A self-propelled jack-up vessel has a centreline extending from a bow end to a stern end of the vessel along a central longitudinal axis, defining port and starboard sides of the vessel. The vessel comprises a hull, a deck and four retractable legs, which extend through the hull and the deck. The vessel includes a bow leg arranged on the centreline towards the bow, a stern leg arranged on the centreline towards the stern, and a starboard leg arranged at the starboard side. The diagonal placement of the legs, with respect to the centreline gives greater stability and flexibility. Further, a vessel is provided having a cruciform primary structural arrangement.
