Boom bales, also called boom bails, are mounted to the boom and are used to attach blocks for the mainsheet and vang. For most applications Standard Pivoting Boom Bails, which attach with a single Bolt, are used. To select a standard bale you will need to know the maximum width of the boom section. On smaller boats, standard and small boom bales are frequently mounted to the mast for attachment of a boom vang.
