supports the mast from aft, usually from the quarter rather than the stern.
A running backstay always attaches to the mast at a point below the top of the mast and is generally used in conjunction with a permanent backstay. Running backstays are found on both masthead rigs and fractional rigs.
An important point with cutters and most double-headsail rigs is that running backstays are required to properly tension the staysail stay.

The 7/8 fractional rig with sweptback spreaders does not require running backstays. The standard, keel-stepped mast and boom are aluminum, with carbon fiber offered as an option. Two reefs and a flattening reef are standard, as is a Hall Spars vang.
Backstay: A mast support that runs from the top of the mast to the stern of the yacht; it may be adjustable in order to bend the mast backward or to increase tension on the forestay. See Running Backstay.
A backstay adjustor is a block and tackle or hydraulic system that adjusts the backstay's tension. Running backstays (runners) go partway up the mast on the starboard and port sides and may be adjusted and disconnected at the deck.
