A jack-up crane vessel or semi-submersible crane vessel is provided including a hull with a deck, and a crane on the hull for hoisting a load outside the deck. The crane includes a slewing crane base with a first suspension, an elongated boom that is rotatable around a horizontal rotation axis with respect to the first suspension, at least two pendants between the boom and the first suspension that mutually converge toward the distal boom section, a boom spacer between the boom and the first suspension, and a boom luffing installation for driving the rotation of the boom around the horizontal rotation axis between a lowered transport position and a raised operational position. In the direction of the vertical rotation axis the first suspension extends at least in the lowered transport position of the boom above the boom heel of the boom.
