    Abstract: A luffing jib backstop assembly for limiting rotation between a luffing jib and a boom to which the luffing jib is attached is disclosed. The assembly comprises at least one backstop pendant attached at a first end to the luffing jib and at a second end to the boom, the pendant having a length sufficient to allow the luffing jib to be extended to an angle of 180.degree. with respect to the boom. The assembly further comprises a deployable member which engages the backstop pendant and which, upon full deployment, holds a portion of the backstop pendant away from the boom and luffing jib such that the pendant and deployable member prevent the luffing jib from rotating with respect to the boom beyond a permissible operating angle.
