Gibraltar has a one metre tidal range which means that cruise ships can berth alongside the Cruise Terminal at any time of day or night within an hour of leaving the main shipping lanes of the Strait of Gibraltar.
Cruise ships and other vessels calling for bunkers or water can be accommodated on both sides of the Western Arm. The outer side is 490 metres long with a maximum draught of 9.6 metres and can accommodate vessels of any length. The inner side is 450 metres long with a maximum draught of 8.6 metres and can accommodate vessels up to a maximum length of 300 metres.
Deeper draught vessels can be berthed according to tide. Vessels calling for lay-up or repairs can also berth at the Detached Mole, which is 605 metres long with a maximum draught of 9.1 metres. Two 100 metre berths are also available for vessels discharging general cargo (containers).
