Reasons for Using Mooring Tails When using mooring ropes, there is a general desirability for the additional elasticity provided by mooring tails. The additional elasticity reduces the loads induced in wire mooring lines under dynamic loadings by permitting the ship to respond more favorably to various combinations of wind, wave and current, as well as to ships passing at slow speeds in close proximity. Tails also tend to distribute the loadings more evenly in the mooring lines in the same ser
