Marine knuckle boom crane (1) comprising a crane housing (3, 15) which is rotational relative to a pedestal (9) about a vertical rotation axis (R) and a knuckle boom assembly attached to the crane housing (3, 15). The knuckle boom assembly comprises a main boom (4), the inner end of which is connected pivotably about a first horizontal pivot axis (20) to the crane housing (3, 15); and a jib (5), the inner end of which is connected pivotably about a second horizontal pivot axis (21) to the outer end of the main boom (4), herein the jib is pivotable at least between an extended position in which the tip extends mainly forward from the main boom (4), and a folded position in which the jibv (5) is folded back, essentially parallel along the main boom (4). In order to position the jib (5) with respect to the main boom (4), a tensioning member (11a, l ib) is provided extending between the crane housing (3, 15) and a curved extension guide (10) connected to the jib (5).
