A cable fairing 120 suitable for removable mounting to an umbilical cable (126, Fig 6) comprises a tube (100, Fig 1) comprising a central bore 102 shaped to restrict the bend of the umbilical cable and a tail fin (112, Fig 1) extending substantially radially from the tube. The tail fin is shaped to reduce drag on the tube when immersed in a flowing liquid. In use the cable fairing both reduces drag on and restricts the bending of underwater cables or pipes to prevent over bending of the cables or pipes. The cable fairing has a lower drag in a fluid flow than the cables or pipes themselves in order to reduce vortex formation. The central bore may have a circular cross-section and may have a maximum dimension at an upper and lower end of the bore with a minimum dimension (114, Fig 2) at a mid-point of the bore. The cable fairing may be formed from a buoyant material such as plastic foam.
