These directions, for example, may correspond with the bow-stern, stern-bow, port-starboard, and starboard-port directions of the vessel 120, for example when the first skid rail arrangement 181 is aligned with the bow-stern direction of the vessel 120 and the second skid rail arrangement 186 is aligned with the port-starboard direction of the vessel 120. As the first and second frame assemblies 200, 600 are each moveable in four directions, they may thus each be considered as being quadridirectionally moveable.
