In recent years it became common practice to mark snap-back zones on ships decks in the vicinity of mooring machinery, rollers and fairleads. However, industry advice with respect to identifying and marking snap-back zones came under review last year following an incident where a deck officer was seriously injured during a mooring operation when standing in a location that had not been identified as being within a snap-back danger zone.

All mooring ropes will stretch to some degree under tension and more so when constructed from synthetic fibre. When a mooring line parts under load, the sudden release of stored energy in the rope will cause it to recover its original length almost instantaneously. The two ends of the line recoil or snap-back towards or past their secured ends with great velocity and anyone standing within the snap-back zone risks serious injury or death. A snap-back zone is thus an area within which it is unsafe for persons to be positioned when ropes are likely to come under tension.
