The rigging of a sailing ship is made up of the ropes and/or chains used to support the ship's masts, yards and sails.[1] The standing rigging is used to support the masts.[1] The running rigging supports the yards and sails.[1] Some types of sailboats that have unsupported masts do not have any rigging.[2] These include the junk rig and catboat rigs.[2] Bermuda sloops with a single mast and one headsail use fairly simple rigging.[2] Cutter-rigged ketches and schooners have the most complex rigging.[2]
