The invention relates to a marine truss-type jib which comprises a second segmented boom located at the middle position of the jib, wherein the two ends of the second segmented boom are connected with a first segmented boom and a third segmented boom respectively by hinge pins. The jib disclosed by the invention is compact and reasonable in structure; a boom is made of a steel tube by welding and can be arranged in a segmented mode, so that the boom is easy to transport, and the weight of the jib is reduced; and when the jib operates with the wind, a steel tube truss structure can effectively reduce the wind resistance, so that a crane is more stable in operation.
